Overview of Changes from GIMP 3.2.4 to GIMP 3.2.6
=================================================

Core:

  - macOS: Macbook touchpad over-sensitivity now fixed.
  - Destructive-only filter actions will be made insensitive on all
    non-raster layers (unless rasterized).
  - Windows: in release builds, we now attach our standard outputs to
    the Windows console on certain scenarios only (when there is no
    interface, or in verbose mode, or when --console-messages is set, or
    finally when there are batch commands). By default, we are back to
    how it was before GIMP 3.2.0, which is that GIMP doesn't output
    anything on native shells it was called from.
  - Fix expand from center which was failing in some cases.
  - Layers to Image Size only works for raster (or rasterized) layers.
  - Clipboard brush and pattern max size bumped to 8192 on Aarch64
    architecture too (this was changed in 3.2.0 RC2, but only for x86-64
    and PPC64).
  - Dashboard backtraces now work on Windows Aarch64 too (additionally
    to Windows x86-64).
  - No pass-through reduction on group layers with non-destructive
    filters.
  - Dashboard backtraces now work on macOS with native API without
    libbacktrace.
  - MyPaint's custom brush directory ($USERPROFILE/.mypaint) better
    retrieved on Windows.
  - XCF:
    * Visibility lock on paths is now properly saved.
    * Channel filters were not saved either.
    * XCF is bumped to version 26.
  - Clear does not affect non-raster layers, unless rasterized.
  - Improved management of plug-in pipes and process watch. In
    particular, we avoid various warnings (about empty contexts or
    broken pipes) when closing GIMP if plug-ins processes didn't end
    first or just when closing some plug-ins.
  - Stop noninteractive filters on invisible layers unless the relevant
    option is enabled in Preferences.
  - We now verify if a plug-in has been updated since last start by
    using the changed time (ctime) as fallback when the modified time
    (mtime) is 0. This is because on some environment (such as ostree,
    hence flatpak), all files mtimes are set to the UNIX epoch.
  - Various small changes or fixes were made to prepare for a potential
    GTK 4 port.
  - Cache directory on macOS is now in ~/Library/Caches/ (instead of
    ~/Library/Application Support/).
  - Added "Rotation" input for dynamics. This gives us support of the
    Wacom Art Pen 2 stylus at least.
  - Various performance improvements in text tool and font handling were
    made.
  - It is now possible to cut layer groups with a selection (which will
    cut every children, recursively), as long as every child is writable
    ("Content Lock" must not be set and the layers must be raster, or
    rasterized).

Tools:

  - Warp tool: properly show the warp cursor even when hovering other
    images from where we started warping.
  - Crop tool: do not change position of vector layers.
  - Gradient tool:
    * The non-linear blending space was always used, even
      when linear blending was requested.
    * Fixed transparent areas when the Offset is set to 100% (1.0) and
      the Repeat policy is set to Truncate.
  - Filters: clip setting was lost when editing non-destructive filters.
  - Text tool: ignore selected layer mask of a text layer when selecting
    it with the tool to edit the text contents. The layer mask still
    stays the selected item in such a case.
  - Heal tool: dark smudge at crop boundaries is fixed.
  - Color Picker tool: there was an exception ignoring Sample Merged
    option when a single layer was visible (allowing to retrieve the
    exact palette color from indexed images). This exception has been
    further restricted to the absence of filters. Sample Merged, even of
    single layer images, should return the color after filters are
    applied.
  - MyPaint Brush tool: broken initialization was sometimes triggering a
    stroke being skipped.

