-Overview of Changes from GIMP 2.10.0 RC1 to GIMP 2.10.0
-=======================================================
-
-Core:
-
-  - CLI option --show-playground visible in --help.
-  - Sample point dockable now works with more than 4 sample points.
-  - Various warnings removed, multi-threading officially not
-    "experimental" anymore…
-  - Various fill and fade operations now use the current paint composite
-    mode, allowing for instance filling to paint over transparent areas.
-  - Default layer and paint modes are now Normal (instead of Legacy).
-  - Be smarter about layer modes for new layers.
-  - Get rid of the remaining places that were using the NORMAL_LEGACY
-    mode by default (painting, some more).
-  - Improve painting speed even more by even more evil C++.
-  - Flipping drawables is much faster because it's now working
-    tile-by-tile.
-  - Gradient rendering is now much faster, using a cache.
-
-Plug-ins:
-
-  - Ripple plugin removed, compat PDB-API "plug-in-ripple" added
-    instead.
-
-PDB:
-
-  - New procedure: gimp-item-transform-translate.
-  - Make gimp-item-transform-* transform linked items too.
-  - Deprecate gimp-color-balance and gimp-layer-translate.
-
-Assets / Resources:
-
-  - New "Fun" category for brushes (moving the "Pepper" there, which
-    also gets improved resolution), and adding Wilber and GEGL brushes.
-  - "Structure" brush obsoleted.
-  - 5 new and more serious brushes.
-
-Translations:
-
-  - 6 translations were updated: Catalan, Danish, Finnish, Korean,
-    Polish, Swedish.
-
-
-Overview of Changes from GIMP 2.10.0 RC1 to GIMP 2.10.0 RC2
-===========================================================
-
-Core:
-
-  - Symmetries are now preserved in XCF files (saved as image parasites).
-  - New runtime option --show-debug-menu in order to make the File >
-    Debug menu visible.
-  - Do not show invisible actions in search dialog.
-  - Do not dither image mask and channels for imported images.
-  - Various optimizations for painting and display (WIP), including
-    parallelized painting code.
-  - New "Misc" group to the Dashboard dock, with currently only a
-    "Mipmapped" field showing the total size of processed mipmapped
-    data.
-  - Plug-ins debugging on crashes through --stack-trace-mode CLI option
-    improved to handle more case.
-  - Fix selection -> channel -> selection roundtrips by never doing
-    any gamma conversion when converting between an image's selection,
-    channels, masks. Also, make all channels linear in all images with
-    >8bit.
-
-Libgimp:
-
-  - New group "drawable_edit" which contains all functions from "edit"
-    that are not cut/copy/paste. The new functions have much less
-    arguments and take them from the context instead. The respective
-    functions in "edit" have been deprecated.
-  - New functions in "context" to configure aspects of gradient
-    drawing, and to set the built-in gradients (the new gradient
-    function in "drawable_edit" doesn't have a parameter for the
-    gradient type any longer).
-
-User interface:
-
-  - Lighter and Darker themes removed for now, Light and Dark themes
-    rewritten from scratch to get rid of various usability issues and
-    glitches. Only Gray theme from previous set kept as-is.
-  - New GimpToolGyroscope on-canvas control, currently used for
-    the Panorama Projection filter. The widget provides on-canvas
-    interaction for 3D rotation (yaw, pitch, roll).
-
-Configurability:
-
-  - In Preferences > Dialog Defaults, new section "Filter Dialogs"
-    created to customize various common features of filters, such as
-    recent settings and advanced color options.
-  - Do not default to last used filter settings, but allow this behavior
-    in Preferences > Dialog Defaults, with checkbox "Default to the last
-    used settings".
-
-Tools:
-
-  - Color used in the Smudge tool is now added to the color history.
-  - "Blend" tool renamed to much more consistent "Gradient" tool.
-    Also it can now work in linear RGB matching capabilities CSS/SVG
-    specification without gamma-errors in color blending and CIE Lab
-    which in addition keeps a perceptual graylevel.
-
-Assets / Resources:
-
-  - Adding 4K UHD in document templates (and fixing 4K DCI).
-
-Building:
-
-  - New --enable-bundled-mypaint-brushes option in configure to decide
-    whether to use the configure-time installation path of MyPaint
-    brushes, or use a path relative to GIMP installation prefix
-    (typically for bundled binaries, such as on Windows or macOS).
-  - Detect freetype2 using pkg-config (`freetype-config` is on its way
-    out in various distributions apparently).
-  - Appdata now installed to $PREFIX/share/metainfo/
-
-Translations:
-
-  - 8 translations were updated: Arabic, Catalan, Chinese, French, Italian,
-    Polish, Russian, Swedish.

-
-Overview of Changes from GIMP 2.9.8 to GIMP 2.10.0 RC1
-======================================================
-
-Core:
-
-  - New dashboard dockable: shows the current GEGL cache and swap sizes
-    and CPU usage and active time, and their recent history. It has
-    options to control the update rate and history duration of the data,
-    and an option to warn (by raising/blinking the dialog) when the swap
-    size approaches its limit.
-  - Make the selection boundary detection the same as 2.8.
-  - The environment variable GIMP_DEBUG can now be set to "list-all" to
-    display available debug domains. Non-recognized flags will also
-    trigger the debug flag list output.
-  - Improve migration from 2.8 to 2.10 by recursively migrating
-    configuration files (up to 5 levels, to protect from recursive
-    symbolic links).
-  - Mark legacy plug-ins and scripts in menus.
-  - Enable "save-tool-options" and "save-device-status" by default,
-    it's the expected behavior these days.
-  - GIMP doesn't warn any more for unknown darktable XMP metadata. We now
-    register the corresponding namespace.
-  - Adding settings for metadata export handling in "Image Import &
-    Export" page of Preferences. By default, the settings are checked,
-    but you can uncheck them (in particular since metadata can often
-    contain a lot of sensitive information).
-  - Splash image now scaled down to maximum 1/2 of the screen area. This
-    will allow to ship a big splash image which will be visible on all
-    type of screens, whichever low or high resolution. Vector splash
-    images are scaled both up or down to have them always at ideal size.
-  - Brightness-Contrast, Curves, Levels and Threshold are now available
-    in "Repeat last" history.
-  - Improve action history to not show newly excluded actions (which
-    were already in our history from before the exclusion).
-  - Use GEGL for transform-tools preview, allowing faster and more
-    accurate previews.
-  - Re-arrange color models in the Color dock (WIP).
-  - New debug tool and infrastructure to handle WARNING and CRITICAL
-    errors, as well as fatal errors (crashes), raising a pop-up with all
-    version information on GIMP and its main dependencies, as well as
-    the error message and backtraces, and encouraging people to make bug
-    reports.
-  - Support layer masks on layer groups.
-  - GIMP now attempts to backup unsaved images when it crashes. Then at
-    next startup, it will suggest to recover the salvaged images. Image
-    recovery is not 100% guaranteed.
-  - New gimp_spawn_async() function uses vfork() to help avoid hanging
-    during a fork process, currently used for plug-ins.
-  - Dock color picker is now color-managed on macOS.
-
-Libgimp:
-
-   - New gimp_export_exif(), gimp_export_xmp() and gimp_export_iptc()
-     functions returning the creator choice regarding default handling
-     for metadata export (as set in the Preferences).
-   - GIMP Protocol version incremented.
-   - New gimp_get_pdb_status() to return the status of the last PDB
-     call. This is needed for plug-ins which depend on other plug-ins'
-     procedures. If for instance, a second-level plug-in is interrupted
-     interactively, we don't want to process this as an error but as a
-     cancellation.
-   - New gimp_stack_trace_available(), gimp_stack_trace_print() and
-     gimp_stack_trace_query() for debugging.
-   - Use gegl:distance-transform in gimp_edit_blend() implementation
-     making it much faster for all GRADIENT_SHAPEBURST_* gradient types.
-     Legacy gimp:shapeburst operation has been deleted.
-   - New gimp_context_get_distance_metric() and
-     gimp_context_set_distance_metric() for distance metric used in
-     gimp_edit_blend() (and future usage).
