We just released GIMP 2.10.10, the fifth bugfix release in
the stable 2.10 series.

As announced before, stable GIMP 2.10.x is open for new
features that are not too invasive or change the API,
and we got some good new stuff for you this time, too.

For a complete list of changes since 2.10.8 please see the

Overview of Changes from GIMP 2.10.8 to GIMP 2.10.10


 - Add gimp-scratch allocator, a fast memory allocator (on the order
   of magnitude of alloca()), suitable for small (up to a few 
   megabytes), short-lived (usually, bound to the current stack-
   frame) allocations.
   Unlike alloca(), gimp-scratch doesn't use the stack, and is 
   therefore safer, and will also serve bigger requests, by falling-
   back to malloc().
 - In gimp_drawable_transform_buffer_affine(), avoid modifying the
   clipping mode when transforming layer masks, since this function
   is used (among other things) to transform layer masks together with
   their layer, in which case they should use the same clipping mode
   as the layer. This fixes a regression introduced by commit  
   2ae823ba, causing layer masks to be transformed with a mismatched 
   clipping mode during layer transforms, leading to discrepencies 
   between the transformed layer and the transformed mask.
 - Moved swap/cache and temporary files out the GIMP user config dir 
   and added new config file substitutions ${gimp_cache_dir} and
 - Pass the GEGL tile-cache size, swap path, and thread-count to plug-
   ins as part of their config, and have libgimp set the plug-in's 
   GeglConfig accordingly upon initialization.
 - Layer groups are now rendered in bigger chunks rather than tile-by-
   tile (which used to pretty much eliminate multithreading for 
   groups), which improves the rendering speed.
 - Make saving/exporting files more robust to errors. In particular if
   an error occurs during the process (be it a bug, a memory error, or
   anything else), GIMP won't overwrite anymore any existing file with
   incomplete contents, so that you won't end up with no valid files 
   at all.
 - Fix a regression on support of various graphics tablet.
 - Remove the "Edit -> Fade..." feature: it makes GIMP use two buffers
   instead of one (east into system resources), it's broken in 2.10, 
   and we can make the UX better for filters.
 - New generic canvas modifier 'Alt + middle click' allowing to pick
   layers by clicking on pixels. The available layers will be looped
   through (starting from the upper one) while Alt key is hold and the
   picked layer name will be temporarily displayed in the status bar.
 - When clearing a channel, do nothing if the channel is already 
   empty; otherwise, align the cleared rectangle to the channel 
   buffer's tile grid, so that all affected tiles are dropped, rather 
   than zeroed.
   Furthermore, only update the affected region of the channel.
 - Brush and pattern saving logics has been moved to core code 
   (instead of plug-in).
 - Clipboard brushes and pattern can now be duplicated.
 - Parametric brushes are now 32-bit float to avoid posterization on
   large brushes.
   Note: raster brushes are still 8-bit and plug-ins only have access
   to 8-bit versions of high-precision brushes/patterns. New API will
   be required to handle high-precision data.
 - On-canvas preview while editing a color in the colormap of an
   indexed image.

User interface:

 - Enabled HiDPI/Retina support for the GTK2/OSX build, fixes blurry 
 - Add a tooltip to the "better compression" checkbox in save dialog 
   to make it clearer it does not mean that the file size is 
   necessarily smaller in every cases. In particular some best/worst 
   case are possible when an algorithm less efficient in general may 
   end up better on a particular image.
 - Add basic support for cursors with a scale factor of 2 for HiDPI
   (artwork to be updated).
 - Foreground and background color icons, as well as color history 
   will now display out-of-gamut warning on indexed images for colors
   outside of the palette, as well as on grayscale images, for non- 
   gray colors.
 - Pack color picker and hexadecimal entry on same line in Color dock.
 - Add an "Open as Image" button to the brushes dialog.