Graphical User Interface:

  - MyPaint brush previews are now loaded at full size instead of 48×48.
  - Alpha Component previews fixed.
  - Caret/text cursor color now specifically set in our theme to prevent
    it from being overridden by the system theme.
  - macOS:
    * Title bar color scheme now follows the chosen theme scheme.
    * Transiency of dialogs on macOS was globally broken and is now
      being worked around on a case-by-case basis.
    * Minimize button removed from various dialogs.
    * Fix dockable windows not floating.
    * GIMP's Spin buttons now respect the Cmd key.
    * Scrollbars hiding now follows the relevant macOS system setting to
      allow always showing them if requested (this is not the default),
      just like it does with supported DEs.
    * Use Cmd+` instead of Alt+Tab.
    * Modules and Units are now listed on the mac menu like in 2.10.
    * Welcome and About dialogs are redundant from the application menu
      and were removed.
    * Ctrl+F2 is used on behalf of Alt.
    * Cmd+Shift+/ opens the Help menu.
    * Ctrl+Cmd+Space opens the Emoji viewer.
    * Improve localization for menu items.
    * Fullscreen shortcut is Ctrl + Cmd + F (F11 is reserved).
    * "Windows" and "Help" menu labels are now localized.
    * Rename "Preferences" to "Settings" as is standard on this
      platform.
  - Inactive arrow color (e.g. for notebook tabs) is now defined.
  - GimpColorScale style now moved to proper CSS.
  - GEGL Graph dialog now shows error messages for the graph in full.
  - When "Reduce Animation" (or similar accessibility option) is
    requested in OS settings, our splash will display less text (bigger
    section titles only) and no progress bar.
  - Time format is now more consistently displayed on the About dialog.
  - Tooltips are now given a max width to prevent them from getting
    overly large.
  - Size entry in Scale and Print Size dialogs receive the focus by
    default as a UX enhancement.
  - Spins of Arbitrary Zoom and Rotation dialogs receive the default focus.
  - Next tip is the default focus for the Tips dialog.
  - Space and Enter activate/deactivate modules.
  - Prefer Dark Theme setting was not correctly saved when the current
    theme doesn't have a dark theme variant.
  - Canvas checkerboard is not rotated with the view anymore.
  - More theme fixes were applied.
  - Pattern thumbnails are more properly filling their area by tiling
    them when relevant.
  - Script-Fu will focus the first widget of every dialog by default,
    will make it activate the default response if it's an entry subtype,
    and will make OK the default response.
  - Various fixes specific to KDE, as well as theme fixes related to
    GIMP over KDE Breeze.
  - The "System" theme in Preferences > Themes will now be listed with
    the actual system theme's name written in between parentheses. E.g.:
    "System (Adwaita)".
  - Add accent color support to System theme on Windows and macOS.
  - Add 150% mark to Font Scaling.
  - When a system monitor profile is set, mark down its label between
    parentheses, after "Try to use the system monitor profile" text in
    Preferences.

Plug-Ins:

  - Various security bugs fixed: CVE-2026-18301, CVE-2026-18304,
    CVE-2026-18302, CVE-2026-18303, CVE-2026-18305, CVE-2026-18306,
    CVE-2026-18307, CVE-2026-18308, CVE-2026-18309, CVE-2026-62438,
    CVE-2026-62439, ZDI-CAN-29400, #16424, CVE-2026-59087,

    CVE-2026-82324, CVE-2026-82328, CVE-2026-82330, CVE-2026-82343.
    Cf.: https://gitlab.gnome.org/Teams/Releng/security/-/wikis/home#gimp
  - RawTherapee spawned from GIMP's AppImage does not crash anymore.
  - PDF: multi-page PDF are now loaded with an image size ensuring that
    all layers are visible (in case of pages of different dimensions).
  - File-Raw:
    * Minimum darktable is version 5.6 (the relevant changes
      happened on darktable side).
    * New versions of RawTherapee are now detected as well.
  - Mail: add Windows MAPI support.
  - NL Filter: now made sensitive on layers with alpha channel too.
  - Python Console: Tab completion feature was not fully ported to
    Python 3.
  - ICO/CUR: frames are now better sorted (with the same weighted
    scoring as Win32) when exporting. This was a reason why wrong sizes
    may be picked by some tools.
  - PNG: Use existing transparent PNG index first when exporting.
  - Metadata Editor: fix empty Licensor fields.
  - PS: we default to A4 for unknown images. Though arbitrary, since
    Postscript traditionally represents printed pages, it is more likely
    than other form factors.
  - DDS: support additional mimetype "image/vnd.ms-dds" (used by
    Microsoft) and "image/x-dds" (used in Linux) to detect DDS files.
  - Various plug-ins are made transient to the calling core GIMP window.
  - TIFF:
    * More Sketchbook layer mode support on load: "Inverse Alpha
      Mask" (GIMP's "Erase" blend mode) and group layers can now be set
      as "Pass-Through", defaulting to "Normal (Legacy)", depending on
      how they are set internally.
    * Sketchbook TIFF group layer loading improved.
  - ANI: When metadata fails UTF-8 validation, we fallback to loading it
    as Windows-1252 (legacy ANI files used this charset). If this fails
    too, just drop the field and continue loading.