-
-GUI and Usability:
-
-  - New icons: "gimp-attach", "gimp-color-space-linear",
-    "gimp-color-space-perceptual", "gimp-color-temperature",
-    "gimp-dashboard", "gimp-detach", "gimp-tool-desaturate",
-    "gimp-tool-exposure", "gimp-tool-shadows-highlights".
-  - Switching between linear and perceptual (gamma-corrected) spaces
-    in the Histogram dialog is easier now: two buttons instead of one
-    two-way button where current state was difficult to understand.
-  - Shorten color channel labels in the color frame (color picker tool,
-    sample point editor…) with conventional 1 or 2-letter abbreviations,
-    and split coordinates on 2 lines.
-  - We now switch to "Huge" icons by default when the display pixel
-    density is over 250 PPI (used to be 300 PPI).
-  - Improve action history sorting: items climb up the list faster,
-    while top items retain their relative position longer.
-  - Extend action search "initialism": Extend initialism-based search
-    (e.g.: "gb" for "Gaussian Blur"), by matching arbitrarily-long
-    initialisms, and by allowing partial matches (with lesser priority).
-  - Values in the GimpNumberPairEntry widgets can now be cleared by clicking
-    an icon.
-  - Transform Grid controller is now available for custom UIs of GEGL
-    operations (currently used for Recursive Transform op).
-  - New GimpHighlightableButton widget is used to draw attention to buttons
-    in certain cases. Currently used for anchoring and removing floating
-    selections.
-  - Composite modes were renamed to be more descriptive, as follows:
-    Source Over       =>  Union
-    Source Atop       =>  Clip to Backdrop
-    Destination Atop  =>  Clip to Layer
-    Source In         =>  Intersection
-
-Configurability:
-
-  - Wilber logo in the toolbox can now be disabled via Preferences
-    (the Toolbox page).
-
-Tools:
-
-  - "Link brush size with canvas zoom" paint option becomes "Lock brush
-    to view" to make a brush invariant in display space whichever
-    scaling, rotation, and reflection.
-  - Blend tool now displays the line length (in current shell unit and
-    with ideal digit accuracy) and angle in the status bar.
-  - Constrain line angles in display space: all tools which have a line
-    constraint feature (for instance blend tool, paint tools in line
-    mode, etc.) will now do so relatively to the display, allowing you
-    to rotate the canvas in order to constrain to any arbitrary angle.
-  - Levels and Curves can now work on linear light data, the toggles are
-    at the top of respective dialogs, right next to linear/log toggles
-    for the histogram.
-  - Blend tool now has a distance metric option to determine how
-    distances are computed (Euclidean, Manhattan or Chebyshev
-    distances).
-
-Filters:
-
-  - New GEGL-based Shadows-Highlights filter now available in the Colors
-    menu. The implementation is based on the code from darktable.
-
-Plug-ins:
-
-  - Screenshot with the generic Freedesktop API has been implemented. It
-    is meant to replace all desktop environment specific APIs eventually
-    but needs to get reasonable features first. Therefore currently
-    GNOME/KDE and X11 implementations still have priority.
-  - qbist ported to GEGL and float.
-  - Colors for the standard output and standard error texts in the
-    Python console are now themeable, mapping respectively to normal
-    text and insensitive text colors for the "python-fu-console" widget.
-    We updated the default colors a bit for our themes. If this is not
-    good enough (for instance, if one has a specific type of color
-    blindness), at least it is now possible to create a custom theme
-    adapted to one's needs.
-  - PSD export now happens with progress bar update for feedback.
-  - Win32 Screenshot improved to handle hardware-rendered software and
-    multi-monitor displays.
-
-File formats:
-
-  - Fix various vulnerabilities in file plug-ins: GBR (CVE-2017-17784),
-    PSP (CVE-2017-17787 and CVE-2017-17789), TGA (CVE-2017-17786) and
-    FLI (CVE-2017-17785).
-  - Fix WebP export under Windows.
-  - No more max dimension limitation for X cursors. We still warn when
-    cursor size is over a max limit for X bitmap cursors, but we don't
-    clamp anymore on export.
-  - JPEG, PNG, TIFF and WebP export plug-ins updated to honor creator's
-    default choice regarding metadata handling.
-  - Fix GIH brushes using different-sized layers.
-  - RGBE (Radiance HDR) format files can now be imported and exported.
-  - JPEG2000 loading now done via OpenJPEG library and supports any bit
-    depth (over 32-bit per channel will be clamped to 32-bit and
-    non-multiple of 8-bit will be promoted, for instance 12-bit will end
-    up as 16-bit per channel in GIMP). JPEG 2000 codestream also
-    supported and displays a dialog asking for the color space (whereas
-    JPEG 2000 image color space are auto-detected).
-    JPEG 2000 images or codestream in YCbCr, xvYCC and CMYK color spaces
-    are converted to sRGB images upon loading.
-
-Building:
-
-  - poppler and poppler-data now hard dependencies. PDF import is
-    considered a granted feature nowadays and fallbacking to the
-    Postscript plug-in was bad experience.
-  - move PDB generation and sources to toplevel/pdb.
-  - New configure option `--enable-windows-installer` to generate the
-    necessary files for the installer translations during the build.
-  - Improve POTFILES generation for po-*/ directories.
-  - Require glib >= 2.54.2.
-  - New dependency to mypaint-brushes-1.0 for stable MyPaint brushes
-    available at installation.
-  - AppStream ID renamed from gimp.desktop to org.gimp.GIMP following
-    current convention.
-  - Require fontconfig >= 2.12.4. Lower versions are particularly a
-    problem on Win32, where many cache update failure were reported to
-    us, resulting in very slow startup and close-up (and not only the
-    first time, but every time).
-
-Translations:
-
-  - Windows installer now localized with gettext.
-  - String freeze has started and GIMP received updates from:
-    Basque, Brazilian Portuguese, Catalan, Chinese (Taiwan), Danish,
-    Esperanto, French, German, Greek, Hungarian, Icelandic, Italian,
-    Japanese, Latvian, Polish, Russian, Serbian, Slovenian, Spanish,
-    Swedish, Turkish.
-
-
-Overview of Changes from GIMP 2.9.6 to GIMP 2.9.8
-=================================================
-
-Core:
-
-  - The default brush is now "Hardness 050".
-  - Verbose version (command line: gimp -v) now displays C compiler
-    information.
-  - Transform tools don't commit identity transformation anymore.
-  - Manual language can now be selected amongst all installed manuals,
-    which is particularly interesting when no GIMP manuals are available
-    in your GUI language. This will be proposed by default when a manual
-    is not installed for the GUI language (alongside the possibility to
-    read online) and the choice can be edited in preferences.
-  - The statusbar now blinks on warnings and errors.
-  - Paste in Place, available for regular clipboard and named buffers,
-    allows pasting contents of either the clipboard a named buffer at the
-    exact coordinates it was copied from.
-  - Color Picker should now work on KDE/Wayland.
-  - Color Picker now reads values under cursor in local windows making
-    it work at least inside GIMP Windows on Wayland platforms with no
-    color-picking capabilities (for instance GNOME/Wayland) yet.
-  - OpenCL is now disabled by default. Depending on graphics cards and
-    drivers, OpenCL acceleration is often slower than multi-threaded
-    implementation, and can also sometimes be "glitchy".
-  - Now possible to open a locally-installed manual different from the
-    GUI localization. The manual language choice can be customized
-    through preferences when several manuals are installed. If no manual
-    language has been selected already and no manual for current GUI
-    localization is available, choice of help language will be proposed
-    at first call to the manual.
-
-Configurability:
-
-  - Keybindings now possible for previous/next/top/bottom channel.
-
-Usability:
-
-  - The spinscale widget now highlights vertical parts of the slider
-    section differently to hint that position of cursor above the widget
-    matters. When changing values in the lower step section, the pointer
-    will be wrapped around the screen so that you could continue adjusting
-    the value without interruptions.
-  - Canvas rotation and flip information is now visible in the status
-    bar (as angle value and flip icon). Clicking on these canvas status
-    will respectively raise the "Select Rotation Angle" dialog or unflip
-    the canvas.
