We are happy to announce the third micro-release GIMP 3.0.6. During our development of GIMP 3.2 we’ve found and fixed a number of bugs and regressions. We have backported many of those bugfixes to this stable release, so you don’t have to wait for the upcoming 3.2 release candidate to receive them!
Micro releases like 3.0.6 are focused on fixing bugs and regressions. Many of these have already been announced in our 3.1.2 and 3.1.4 news posts. However, we wanted to highlight some of the most commonly reported issues so that you are aware of the fixes.
To quote from our 3.1.4 news post:
As part of the port to GTK3, the default cursors were updated. This change led to some users experiencing the dreaded “Hand” cursor when hovering over a number slider widget. Unfortunately, the arrow cursor from GIMP 2.10 is not included on all platforms so we had to devise an alternate method. Denis Rangelov and Michal Vašut helped us find an initial solution while we continue to work on the design. We hope the current solution will make it easier for you to see where you’re clicking!
Since GIMP 3.0, we have received reports from some users that GIMP crashed for them upon opening or exporting files. We were unable to replicate the problem, until developers like Jacob Boerema and Bruno Lopes noticed a pattern - the affected users all had specific system languages like Turkish or Norwegian Bokmål. They traced the bug to our metadata library, Exiv2.
With the help of an Exiv2 maintainer Kevin Backhouse, we eventually found that the problem was caused by a bug in LLVM’s libc++, further made worse by a bug in Windows UCRT code! We have filed a report with Microsoft while Luca Bacci has contributed a patch to LLVM project, not merged yet. While waiting for the issues to be resolved at the source, Bruno has added a temporary patch to our Exiv2 build proposed by Kevin in order to workaround the issue. If you continue to have trouble with this bug, please let us know!
A number of users have reported crashes when trying to change the color of text outlines via the Text tool. This problem was discovered and fixed in our 3.1 development code, and is now fixed in 3.0.6 as well.
Certain image formats such as JPEG do not support transparency. GIMP respects those limitations when importing images, and does not automatically add transparency when opening them (unless you change this setting in Preferences). While this is important for advanced users, it can be confusing for people who are unfamiliar with image formats.
In GIMP 2.10, some special-casing was done to make certain filters and transforms work “as expected” even if the layer did not
have transparency. These were removed during the code clean-up done during GIMP 3.0’s development, and unfortunately not restored
before release. As a result, some users had reported odd results when applying Color to Alpha or rotating layers without
transparency. Since then, we have developed more generalized code to automatically add transparency to layers when necessary, which
should prevent those problems for unsuspecting users!
Due to how interconnected it was with other code changes, we back-ported a new feature from GIMP 3.1.2 - the ability to use theme colors for the brush, font, and palette dockables! You can read more about it in our original news post on the feature.
During the 2025 Libre Graphics Meeting, our co-maintainer Michael Natterer spent a good deal of time reviewing, cleaning, and updating our non-destructive (NDE) filter code. These improvements have been backported to GIMP 3.0.6 to improve the stability of our filters, and to align the development and stable codebases so we can more easily resolve any remaining issues. Jehan made further performance improvements and clarified in the interface when filters can and can not be applied non-destructively. The code to apply NDE filters to channels was also backported.
We fixed a bug related to importing Adobe Color Book (.acb) palettes CMYK and LAB palettes. We also updated our Palette Import dialogue to let you filter the view by the different palette formats that GIMP currently supports (including Adobe ASE, standard CSS, and GIMP’s own GPL format).
Again, to quote from our 3.1.4 news post:
New contributor Corentin Noël developed a fix for the Image Settings tab not appearing when printing in sandboxed applications like flatpak or snap. Due to restrictions, the tab will be created as a secondary dialogue instead - allowing you to edit those settings once again. This patch is a more future-proof version of an earlier attempt by BZZZZ creatively bypassing the sandbox portal. We appreciate the work of both contributors to fix this problem! This proposed solution is not ideal, UX-wise, compared to the original tab, but it is necessary because the portal print dialog is hardly usable without these settings.
Our two main macOS contributors Lukas Oberhuber and Gabriele Barbero have worked to fix some important issues with
our macOS build. One example of their efforts is fixing a crash when dragging a color to fill the canvas. This was caused by
our new color management code being more strictly checked by macOS compared to Linux and Windows - we have switched to a custom application/x-geglcolor mimetype to prevent this issue on all our platforms. They also improved issues with multiple
icons appearing in the macOS dock (such as when running a plug-in or script). For multi-window mode users, they also fixed a
bug where the windows would “flash” back and forth a number of times.
If you are a macOS developer and are interested in helping triage more macOS issues, we’d appreciate your support!
