[Gimp-developer] ANNOUNCE: GIMP 2.10.0-RC2 released

[Michael Natterer <mitch gimp org>]

Hi,

We just released the second release candidate on the way
to the final GIMP 2.10.0 release.

This is (still!) an unstable development release and might
crash or do whatever. If you try it for work, please save
your images more often.

But please use it and report bugs, it's actually usable :)

For a complete list of changes since 2.10.0-RC1 please see the
"Changes" section below.

There is also a release announcement on www.gimp.org
with screenshots of new features:

Happy GIMPing,

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.
