GIMP 2.10.30 is once again mostly a bugfix release, with many fixes and incremental improvements, not so much on the “new feature” side.

Improved file formats support¶

Several file format supports were updated with fixes or improvements: AVIF, HEIF, PSD, DDS, RGBE and PBM.

Let’s highlight in particular:

• PSD support received various types of improvements allowing it to load more sub-cases of PSD: layer masks tagged with invalid dimensions, CMYK without alpha, CMYK without layers, merged image of a 16 bit per channel RGBA which had opaque alpha channel etc. In case of CMYK PSD files, for now, GIMP will convert to sRGB to allow to view the contents of a file rather than display a message that the file is not supported.
• AVIF export now favors AOM encoder.

OS evolutions¶

Some backends got reworked to follow OS evolutions:

• Backport of selection outline drawing reimplementation from GIMP 2.99.8 for macOS Big Sur and over (already discussed patch, itself exceptionnaly backported to the 2.10.28 DMG package so that macOS users enjoyed visible selections earlier).
• On Windows, we moved from GetICMProfile() to the WcsGetDefaultColorProfile() API because the former is broken in Windows 11. Thus we were failing to get monitor profiles.
• On Linux and other OSes which might use Freedesktop portals, we implemented color picking on display (Colors dockable) with the Freedesktop API when available, keeping old implementations as fallbacks. Screenshot plug-in now also uses in priority the Freedesktop API rather than specific KDE or GNOME API (which are getting restricted for security reasons since KDE Plasma 5.20 and GNOME Shell 41).

Other improvements¶

Various improvements were made on metadata support, be it on core code as well as in the metadata plug-ins (viewer and editor).

A noteworthy fix is that the text tool won’t follow anymore the subpixel font rendering choice from system settings. Subpixel rendering is for GUI on a screen of a specific type and pixel order and is not suitable for image contents which can be zoomed in or out, showed on various screens or even printed. This change also depends on a patch we contributed to Cairo which will be available in their next release (we include the patched version in our flatpak).

Team news¶

Luca Bacci is now a core developer with git access, acknowledging his very nice contributions so far.

Lukas Oberhuber, our new macOS packager, was given “reporter” access on the main source repository which allows him to help triaging on the bugtracker: labelling, closing, reopening, and moving reports…

Translators¶

Among the 82 languages for which GIMP is available, 14 translations were updated: Brazilian Portuguese, British English, Catalan, Croatian, Finnish, Italian, Latvian, Lithuanian, Polish, Portuguese, Slovenian, Spanish, Swedish and Ukrainian.

The Windows installer now contains Portuguese localization (from Portugal, it already had Brazilian Portuguese), making it available in 35 languages. Also some previously announced translations were missing in the installer. These should be fixed now.

Translators on GIMP 2.10.30:

Anders Jonsson, Aurimas Černius, Bruce Cowan, Bruno Lopes da Silva, Daniel Mustieles, Hugo Carvalho, Jiri Grönroos, Jordi Mas, Marco Ciampa, Matej Urbančič, Milo Ivir, Piotr Drąg, Rodrigo Lledó, Rūdolfs Mazurs and Yuri Chornoivan.

GEGL¶

As usual, this release is supplemented with the release of GEGL 0.4.34 the same day as GIMP 2.10.30.

There have been some build related improvements, such as moving the implementation of ctx from the main GEGL library to one of the runtime loadable operation bundles. In operations the robustness of gegl:ripple and the gegl:magick-load powered fallback have been improved.

Contributors to the GEGL release:

Anders Jonsson, Asier Sarasua Garmendia, Boyuan Yang, dimspingos, Gavin Cui, Hugo Carvalho, Jehan, Jordi Mas, krzygorz, Lukas Oberhuber, Marco Ciampa, Matej Urbančič, Øyvind Kolås, Rodrigo Lledó, Rūdolfs Mazurs and Simon McVittie.

Downloading GIMP 2.10.30¶

As usual GIMP 2.10.30 is available on GIMP official website (gimp.org).

The Linux flatpak, Windows installer and macOS DMG package are already available and nearly all mirrors fully synced up, in less than a day from source release to binary release. This may be our new record of a perfectly timed release!

What’s next¶

While the development branch is getting most activity, we don’t forget the stable branch. This release contains several fixes which we really wanted to get out there, so we recommend everyone to update.

We are not sure we will be able to do a development release before the end of the year, so we wish you already a wonderful holiday season!

Don’t forget you can donate to the project and personally fund several GIMP developers, as a way to give back and accelerate the development of GIMP. As you know, the maintainers of GEGL and GIMP are crowdfunding to be able to work full-time on free software.