-  - Use abbreviated versions for long layer mode names. In particular,
-    replace the "(legacy)" suffixes with "(l)" in the abbreviated
-    versions, still showing the unabbreviated names in the full list.
-
-Tools:
-
-  - Blend tool now features on-canvas gradient editing: adding, shifting,
-    removing color stops, shifting midpoints and converting them to color
-    stops, assignging colors to color stops, changing blending type
-    for midpoints. Additional options: 'Instant mode' (active before you
-    start blending) to support the old workflow where you can't edit color
-    stops before applying the gradient fill, and 'Modify active gradient'
-    which allows changing user-writable gradients directly rather than
-    creating copies of them. Moreover, custom gradient is now saved
-    and restored across sessions.
-  - All transform tools: it makes no difference now whether a modifier is
-    pressed before of after mouse button press/release.
-  - Free Select tool selection can now be committed with double click as
-    well (only through Enter key before). This allows smoother workflows
-    on some setups, and in particular when no keyboard is available
-    (e.g. tablet-like computers).
-  - Layer group children now inherit the color tags of the parent by
-    default, unless specific color tags are assigned. Inherited color
-    tags show in a less saturated color than assigned ones.
-
-Painting:
-
-  - When copying a generated brush, GIMP now copies its 'Spacing' property.
-  - Rename "Wheel" dynamics labels as "Wheel/Rotation". It turns out
-    that Wacom Art Pen and Airbrush pen use the same axis for barrel rotation
-    and wheel scrolling respectively. Therefore they already work in GIMP.
-    "Unhide" the feature with more obvious labels.
-
-Color management:
-
-  - Use babl to convert between profiles if possible.
-
-Display filters:
-
-  - New 'Clip Warning' display filter to show underexposed and overexposed
-    values. Target values below 0 and above 1.0, hence it only works on
-    16/32 bit per channel float images (such as EXR and TIFF).
-  - Display filters now operate in unbounded sRGB rather than in monitor
-    color space.
-
-Plug-ins:
-
-  - Fix finding raw loaders on Windows/macOS.
-  - Screenshot for KDE/Wayland has been implemented (full-screen and
-    window screenshots only; rectangular area screenshots need
-    implementation on the KDE side).
-  - Screenshot can now add a delay between window pick/rectangular
-    area selection and the actual shot, but only in platforms supporting
-    the feature.
-
-File formats:
-
-  - PSD:
-    - Fix mask position when opening/exporting.
-    - Fix active layer selection during loading.
-    - Fix potential group-layer naming conflict during loading.
-    - Fix missing some attributes loading empty layers.
-    - Fix reading files with deeply nested layer groups.
-    - Load and save layer group expanded state.
-    - Improve layer opacity loading/saving.
-  - PDF: password-protected files can now be imported.
-  - HGT: Digital Elevation Model data from NASA/NIMA can now be loaded,
-    both SRTM-1 (1 arc-second) and SRTM-3 (3 arc-seconds).
-
-Filters:
-
-  - Update GEGL-based filter Wavelet Decompose:
-    - Add an option to keep the decomposition in a layer group.
-    - Add an option to add layer mask to each scales layers.
-    - Do not use 'New from visible' because it produces unexpected
-      results; replaced by succession of layer copy and merge down.
-
-PDB:
-
-  - Add file-pdf-load2 API to load password-protected and/or multi-page
-    PDF files.
-  - Add file-hgt-load to load HGT files, with an argument to select between
-    SRTM-1 and SRTM-3 types.
-
-Translations:
-
-  - Updated: Catalan, Croatian, Galician, German, Greek, Hungarian,
-    Icelandic, Indonesian, Italian, Polish, Russian, Spanish.
-
-Building:
-
-  - Require LittleCMS >= 2.8.
-  - Initial docker-based build environment for GIMP now available.
-  - Warn against use of GCC 7.2 which has a bug breaking GIMP.
-  - An official flatpak stable package is now available on flathub.

-Overview of Changes from GIMP 2.9.4 to GIMP 2.9.6
-=================================================
-
-Core:
-
-  - Make it possible to use multithreading in GEGL and raise max amount
-    of threads to 64. Given how unstable this feature is, any value
-    above 1 should be currently treated as a step inside an industrial
-    microwave oven with the on/off switch on the outside.
-  - New clipboard implementation allows copying/pasting layers and
-    layer groups.
-  - Color tags simplify managing large projects with a lot of layers
-    and layer groups.
-  - The Mouse Pointer dialog and colors applied to images are now
-    color-managed.
-  - Gamma and precision selectors for newly created images.
-  - Never dither when converting to a higher bit depth, or to anything
-    more than 16 bits; don't offer dithering options in these cases.
-  - Default to linear TRC when converting to 16-bit float.
-  - Pre-initialize some babl-based pixel format conversion routines
-    at start-up to decrease the initial lazy intialization cost for
-    some interactions.
-  - Remove max size limitation of 4GB for XCF files.
-  - Support clipboard images in the clipboard brush and pattern.
-  - libgimp calls are now thread-safe.
-
-Layers and compositing:
-
-  - Layer modes' code is now refactored to separate gamma-corrected
-    variations from the linear light ones, legacy modes have been
-    preserved to support older XCF files. UI to switch between the two
-    is experimental and should be treated as a temporary design.
-  - Blending and compositing of layers are configurable separately for
-    more flexibility now, compositing can be linear TRC, perceptual TRC
-    or CIE LAB.
-  - Layer blending color space and compositing color space are
-    configurable now.
-  - Layers created from the GUI and from plug-ins now default to
-    normal mode (not normal-legacy), unless all the existing layers
-    in the image are also in legacy mode.
-  - New layer modes: linear burn, vivid light, linear light, pin light,
-    hard mix, exclusion, merge, split, luminance (rgb), pass-through
-    (for layer groups only).
-  - Make erase mode an ordinary layer/paint mode.
-  - Better performance of HSV-based layer modes.
-  - Rename "Color (HSV)" mode to "Color (HSL)" to indicate the actual
-    color space being used.
-
-On-canvas interaction changes:
-
-  - Refactor on-canvas interaction code out of some of the tools and
-    make it reusable.
-  - Update tools accordingly.
-  - Make on-canvas interaction accessible to GEGL-based filters and
-    use it in the Spiral and Supernova filters as a test case.
-
-GUI and usability:
-
-  - Easily add or remove layer masks by clicking either the layer
-    preview or a new button in the Layers dialog.
-  - Enhance the Layer Attributes dialog to provide the single UI for
-    setting layer's name, blending mode, opacity, and offset,
-    toggling visibility, link status, various locks, color tags.

-  - Quick Mask and Channel Attributes dialogs use the new spinscale
-    widget for the  mask opacity slider.
-  - Enable grid views of dynamics and tool presets.
-  - Allow to zoom with middle mouse button + control + drag up/down.
-  - For all paint tools, when switching to the color picker mode,
-    don't rely on the exact modifier being pressed or released. Instead,
-    check if only the right modifier is pressed after *each* modifier
-    change, and switch to color picking if it is.
-  - On startup, GIMP checks for duplicate accelerators in menus, and
-    removes duplicates.
-  - Standard (Freedesktop) and GTK+ icons can now be set by the icon
-    theme for a fully consistent style.
-  - Many new icons.
-  - Toolbox buttons do not grab focus anymore, which used to break
-    usage of the Tab key and other canvas-related shortcuts after
-    changing tools with a pointing device click.
-  - Delete Layer/Channel/Path are consistently the last option in
-    respective dialogs now.
-  - Extend the text along the tangent of the last path stroke, when

-  - Shift-clicking the visibility icon of a layer in a layer group now
-    toggles its exclusive visibility within this layer group.
-
-Color selection and management:
-
-  - Add the profile import policy to Preferences -> Import.
-  - Color management for GEGL-based filters is expensive, so it's off
-    by default for now, and options are hidden by default too.
-  - Add LCH color selector, with support for gamut checking.
-  - Default to magenta for out-of-gamut color.
-  - Make all script-fu color buttons color-managed.
-
-Configurability:
-
-  - Remember settings of many dialogs across sessions.