During development, we received reports from the Zero Day Initiative of potential security issues with some of our file import plug-ins. While these issues are very unlikely to occur with real files, developers like Jacob Boerema and Alx Sa proactively improved security for those imports.
The resolved reports are:
Jehan and Bruno backported all the build-related commits from the 3.1 development branch. For example, the nice automatic associations generation. Additionally, a bug that made it impossible for Python-based plug-ins to connect to the Internet on Windows and macOS is now fixed on the stable series.
AppImage users will also have a more reliable package from now on. The PS/EPS plug-in was restored to
work on AppImage. Also, Bruno worked to make the AppImage based on Debian 13 trixie, which
fixed many bugs at once,
such as crashing at the file dialog when there is a .json file, some PyGObject limitations,
incorrect colored subpixel rendering by Cairo and crashes when exporting JPEG 2000 images.
Similarly, the Flatpak manifest was updated to use the latest GNOME 49 runtime.
So Flatpak users, you may remove the previous org.gimp.GIMP.HEIC extension if it is
still installed, since GIMP now uses org.freedesktop.Platform.codecs-extra instead.
Jehan, lillolollo, and Jacob Boerema have worked to remove a number of warnings produced when building GIMP. While most of these were harmless, it is good to get rid of them in order to have cleaner code and build output.
There are a variety of smaller fixes in this release as well. While we can’t exhaustively cover 600+ code updates (!), here are a few more of interest.
Exif.Image.DateTime and fixing how comments are synchronized with the image when exported.Øyvind Kolås has released new updates to babl and GEGL, the underlying color management engines for GIMP.
GEGL 0.4.64 contains a number of updates and fixes. Ondřej Míchal added OpenCL to the base GeglOperationPointComposer3
class, which means more filters can now support acceleration using the GPU. He and Øyvind Kolås also worked on making the
filter testing process more robust. Jacob Boerema fixed the ZDI-CAN-27803 vulnerability for RGBE image imports. An update
was made to the gegl:mirrors filter to redraw correctly on large images (this improves GIMP’s Kaleidoscope filter).
Bruno Lopes and Jehan contributed many build process improvements and clean-up.
babl 0.1.116 brings a number of build process updates and script clean-ups by Bruno Lopes.
You can also now check the version of babl in the commandline with a --v flag thanks to Joe Da Silva.
Since GIMP 3.0.4, in the main GIMP repository:
38 people contributed changes or fixes to GIMP 3.0.6 codebase (order is determined by number of commits; some people are in several groups):
Contributions on other repositories in the GIMPverse (order is determined by number of commits):
gimp-macos-build (macOS packaging scripts) release had 10 commits by 1 contributor: Lukas Oberhuber.Let’s not forget to thank all the people who help us triaging in Gitlab, report bugs and discuss possible improvements with us. Our community is deeply thankful as well to the internet warriors who manage our various discussion channels or social network accounts such as Ville Pätsi, Liam Quin, Michael Schumacher and Sevenix!
Note: considering the number of parts in GIMP and around, and how we
get statistics through git scripting, errors may slip inside these
stats. Feel free to tell us if we missed or mis-categorized some
contributors or contributions.
Our GSoC 2025 students Gabriele Barbero and Ondřej Míchal have been added to the Core Team in our GitLab repository! This is in response to the excellent work they have done over the summer and continued to contribute afterwards.
Since the 3.0.4 news post, a new mirror have been contributed:
Mirrors are important as they help the project by sharing the load for dozens of thousands of daily downloads. Moreover by having mirrors spread across the globe, we ensure that everyone can have fast download access to GIMP.
You will find all our official builds on GIMP official website (gimp.org):
Other packages made by third-parties are obviously expected to follow (Linux or *BSD distributions’ packages, etc).
While the bulk of the work is ongoing on the main development branch (for upcoming GIMP 3.2), we felt this new stable 3.0 release was really needed, as more bug fixes accumulated. We highly recommend to update GIMP to this latest version for production work.
In the meantime, for more adventurous creators, curious people, and in particular anyone who would like to be a part in the creation of a better creative software, we also encourage you to try out our GIMP 3.1.4 development version (experimental release for the future GIMP 3.2) and report bugs or suggest User Experience improvements.
GIMP is first and foremost a Community, Free Software. What happens in it is what we all make of it. By contributing, you make it your software! 🤗
In any case, our accelerated release schedule seems to be going pretty well so far, and we are pretty happy of how GIMP 3.2 is taking shape!
Don’t forget you can donate and personally fund GIMP developers, as a way to give back and accelerate the development of GIMP. Community commitment helps the project to grow stronger!