 - Attempting to transform locked layers or paint on them now results 
   in blinking around the status bar (where the warning message is 
   displayed) and around the toolbar where lock toggles are. The same 
   applies to attempting to move a selection where there is none — 
   GIMP will blink around the toolbar where the moving target (layer,
   selection, path) is chosen.
 - GIMP now allows selecting default export file type for new 
   The choice is limited to PNG, JPEG, WebP, PSD, ORA, TIFF, BMP.
 - GimpSpinScale widget now has an optional feature to constrain the
   value to integer when dragging with a pointer (even if the scale
   allows for fractional numbers), set with new function
   This is useful for settings where fractional numbers are 
   technically possible, yet most common use case are with integers 
   (such as pixel sizes, angles in degrees, etc.) so you want the 
   easy interface to be constrained. Fractional numbers are still 
   settable, for instance by keyboard edit; and arrow incrementation 
   won't drop fraction parts. This is currently only activated for 
   brush options in paint tools.


 - In scale tool, scale around center even when using numeric input.
 - New algorithm in the Bucket Fill tool when selecting the affected
   area "Fill by line art detection", based off the G'Mic algorithm 
   for "smart colorization":
   In a few words, it identifies painted pixels (either based on
   grayscale or opacity values) and tries to close line arts to allow
   filling even with not perfectly closed zones; the second step of 
   the algorithm will flood the colors under line art pixels to 
   prevent "holes" in the filling.
   It is possible to control a max size (in pixels) for the flooding,
   as well as max length of closing segments and splines.
 - The Bucket Fill tool got new interaction allowing to hold the click
   and move the mouse to fill based on several seed zones (for "Fill
   by line art detection" as well as "Fill similar colors"). You can
   now cancel the fill in progress with right click as in other tools.
 - The Bucket Fill tool now allows color picking with ctrl-click, same
   as every painting tool. It will pick either the foreground or
   background color depending on the selected Fill Type. The ctrl-alt
   modifier combination is also possible to pick the non-Fill Type
 - In the Bucket Fill tool, the Alt modifier will now switch to
   "FG color fill" when "Pattern fill" was set (instead of doing
 - In the Unified Transform tool, default to preserving aspect ratio
   when scaling up or down.
 - In the Healing tool, "Sample merged" now also work for the target
   pixels, allowing to draw in empty layers.
 - Selection by color is now parallelized, hence improving speed of 
   the Select by Color tool (and any other processing which may share 
   this piece of code now or in the future).
 - Add "Constrain handles" and "Around center" options to the
   perspective-transform tool's GUI, which are similar to the
   corresponding options of the unified-transform tool.
 - Improve color picking on indexed image to always select an indexed
   color corresponding to the picked pixel in the colormap.


 - file-pdf-save GUI now clearly indicates the order the layers will 
   be used to make multi-page PDFs.
 - Add DDS loading/exporting plug-in originally developed by Shawn 
   Kirst and Arne Reuter.
 - Rename the Guillotine plug-in to Slice Using Guides.
 - Add a new option saving a color profile when exporting PNG, JPEG, 
   TIFF. Always save it when exporting to PSD.
 - Remove the "Advanced" expanders from the PNG and TIFF export 
 - Full rewrite of the Spyrogimp plug-in with much more options and
   better interaction.
 - Indexed TIFF with alpha channel now supported.


 - Add on-canvas GUI (simple lines) for circular, linear, and zoom 
   motion blur.


 - Link to the bugtracker directly from the Help menu, also link to 
   the wiki and the roadmap. Remove the link to currently disabled


 - Windows: proper fix for libthai to stop GIMP from crashing in the
   Thai locale. 


 - Czech, Danish, French, Italian, Japanese, Marathi, Polish, Russian,
   Spanish, Swedish, Ukrainian.


 - Bumping GTK+ dependency to the micro update GTK+ 2.24.32 to handle
   several bugs on Windows (broken shortcuts on non-latin layouts and
   broken vector icons).