-  - New Interface / Dialog Defaults page in the Preferences dialog to
-    control defaults values of various dialogs.
-  - Settings on some individual pages of the Preferences dialog can be
-    reset separately now.
-  - Vertical scrollbar added to keep the height of the Preferences
-    dialog fitting small displays.

-  - Default to 300ppi and 1920x1080px for new documents.
-  - Default to 62px font size.
-  - Do not allow Alt+[0-9] shortcuts, they are typically reserved for
-    display switching.
-  - Icons size is now a configurable option, not a theme feature.
-    The icon size is also auto-guessed from monitor resolution now.
-  - It is now possible to have keybindings for previous/next/top/bottom
-    vectors.
-
-Tools:
-
-  - Complete the Handle Transform tool and make it available by default.
-  - Add Hue-Chroma operation/tool that operates in CIE LCH color space.
-  - Replace Color Balance, Colorize and Hue-Saturation with GEGL-based
-    filters with a custom user interface to ease future transition to
-    non-destructive editing planned for v3.2. Remove the "Image -> 
-    Tools -> Color Tools" submenu.
-  - The Move tool now shows relative coordinates when moving guides
-    and sample points.
-  - The Measure tool has better digit precision now (before that, at
-    4000 PPI, up to 7 pixels would show up as 0 mm, then at 0.1 mm from
-    the 8th pixel etc.).
-  - All paint tools now display the angle (relatively to the horizontal
-    line, centered on previously drawn position) alongside distance in
-    status bar when straight line constraining (holding shift when
-    painting).
-  - Performance of the Fuzzy Select and the Bucket Fill tool has been
-    improved.
-  - The Fuzzy Select and the Bucket Fill tool now can select colors by
-    CIE L, C, and H.
-  - Unclutter transform tools: default to "no grid", hide the original
-    layer during the interactive transform (except for the Flip tool).
-  - Make the Warp Transform tool faster, add more options, use
-    the linear sampler to ensure crisp lines after an erase.
-  - Select by Color and Color Picker tools work now correctly in color
-    spaces other than sRGB.
-  - Free Select tool now waits for Enter being pressed to confirm
-    selection, which enables you to tweak positions of polygonal selection.
-  - Color Picker doesn't snap to anything when picking colors anymore,
-    always draws the outline of the averaged region (not only while the
-    mouse is being pressed), and supports arbitrary range of values
-    regardless of the actual image color precision.
-  - Color Picker now displays pick position (also visible in the
-    Sample Points dialog now), as well as values in CIE LAB and CIE LCH.
-  - Uncommitted selection by the Intelligent Scissors tool is not
-    discarded on tool change anymore.
-  - For Intelligent Scissors, GIMP now checks whether the first and the
-    last isegments are distinct before closing the curve.
-  - Flip tool: add Clipping option to the flip tool. Add support for
-    reflecting across guides: when clicking on a guide while using the
-    Flip tool, reflect the active item across the guide, rather than
-    around its center.
-
-Painting:
-
-  - The Smudge tool now has a Flow control that allows mixing in both
-    constant and gradient color while smudging. There's another new
-    option to never decrease alpha of existing pixels while smudging
-    in the tools options now as well.
-  - Rulers, scrollbars, and the Navigation dialog follow canvas
-    rotation now.
-  - Canvas rotation is now snappier in certain cases.
-  - For bitmap brushes, GIMP now caches hardness and disables dynamic
-    change of hardness to improve painting performance. Bitmap brushes
-    also don't get clipped anymore, when hardness is less than 100.
-  - Allow painting on transparent layers with modes other than normal.
-  - Add a specialized convolution algorithm for the hardness blur
-    to make it faster.
-  - Make the Force option insensitive for the Pencil tool.
-  - Add new "Pressure Size" dynamics.
-
-File Formats:
-
-  - Make the default raw (DSLR) image importer configurable.
-  - Add RawTherapee plug-in to pre-process various raw (DSLR) images,
-    RawTherapee v5.2 is the minimum requirement.
-  - Add new file-raw-placeholder plug-in that registers itself for
-    loading all raw formats from file-raw/file-formats.h, but does
-    nothing except returning an error message pointing to darktable
-    and RawTherapee.
-  - Add native WebP loader/exporter with support for ICC profiles,
-    animation, metadata.
-  - The TIFF loader will not generate warnings about private tags
-    anymore.
-  - Handle linear gamma PNG files correctly, provide a combo box for
-    specifying PNG bit depth / variant at exporting time.
-  - Add support for linear burn, linear light, vivid light, pin light,
-    and hard mix layer modes in PSD (importing and exporting).
-  - Load PSD files with layers which contain additional information
-    with a length that is not divisible by 4.
-  - Add support to import/export layer color tags from/to PSD files.
-  - Optionally convert all imported (not XCF) images to 32-bit linear
-    floating point, and optionally add a little noise in order to
-    distribute the colors minimally.
-  - Optionally add alpha channel to layers of imported images
-    (configurable in Preferences > Import).
-  - Support writing PNM files with 16-bit image precision.
-  - Improve support for PCX files:
-    * saving 1bpp and 4bpp images (according to palette size).
-    * loading 2bpp, 2 planes/1bpp, 3 planes/1bpp and 4bpp images.
-    * non-Black&White monochrome PCX files (any 2 colors according to
-      the palette).
-  - Add support for exporting multi-page PDF from image layers, with
-    optional reversed order.
-  - Add RLE support for RGB565 in file-csource.
-
-Metadata:
-
-  - Add new metadata viewer that uses Exiv2 to display Exif, XMP, IPTC,
-    and DICOM metadata (the latter is displayed on the XMP tab).
-  - Add metadata editor that supports adding/editing writing XMP, IPTC,
-    DICOM, and GPS/Exif metadata, as well as loading/exporting metadata
-    from/to XMP files.
-
-Printing:
-
-  - Print resolution can now be reset to defaults, new values for the
-    same image is actually used now without reloading the image.
-
-Plug-ins:
-
-  - The Screenshot plug-in now assigns either monitors profile or
-    converts to sRGB.
-  - The Screenshot plug-in can now take screenshots of a single window
-    and include the mouse pointer in the same time (if the desktop/OS
-    allows it).
-  - Port smooth-palette to GEGL.
-  - Enhance the raw (not the digital negative) files plugin:
-    introduce exporting settings and remember them across sessions,
-    make the plugin invokable non-interactively, and more.
-  - Plug-ins can now be installed into first level directories of a
-    plug-ins/ folder. This is in particular to avoid the "DLL hell"
-    with shared libraries installed by a plug-in, interfering with other
-    unrelated plug-ins. The entry point file has to be named the same as
-    the directory (minus extension).
-
-Filters:
-
-  - Add GEGL-based filters: Neon (Edge detection), Wavelet Decompose,
-    Image Gradient, Symmetric Nearest Neighbor, Extract Component,
-    RGB Clip, Simple Linear Iterative Clustering, Waterpixels, Spiral.
-  - Add rotate/flip buttons to the Convolution Matrix filter's GUI

+                   GNU Image Manipulation Program
+                         2.10 Stable Branch
+                   ------------------------------
+
+This is the stable branch of GIMP. Unlike earlier stable branches,
+we do allow some new features here, if they are not too invasive.
+Otherwise, this branch is only for bug-fixes.
+
+
+Overview of Changes from GIMP 2.10.0 RC1 to GIMP 2.10.0
+=======================================================
+
+Core:
+
+  - CLI option --show-playground visible in --help.
+  - Sample point dockable now works with more than 4 sample points.
+  - Various warnings removed, multi-threading officially not
+    "experimental" anymore…
+  - Various fill and fade operations now use the current paint composite
+    mode, allowing for instance filling to paint over transparent areas.
+  - Default layer and paint modes are now Normal (instead of Legacy).
+  - Be smarter about layer modes for new layers.
+  - Get rid of the remaining places that were using the NORMAL_LEGACY
+    mode by default (painting, some more).
+  - Improve painting speed even more by even more evil C++.
+  - Flipping drawables is much faster because it's now working
+    tile-by-tile.
+  - Gradient rendering is now much faster, using a cache.