API:

  - libgimp/PDB:
    * fix return value of deprecated gimp_drawable_levels().
  - libgimpcolor:
    * fix gimp_color_is_out_of_gamut() with grayscale space.
  - libgimpui:
    * Fix inconsistent GimpProcedureDialog buttons order on Windows.
    * Cross-process transiency is now emulated on macOS (which doesn't
      have the exact API match) for the gimp_window_set_transient*()
      functions.
    * Center plug-in windows relative to the screen on macOS.
    * GimpProcedureDialog will now use the icon set on the associated
      GimpProcedure (likely only visible on platforms showing window
      icons).
    * Resource dialogs where not appearing over the calling plug-in's
      GimpResourceChooser on macOS.
    * Cross-process transiency is now emulated on Windows too, using
      WinEvent API. Note that similarly to what is done on macOS, it
      doesn't really make the child window transient to the parent one.
      But it ensures it is made visible.
  - libgimpwidgets:
    * Plug-ins' title bar will now follow dark mode on macOS.
    * Do not show minimize button on dialogs on macOS.
    * The GimpPickButton on macOS does not pick on hovering anymore, but
      when explicitly clicked, just like on other OSes. It is more
      consistent and feels much less slow now.
  - PDB: failing PDB calls only alert through gimp_message() when run
    interactively. Non-interactive (including from last run) calls
    don't print (or pop-up) errors anymore and the caller is expected
    to check return values and process or display errors themselves if
    relevant.

Utilities:

  * gimptool can now compile and link GEGL operations with
    --cflags-geglop, --libs-geglop and --build-geglop CLI options.
  * gimptool works better on macOS and when it runs on .app bundle.
  * gimptool sets relocated PKG_CONFIG_PATH on Windows, macOS and
    AppImage relocatable bundles.

Build:

  - New analysis job running Tartan.
  - Full build CI pipeline for GIMP on macOS now on our Gitlab instance
    (hence deprecating the old CI on CircleCI, just for the sake of
    macOS).
  - .exe installer and MSIX now allows opening multiple images from "Open
    With".
  - Make sure our packages for Windows and macOS builds, as well as our
    AppImage, ship with the required libraries to create plug-ins.
  - Our minimum Windows version for our MSIX package is now 10.0.20348.0
    in order to comply with a requirement from MS about
    fileSystemWriteVirtualization. Note that the installer still works
    on Windows 10.0.0.0 and up.
  - Faster in-build GIMP runs where only the required plug-ins are
    initialized.
  - Our defcheck utility now has macOS support.
  - Some jobs are run more conditionally to avoid unecessary and
    wasteful checks:
    * file-plug-in-tests are not run on translation commits.
    * meson-health runs on specific conditions only.
  - New commit message checks in CI.
  - Our Windows installer scripts now work with any Python (without hard
    dependency on MSYS2 as it used to have when we had our 32-bit TWAIN
    code).
  - GdkPixbuf minimum requirement bumped to version 2.32.0 in order to
    drop the deprecated to-pixdata for embedded PNG resources (which
    triggered a lot of useless WARNING messages about Glycin when
    building GIMP initially).
  - clang-format file improved to better match our coding style.
  - MSVC: Python plug-ins are not installed because introspection is not
    supported there.
  - Windows installer now uses InnoSetup 7.0.2.
  - Add LLDB support to '-Ddebug-self-in-build' build option and display
    a proper discovery message when in-build GIMP crashes to encourage
    bug reporters to make stacktraces of that happening.
  - Damned Lies (translation) commits now follow our "<module>:" prefix
    rule in the commit message.

Fixed at 489beed8db. Leaving open for SA.