+
+Plug-ins:
+
+  - Ripple plugin removed, compat PDB-API "plug-in-ripple" added
+    instead.
+
+PDB:
+
+  - New procedure: gimp-item-transform-translate.
+  - Make gimp-item-transform-* transform linked items too.
+  - Deprecate gimp-color-balance and gimp-layer-translate.
+
+Assets / Resources:
+
+  - New "Fun" category for brushes (moving the "Pepper" there, which
+    also gets improved resolution), and adding Wilber and GEGL brushes.
+  - "Structure" brush obsoleted.
+  - 5 new and more serious brushes.
+
+Translations:
+
+  - 6 translations were updated: Catalan, Danish, Finnish, Korean,
+    Polish, Swedish.
+
+
+Overview of Changes from GIMP 2.10.0 RC1 to GIMP 2.10.0 RC2
+===========================================================
+
+Core:
+
+  - Symmetries are now preserved in XCF files (saved as image parasites).
+  - New runtime option --show-debug-menu in order to make the File >
+    Debug menu visible.
+  - Do not show invisible actions in search dialog.
+  - Do not dither image mask and channels for imported images.
+  - Various optimizations for painting and display (WIP), including
+    parallelized painting code.
+  - New "Misc" group to the Dashboard dock, with currently only a
+    "Mipmapped" field showing the total size of processed mipmapped
+    data.
+  - Plug-ins debugging on crashes through --stack-trace-mode CLI option
+    improved to handle more case.
+  - Fix selection -> channel -> selection roundtrips by never doing
+    any gamma conversion when converting between an image's selection,
+    channels, masks. Also, make all channels linear in all images with
+    >8bit.
+
+Libgimp:
+
+  - New group "drawable_edit" which contains all functions from "edit"
+    that are not cut/copy/paste. The new functions have much less
+    arguments and take them from the context instead. The respective
+    functions in "edit" have been deprecated.
+  - New functions in "context" to configure aspects of gradient
+    drawing, and to set the built-in gradients (the new gradient
+    function in "drawable_edit" doesn't have a parameter for the
+    gradient type any longer).
+
+User interface:
+
+  - Lighter and Darker themes removed for now, Light and Dark themes
+    rewritten from scratch to get rid of various usability issues and
+    glitches. Only Gray theme from previous set kept as-is.
+  - New GimpToolGyroscope on-canvas control, currently used for
+    the Panorama Projection filter. The widget provides on-canvas
+    interaction for 3D rotation (yaw, pitch, roll).
+
+Configurability:
+
+  - In Preferences > Dialog Defaults, new section "Filter Dialogs"
+    created to customize various common features of filters, such as
+    recent settings and advanced color options.
+  - Do not default to last used filter settings, but allow this behavior
+    in Preferences > Dialog Defaults, with checkbox "Default to the last
+    used settings".
+
+Tools:
+
+  - Color used in the Smudge tool is now added to the color history.
+  - "Blend" tool renamed to much more consistent "Gradient" tool.
+    Also it can now work in linear RGB matching capabilities CSS/SVG
+    specification without gamma-errors in color blending and CIE Lab
+    which in addition keeps a perceptual graylevel.
+
+Assets / Resources:
+
+  - Adding 4K UHD in document templates (and fixing 4K DCI).
+
+Building:
+
+  - New --enable-bundled-mypaint-brushes option in configure to decide
+    whether to use the configure-time installation path of MyPaint
+    brushes, or use a path relative to GIMP installation prefix
+    (typically for bundled binaries, such as on Windows or macOS).
+  - Detect freetype2 using pkg-config (`freetype-config` is on its way
+    out in various distributions apparently).
+  - Appdata now installed to $PREFIX/share/metainfo/
+
+Translations:
+
+  - 8 translations were updated: Arabic, Catalan, Chinese, French, Italian,
+    Polish, Russian, Swedish.
+
+
+Overview of Changes from GIMP 2.9.8 to GIMP 2.10.0 RC1
+======================================================
+
+Core:
+
+  - New dashboard dockable: shows the current GEGL cache and swap sizes
+    and CPU usage and active time, and their recent history. It has
+    options to control the update rate and history duration of the data,
+    and an option to warn (by raising/blinking the dialog) when the swap
+    size approaches its limit.
+  - Make the selection boundary detection the same as 2.8.
+  - The environment variable GIMP_DEBUG can now be set to "list-all" to
+    display available debug domains. Non-recognized flags will also
+    trigger the debug flag list output.
+  - Improve migration from 2.8 to 2.10 by recursively migrating
+    configuration files (up to 5 levels, to protect from recursive
+    symbolic links).
+  - Mark legacy plug-ins and scripts in menus.
+  - Enable "save-tool-options" and "save-device-status" by default,
+    it's the expected behavior these days.
+  - GIMP doesn't warn any more for unknown darktable XMP metadata. We now
+    register the corresponding namespace.
+  - Adding settings for metadata export handling in "Image Import &
+    Export" page of Preferences. By default, the settings are checked,
+    but you can uncheck them (in particular since metadata can often
+    contain a lot of sensitive information).
+  - Splash image now scaled down to maximum 1/2 of the screen area. This
+    will allow to ship a big splash image which will be visible on all
+    type of screens, whichever low or high resolution. Vector splash
+    images are scaled both up or down to have them always at ideal size.
+  - Brightness-Contrast, Curves, Levels and Threshold are now available
+    in "Repeat last" history.
+  - Improve action history to not show newly excluded actions (which
+    were already in our history from before the exclusion).
+  - Use GEGL for transform-tools preview, allowing faster and more
+    accurate previews.
+  - Re-arrange color models in the Color dock (WIP).
+  - New debug tool and infrastructure to handle WARNING and CRITICAL
+    errors, as well as fatal errors (crashes), raising a pop-up with all
+    version information on GIMP and its main dependencies, as well as
+    the error message and backtraces, and encouraging people to make bug
+    reports.
+  - Support layer masks on layer groups.
+  - GIMP now attempts to backup unsaved images when it crashes. Then at
+    next startup, it will suggest to recover the salvaged images. Image
+    recovery is not 100% guaranteed.
+  - New gimp_spawn_async() function uses vfork() to help avoid hanging
+    during a fork process, currently used for plug-ins.
+  - Dock color picker is now color-managed on macOS.
+
+Libgimp:
+
+   - New gimp_export_exif(), gimp_export_xmp() and gimp_export_iptc()
+     functions returning the creator choice regarding default handling
+     for metadata export (as set in the Preferences).
+   - GIMP Protocol version incremented.
+   - New gimp_get_pdb_status() to return the status of the last PDB
+     call. This is needed for plug-ins which depend on other plug-ins'
+     procedures. If for instance, a second-level plug-in is interrupted
+     interactively, we don't want to process this as an error but as a
+     cancellation.
+   - New gimp_stack_trace_available(), gimp_stack_trace_print() and
+     gimp_stack_trace_query() for debugging.
+   - Use gegl:distance-transform in gimp_edit_blend() implementation
+     making it much faster for all GRADIENT_SHAPEBURST_* gradient types.
+     Legacy gimp:shapeburst operation has been deleted.
+   - New gimp_context_get_distance_metric() and
+     gimp_context_set_distance_metric() for distance metric used in
+     gimp_edit_blend() (and future usage).
+
+GUI and Usability:
+
+  - New icons: "gimp-attach", "gimp-color-space-linear",
+    "gimp-color-space-perceptual", "gimp-color-temperature",
+    "gimp-dashboard", "gimp-detach", "gimp-tool-desaturate",
+    "gimp-tool-exposure", "gimp-tool-shadows-highlights".
+  - Switching between linear and perceptual (gamma-corrected) spaces
+    in the Histogram dialog is easier now: two buttons instead of one
+    two-way button where current state was difficult to understand.
+  - Shorten color channel labels in the color frame (color picker tool,
+    sample point editor…) with conventional 1 or 2-letter abbreviations,
+    and split coordinates on 2 lines.
+  - We now switch to "Huge" icons by default when the display pixel
+    density is over 250 PPI (used to be 300 PPI).
+  - Improve action history sorting: items climb up the list faster,
+    while top items retain their relative position longer.
+  - Extend action search "initialism": Extend initialism-based search
+    (e.g.: "gb" for "Gaussian Blur"), by matching arbitrarily-long
+    initialisms, and by allowing partial matches (with lesser priority).
+  - Values in the GimpNumberPairEntry widgets can now be cleared by clicking
+    an icon.
+  - Transform Grid controller is now available for custom UIs of GEGL
+    operations (currently used for Recursive Transform op).
+  - New GimpHighlightableButton widget is used to draw attention to buttons
+    in certain cases. Currently used for anchoring and removing floating
+    selections.
+  - Composite modes were renamed to be more descriptive, as follows:
+    Source Over       =>  Union
+    Source Atop       =>  Clip to Backdrop
+    Destination Atop  =>  Clip to Layer
+    Source In         =>  Intersection
+
+Configurability:
+
+  - Wilber logo in the toolbox can now be disabled via Preferences
+    (the Toolbox page).
+
+Tools:
+
+  - "Link brush size with canvas zoom" paint option becomes "Lock brush
+    to view" to make a brush invariant in display space whichever
+    scaling, rotation, and reflection.
+  - Blend tool now displays the line length (in current shell unit and
+    with ideal digit accuracy) and angle in the status bar.
+  - Constrain line angles in display space: all tools which have a line
+    constraint feature (for instance blend tool, paint tools in line
+    mode, etc.) will now do so relatively to the display, allowing you
+    to rotate the canvas in order to constrain to any arbitrary angle.
+  - Levels and Curves can now work on linear light data, the toggles are
+    at the top of respective dialogs, right next to linear/log toggles
+    for the histogram.
+  - Blend tool now has a distance metric option to determine how
+    distances are computed (Euclidean, Manhattan or Chebyshev
+    distances).
+
+Filters:
+
+  - New GEGL-based Shadows-Highlights filter now available in the Colors
+    menu. The implementation is based on the code from darktable.
+
+Plug-ins:
+
+  - Screenshot with the generic Freedesktop API has been implemented. It
+    is meant to replace all desktop environment specific APIs eventually
+    but needs to get reasonable features first. Therefore currently
+    GNOME/KDE and X11 implementations still have priority.
+  - qbist ported to GEGL and float.
+  - Colors for the standard output and standard error texts in the
+    Python console are now themeable, mapping respectively to normal
+    text and insensitive text colors for the "python-fu-console" widget.
+    We updated the default colors a bit for our themes. If this is not
+    good enough (for instance, if one has a specific type of color
+    blindness), at least it is now possible to create a custom theme
+    adapted to one's needs.
+  - PSD export now happens with progress bar update for feedback.
+  - Win32 Screenshot improved to handle hardware-rendered software and
+    multi-monitor displays.
+
+File formats:
+
+  - Fix various vulnerabilities in file plug-ins: GBR (CVE-2017-17784),
+    PSP (CVE-2017-17787 and CVE-2017-17789), TGA (CVE-2017-17786) and
+    FLI (CVE-2017-17785).
+  - Fix WebP export under Windows.
+  - No more max dimension limitation for X cursors. We still warn when
+    cursor size is over a max limit for X bitmap cursors, but we don't
+    clamp anymore on export.
+  - JPEG, PNG, TIFF and WebP export plug-ins updated to honor creator's
+    default choice regarding metadata handling.
+  - Fix GIH brushes using different-sized layers.
+  - RGBE (Radiance HDR) format files can now be imported and exported.
+  - JPEG2000 loading now done via OpenJPEG library and supports any bit
+    depth (over 32-bit per channel will be clamped to 32-bit and
+    non-multiple of 8-bit will be promoted, for instance 12-bit will end
+    up as 16-bit per channel in GIMP). JPEG 2000 codestream also
+    supported and displays a dialog asking for the color space (whereas
+    JPEG 2000 image color space are auto-detected).
+    JPEG 2000 images or codestream in YCbCr, xvYCC and CMYK color spaces
+    are converted to sRGB images upon loading.
+
+Building:
+
+  - poppler and poppler-data now hard dependencies. PDF import is
+    considered a granted feature nowadays and fallbacking to the
+    Postscript plug-in was bad experience.
+  - move PDB generation and sources to toplevel/pdb.
+  - New configure option `--enable-windows-installer` to generate the
+    necessary files for the installer translations during the build.
+  - Improve POTFILES generation for po-*/ directories.
+  - Require glib >= 2.54.2.
+  - New dependency to mypaint-brushes-1.0 for stable MyPaint brushes
+    available at installation.
+  - AppStream ID renamed from gimp.desktop to org.gimp.GIMP following
+    current convention.
+  - Require fontconfig >= 2.12.4. Lower versions are particularly a
+    problem on Win32, where many cache update failure were reported to
+    us, resulting in very slow startup and close-up (and not only the
+    first time, but every time).
+
+Translations:
+
+  - Windows installer now localized with gettext.
+  - String freeze has started and GIMP received updates from:
+    Basque, Brazilian Portuguese, Catalan, Chinese (Taiwan), Danish,
+    Esperanto, French, German, Greek, Hungarian, Icelandic, Italian,
+    Japanese, Latvian, Polish, Russian, Serbian, Slovenian, Spanish,
+    Swedish, Turkish.
+
+
+Overview of Changes from GIMP 2.9.6 to GIMP 2.9.8
+=================================================
+
+Core:
+
+  - The default brush is now "Hardness 050".
+  - Verbose version (command line: gimp -v) now displays C compiler
+    information.
+  - Transform tools don't commit identity transformation anymore.
+  - Manual language can now be selected amongst all installed manuals,
+    which is particularly interesting when no GIMP manuals are available
+    in your GUI language. This will be proposed by default when a manual
+    is not installed for the GUI language (alongside the possibility to
+    read online) and the choice can be edited in preferences.
+  - The statusbar now blinks on warnings and errors.
+  - Paste in Place, available for regular clipboard and named buffers,
+    allows pasting contents of either the clipboard a named buffer at the
+    exact coordinates it was copied from.
+  - Color Picker should now work on KDE/Wayland.
+  - Color Picker now reads values under cursor in local windows making
+    it work at least inside GIMP Windows on Wayland platforms with no
+    color-picking capabilities (for instance GNOME/Wayland) yet.
+  - OpenCL is now disabled by default. Depending on graphics cards and
+    drivers, OpenCL acceleration is often slower than multi-threaded
+    implementation, and can also sometimes be "glitchy".
+  - Now possible to open a locally-installed manual different from the
+    GUI localization. The manual language choice can be customized
+    through preferences when several manuals are installed. If no manual
+    language has been selected already and no manual for current GUI
+    localization is available, choice of help language will be proposed
+    at first call to the manual.
+
+Configurability:
+
+  - Keybindings now possible for previous/next/top/bottom channel.
+
+Usability:
+
+  - The spinscale widget now highlights vertical parts of the slider
+    section differently to hint that position of cursor above the widget
+    matters. When changing values in the lower step section, the pointer
+    will be wrapped around the screen so that you could continue adjusting
+    the value without interruptions.
+  - Canvas rotation and flip information is now visible in the status
+    bar (as angle value and flip icon). Clicking on these canvas status
+    will respectively raise the "Select Rotation Angle" dialog or unflip
+    the canvas.
+  - Use abbreviated versions for long layer mode names. In particular,
+    replace the "(legacy)" suffixes with "(l)" in the abbreviated
+    versions, still showing the unabbreviated names in the full list.
+
+Tools:
+
+  - Blend tool now features on-canvas gradient editing: adding, shifting,
+    removing color stops, shifting midpoints and converting them to color
+    stops, assignging colors to color stops, changing blending type
+    for midpoints. Additional options: 'Instant mode' (active before you
+    start blending) to support the old workflow where you can't edit color
+    stops before applying the gradient fill, and 'Modify active gradient'
+    which allows changing user-writable gradients directly rather than
+    creating copies of them. Moreover, custom gradient is now saved
+    and restored across sessions.
+  - All transform tools: it makes no difference now whether a modifier is
+    pressed before of after mouse button press/release.
+  - Free Select tool selection can now be committed with double click as
+    well (only through Enter key before). This allows smoother workflows
+    on some setups, and in particular when no keyboard is available
+    (e.g. tablet-like computers).
+  - Layer group children now inherit the color tags of the parent by
+    default, unless specific color tags are assigned. Inherited color
+    tags show in a less saturated color than assigned ones.
+
+Painting:
+
+  - When copying a generated brush, GIMP now copies its 'Spacing' property.
+  - Rename "Wheel" dynamics labels as "Wheel/Rotation". It turns out
+    that Wacom Art Pen and Airbrush pen use the same axis for barrel rotation
+    and wheel scrolling respectively. Therefore they already work in GIMP.
+    "Unhide" the feature with more obvious labels.
+
+Color management:
+
+  - Use babl to convert between profiles if possible.
+
+Display filters:
+
+  - New 'Clip Warning' display filter to show underexposed and overexposed
+    values. Target values below 0 and above 1.0, hence it only works on
+    16/32 bit per channel float images (such as EXR and TIFF).
+  - Display filters now operate in unbounded sRGB rather than in monitor
+    color space.
+
+Plug-ins:
+
+  - Fix finding raw loaders on Windows/macOS.
+  - Screenshot for KDE/Wayland has been implemented (full-screen and
+    window screenshots only; rectangular area screenshots need
+    implementation on the KDE side).
+  - Screenshot can now add a delay between window pick/rectangular
+    area selection and the actual shot, but only in platforms supporting
+    the feature.
+
+File formats:
+
+  - PSD:
+    - Fix mask position when opening/exporting.
+    - Fix active layer selection during loading.
+    - Fix potential group-layer naming conflict during loading.
+    - Fix missing some attributes loading empty layers.
+    - Fix reading files with deeply nested layer groups.
+    - Load and save layer group expanded state.
+    - Improve layer opacity loading/saving.
+  - PDF: password-protected files can now be imported.
+  - HGT: Digital Elevation Model data from NASA/NIMA can now be loaded,
+    both SRTM-1 (1 arc-second) and SRTM-3 (3 arc-seconds).
+
+Filters:
+
+  - Update GEGL-based filter Wavelet Decompose:
+    - Add an option to keep the decomposition in a layer group.
+    - Add an option to add layer mask to each scales layers.
+    - Do not use 'New from visible' because it produces unexpected
+      results; replaced by succession of layer copy and merge down.
+
+PDB:
+
+  - Add file-pdf-load2 API to load password-protected and/or multi-page
+    PDF files.
+  - Add file-hgt-load to load HGT files, with an argument to select between
+    SRTM-1 and SRTM-3 types.
+
+Translations:
+
+  - Updated: Catalan, Croatian, Galician, German, Greek, Hungarian,
+    Icelandic, Indonesian, Italian, Polish, Russian, Spanish.
+
+Building:
+
+  - Require LittleCMS >= 2.8.
+  - Initial docker-based build environment for GIMP now available.
+  - Warn against use of GCC 7.2 which has a bug breaking GIMP.
+  - An official flatpak stable package is now available on flathub.

+
+Overview of Changes from GIMP 2.9.4 to GIMP 2.9.6
+=================================================
+
+Core:
+
+  - Make it possible to use multithreading in GEGL and raise max amount
+    of threads to 64. Given how unstable this feature is, any value
+    above 1 should be currently treated as a step inside an industrial
+    microwave oven with the on/off switch on the outside.
+  - New clipboard implementation allows copying/pasting layers and
+    layer groups.
+  - Color tags simplify managing large projects with a lot of layers
+    and layer groups.
+  - The Mouse Pointer dialog and colors applied to images are now
+    color-managed.
+  - Gamma and precision selectors for newly created images.
+  - Never dither when converting to a higher bit depth, or to anything
+    more than 16 bits; don't offer dithering options in these cases.
+  - Default to linear TRC when converting to 16-bit float.
+  - Pre-initialize some babl-based pixel format conversion routines
+    at start-up to decrease the initial lazy intialization cost for
+    some interactions.
+  - Remove max size limitation of 4GB for XCF files.
+  - Support clipboard images in the clipboard brush and pattern.
+  - libgimp calls are now thread-safe.
+
+Layers and compositing:
+
+  - Layer modes' code is now refactored to separate gamma-corrected
+    variations from the linear light ones, legacy modes have been
+    preserved to support older XCF files. UI to switch between the two
+    is experimental and should be treated as a temporary design.
+  - Blending and compositing of layers are configurable separately for
+    more flexibility now, compositing can be linear TRC, perceptual TRC
+    or CIE LAB.
+  - Layer blending color space and compositing color space are
+    configurable now.
+  - Layers created from the GUI and from plug-ins now default to
+    normal mode (not normal-legacy), unless all the existing layers
+    in the image are also in legacy mode.
+  - New layer modes: linear burn, vivid light, linear light, pin light,
+    hard mix, exclusion, merge, split, luminance (rgb), pass-through
+    (for layer groups only).
+  - Make erase mode an ordinary layer/paint mode.
+  - Better performance of HSV-based layer modes.
+  - Rename "Color (HSV)" mode to "Color (HSL)" to indicate the actual
+    color space being used.
+
+On-canvas interaction changes:
+
+  - Refactor on-canvas interaction code out of some of the tools and
+    make it reusable.
+  - Update tools accordingly.
+  - Make on-canvas interaction accessible to GEGL-based filters and
+    use it in the Spiral and Supernova filters as a test case.
+
+GUI and usability:
+
+  - Easily add or remove layer masks by clicking either the layer
+    preview or a new button in the Layers dialog.
+  - Enhance the Layer Attributes dialog to provide the single UI for
+    setting layer's name, blending mode, opacity, and offset,
+    toggling visibility, link status, various locks, color tags.
+  - Add a Save As button to the “Quit GIMP” dialog and raise images
+    on click for easy checks.
+  - Allow to choose fill color when resizing layers and images.
+  - Quick Mask and Channel Attributes dialogs use the new spinscale
+    widget for the  mask opacity slider.
+  - Enable grid views of dynamics and tool presets.
+  - Allow to zoom with middle mouse button + control + drag up/down.
+  - For all paint tools, when switching to the color picker mode,
+    don't rely on the exact modifier being pressed or released. Instead,
+    check if only the right modifier is pressed after *each* modifier
+    change, and switch to color picking if it is.
+  - On startup, GIMP checks for duplicate accelerators in menus, and
+    removes duplicates.
+  - Standard (Freedesktop) and GTK+ icons can now be set by the icon
+    theme for a fully consistent style.
+  - Many new icons.
+  - Toolbox buttons do not grab focus anymore, which used to break
+    usage of the Tab key and other canvas-related shortcuts after
+    changing tools with a pointing device click.
+  - Delete Layer/Channel/Path are consistently the last option in
+    respective dialogs now.
+  - Extend the text along the tangent of the last path stroke, when
+    the length of the path is shorter than the width of the text to be
+    warped.
+  - Allow to toggle the histogram dialog between gamma and linear.
+  - New 'Colors -> Linear Invert' command to provide radiometrically
+    correct color inversion.
+  - Quit dialog now exits when all the images in the list have been
+    saved.
+  - The built-in error dialog now displays errors outputted by GEGL.
+  - Shift-clicking the visibility icon of a layer in a layer group now
+    toggles its exclusive visibility within this layer group.
+
+Color selection and management:
+
+  - Add the profile import policy to Preferences -> Import.
+  - Color management for GEGL-based filters is expensive, so it's off
+    by default for now, and options are hidden by default too.
+  - Add LCH color selector, with support for gamut checking.
+  - Default to magenta for out-of-gamut color.
+  - Make all script-fu color buttons color-managed.
+
+Configurability:
+
+  - Remember settings of many dialogs across sessions.
+  - New Interface / Dialog Defaults page in the Preferences dialog to
+    control defaults values of various dialogs.
+  - Settings on some individual pages of the Preferences dialog can be
+    reset separately now.
+  - Vertical scrollbar added to keep the height of the Preferences
+    dialog fitting small displays.
+  - Allow mouse to optionally configure tablet devices
+  - Allow creating shortcuts containing the Cmd key + mouse wheel events.
+  - Default to 300ppi and 1920x1080px for new documents.
+  - Default to 62px font size.
+  - Do not allow Alt+[0-9] shortcuts, they are typically reserved for
+    display switching.
+  - Icons size is now a configurable option, not a theme feature.
+    The icon size is also auto-guessed from monitor resolution now.
+  - It is now possible to have keybindings for previous/next/top/bottom
+    vectors.
+
+Tools:
+
+  - Complete the Handle Transform tool and make it available by default.
+  - Add Hue-Chroma operation/tool that operates in CIE LCH color space.
+  - Replace Color Balance, Colorize and Hue-Saturation with GEGL-based
+    filters with a custom user interface to ease future transition to
+    non-destructive editing planned for v3.2. Remove the "Image -> 
+    Tools -> Color Tools" submenu.
+  - The Move tool now shows relative coordinates when moving guides
+    and sample points.
+  - The Measure tool has better digit precision now (before that, at
+    4000 PPI, up to 7 pixels would show up as 0 mm, then at 0.1 mm from
+    the 8th pixel etc.).
+  - All paint tools now display the angle (relatively to the horizontal
+    line, centered on previously drawn position) alongside distance in
+    status bar when straight line constraining (holding shift when
+    painting).
+  - Performance of the Fuzzy Select and the Bucket Fill tool has been
+    improved.
+  - The Fuzzy Select and the Bucket Fill tool now can select colors by
+    CIE L, C, and H.
+  - Unclutter transform tools: default to "no grid", hide the original
+    layer during the interactive transform (except for the Flip tool).
+  - Make the Warp Transform tool faster, add more options, use
+    the linear sampler to ensure crisp lines after an erase.
+  - Select by Color and Color Picker tools work now correctly in color
+    spaces other than sRGB.
+  - Free Select tool now waits for Enter being pressed to confirm
+    selection, which enables you to tweak positions of polygonal selection.
+  - Color Picker doesn't snap to anything when picking colors anymore,
+    always draws the outline of the averaged region (not only while the
+    mouse is being pressed), and supports arbitrary range of values
+    regardless of the actual image color precision.
+  - Color Picker now displays pick position (also visible in the
+    Sample Points dialog now), as well as values in CIE LAB and CIE LCH.
+  - Uncommitted selection by the Intelligent Scissors tool is not
+    discarded on tool change anymore.
+  - For Intelligent Scissors, GIMP now checks whether the first and the
+    last isegments are distinct before closing the curve.
+  - Flip tool: add Clipping option to the flip tool. Add support for
+    reflecting across guides: when clicking on a guide while using the
+    Flip tool, reflect the active item across the guide, rather than
+    around its center.
+
+Painting:
+
+  - The Smudge tool now has a Flow control that allows mixing in both
+    constant and gradient color while smudging. There's another new
+    option to never decrease alpha of existing pixels while smudging
+    in the tools options now as well.
+  - Rulers, scrollbars, and the Navigation dialog follow canvas
+    rotation now.
+  - Canvas rotation is now snappier in certain cases.
+  - For bitmap brushes, GIMP now caches hardness and disables dynamic
+    change of hardness to improve painting performance. Bitmap brushes
+    also don't get clipped anymore, when hardness is less than 100.
+  - Allow painting on transparent layers with modes other than normal.
+  - Add a specialized convolution algorithm for the hardness blur
+    to make it faster.
+  - Make the Force option insensitive for the Pencil tool.
+  - Add new "Pressure Size" dynamics.
+
+File Formats:
+
+  - Make the default raw (DSLR) image importer configurable.
+  - Add RawTherapee plug-in to pre-process various raw (DSLR) images,
+    RawTherapee v5.2 is the minimum requirement.
+  - Add new file-raw-placeholder plug-in that registers itself for
+    loading all raw formats from file-raw/file-formats.h, but does
+    nothing except returning an error message pointing to darktable
+    and RawTherapee.
+  - Add native WebP loader/exporter with support for ICC profiles,
+    animation, metadata.
+  - The TIFF loader will not generate warnings about private tags
+    anymore.
+  - Handle linear gamma PNG files correctly, provide a combo box for
+    specifying PNG bit depth / variant at exporting time.
+  - Add support for linear burn, linear light, vivid light, pin light,
+    and hard mix layer modes in PSD (importing and exporting).
+  - Load PSD files with layers which contain additional information
+    with a length that is not divisible by 4.
+  - Add support to import/export layer color tags from/to PSD files.
+  - Optionally convert all imported (not XCF) images to 32-bit linear
+    floating point, and optionally add a little noise in order to
+    distribute the colors minimally.
+  - Optionally add alpha channel to layers of imported images
+    (configurable in Preferences > Import).
+  - Support writing PNM files with 16-bit image precision.
+  - Improve support for PCX files:
+    * saving 1bpp and 4bpp images (according to palette size).
+    * loading 2bpp, 2 planes/1bpp, 3 planes/1bpp and 4bpp images.
+    * non-Black&White monochrome PCX files (any 2 colors according to
+      the palette).
+  - Add support for exporting multi-page PDF from image layers, with
+    optional reversed order.
+  - Add RLE support for RGB565 in file-csource.
+
+Metadata:
+
+  - Add new metadata viewer that uses Exiv2 to display Exif, XMP, IPTC,
+    and DICOM metadata (the latter is displayed on the XMP tab).
+  - Add metadata editor that supports adding/editing writing XMP, IPTC,
+    DICOM, and GPS/Exif metadata, as well as loading/exporting metadata
+    from/to XMP files.
+
+Printing:
+
+  - Print resolution can now be reset to defaults, new values for the
+    same image is actually used now without reloading the image.
+
+Plug-ins:
+
+  - The Screenshot plug-in now assigns either monitors profile or
+    converts to sRGB.
+  - The Screenshot plug-in can now take screenshots of a single window
+    and include the mouse pointer in the same time (if the desktop/OS
+    allows it).
+  - Port smooth-palette to GEGL.
+  - Enhance the raw (not the digital negative) files plugin:
+    introduce exporting settings and remember them across sessions,
+    make the plugin invokable non-interactively, and more.
+  - Plug-ins can now be installed into first level directories of a
+    plug-ins/ folder. This is in particular to avoid the "DLL hell"
+    with shared libraries installed by a plug-in, interfering with other
+    unrelated plug-ins. The entry point file has to be named the same as
+    the directory (minus extension).
+
+Filters:
+
+  - Add GEGL-based filters: Neon (Edge detection), Wavelet Decompose,
+    Image Gradient, Symmetric Nearest Neighbor, Extract Component,
+    RGB Clip, Simple Linear Iterative Clustering, Waterpixels, Spiral.
+  - Add rotate/flip buttons to the Convolution Matrix filter's GUI
+    to rotate/flip the matrix.
+  - For GEGL-based filters, use a new metadata language to dynamically
+    control UI attributes based on context (e.g. auto-disable
+    unapplicable options).
+  - Allow filter actions to have hardcoded default operation settings
+    by encoding them directly in the string attached to all filter
+    actions.
+
+Color Palettes:
+
+  - Merge Palettes command is available for multiple selected color
+    palettes now.
+
+Assets / Resources:
+
+  - Some basic presets are available for the Crop tool now: 2x3,
+    3x4, 16:10, 16x9, and square.
+  - Documents templates have been updated and now feature popular,
+    contemporary document presets for both print and digital media.
+
+PDB:
+
+  - Rename *-paste-as-new to *-paste-as-new-image.
+  - Add PDB API for layer blend space, compositing space, and
+    compositing mode.
+
+Build:
+
+  - Depend on LCMS2.7+ now, because earlier LCMS2 releases caused
+    problems with certain GIMP blend modes.
+  - Depend on libpng 1.6.25+ to avoid warnings about known incorrect
+    sRGB profiles, also avoid various vulnerabilities.
+  - Depend on glib-networking now for HTTPS support.
+  - Depend on librsvg 2.40.6 which fixes rendering bugs.
+  - Add a flatpak-builder manifest.
+
+OS-specific changes:
+
+  - Help browser launches on macOS now.
