GIMP - GIMP 3.0 RC1 Released (2024)

GIMP 3.0 RC1Released

2024-11-06

by GIMP Team

We are very excited to share the first release candidate for the long-awaited GIMP 3.0! We’ve been hard at work since our last development update to get this ready, and we’re looking forward to everyone finally being able to see theresults.

GIMP - GIMP 3.0 RC1Released (1)

So, what exactly is a “release candidate” (RC)? A release candidate is something that might be ready to be GIMP 3.0, but we want the larger community to test it first and report any problems they find. If user feedback reveals only small and easy to fix bugs, we will solve those problems and issue the result as GIMP 3.0. However, we hope and expect a much larger audience to try out 3.0 RC1 - including many people who have only been using 2.10 up until now. If larger bugs and regressions are uncovered that require more substantial code changes, we may need to publish a second release candidate for furthertesting.

Wilber Icons

The current Wilber logo was created by Jakub Steiner for GIMP 2.6 in 2008! While it is still a fantastic logo, design trends have changed a bit in the last sixteen years and Wilber’s more detailed appearance sticks out on moderndesktops.

Therefore in collaboration with other contributors, Aryeom developed our new logo for GIMP3.0!

GIMP - GIMP 3.0 RC1Released (2)

If you’re interested in learning more about the design choices, usage, and design variants, please check out our logo guide. We also documented the history of the Wilber logo.

Splash Screen

Our wonderful new splash screen (shown at the top of this news post) was created by longtime contributor and artist Sevenix! You can see more of their work on their personal art page.

Going forward, we plan to change splash screens much more frequently to show off all the many kinds of art made with GIMP (photography, illustration, design…).Related to this, we have created an updated splash screen archive to highlight the work of current and previous splash screenartists.

Legacy Icon Theme Improvements

One of the major improvements from the GTK3 port is that the vector UI icons now scale more cleanly based on your preference settings. Our Legacy icon theme was mainly raster PNGs however, so it could not take advantage of the GTK3 scaling system. Contributor Denis Rangelov took on the extensive challenge of recreating the Legacy tool icons as SVGs. Now both of GIMP’s icon themes look great on HiDPIscreens!

GIMP - GIMP 3.0 RC1Released (3)

The work is not finished, as many icons are still non-scalable and some icons are still missing. Denis has expressed interest in continuing to improve the Legacy icon theme, so we hope to rename it as Classic when this project is achieved, to show it is nowwell-maintained.

One of the key changes in 2.99.18 was massive improvements to color management in GIMP. As this work was not fully finished in 2.99.18, it was a major blocker of the 3.0 RC1release.

Since that release, we have found and fixed a number of bugs and missed areas that needed to be color space aware. We have also reviewed reports by color expert Elle Stone to make sure that the color values shown by GIMP are as accurate as possible. At the same time, it’s very important to ensure that XCF project files created in GIMP 2.10 and before will render the same when opened in 3.0. For instance, one of the first Google logos was created in GIMP - and if you open the original XCF project file in GIMP 3.0 RC1, it still appears the same as it did when it was created in 1998!Therefore, we have thoroughly reviewed the various layer modes to ensure that commitment to compatibility is retained for thisrelease.

Color space invasion is a long-running project, which will continue after GIMP 3.0 isreleased.

Another task that had to be finished before the 3.0 release was finalizing the public API. Since our last news post, we finished the remaining major changes - replacing all instances of our custom GimpRGB color structures with the better color-managed GeglColor, and improving our array format so the number of elements does not have to be specified separately. This work was a long process by Jehan and Lloyd Konneker, with a great deal of bugtesting and feedback from Anders Jonsson.

In addition, a number of functions have been added, renamed, or removed from the public API compared to 2.10. For instance, an older patch by Massimo Valentini adds gimp-context-get-emulate-brush-dynamics and gimp-context-set-emulate-brush-dynamics, which allows script and plug-in developers to use the Emulate Paint Brush Dynamics setting when painting. On the other hand, the various gauss functions were all consolidated into a single function, plug-in-gauss. While this change will require some updates in existing scripts, developers now have more direct control over the Gaussian Blur effect rather than relying on hidden presetvalues.

Since the API is now stable, plug-in and script developers can begin porting their 2.10 scripts based on this release. You can find initial API documentation on our developer site. We intend to add more tutorials and porting guides here during the release candidate phase. We also encourage you to check out the Script-fu and Python plug-ins in our repository to see working examples of the new API.

Since our last update, we have continued to make improvements and bug fixes to our non-destructive filter code. Many of these issues were reported by Sam Lester during the developing and testing of his third-party GEGLfilters.

While non-destructive filters have been a very popular addition to GIMP 3.0, some early adopters have requested that we provide a way to return to the original destructive workflow. Therefore, we have added an optional “Merge Filters” checkbox at the bottom of NDE filters. If enabled, the filter will be immediately merged down after it is committed. Note that filters can not be applied destructively on layer groups – in those cases, the option to merge filters is notavailable.

GIMP - GIMP 3.0 RC1Released (4)

On a related note, Jehan also implemented storing version of filters in GIMP’s XCF project files. This will allow us to update filters in the future without impacting how older project files look when they’re opened. Additional work will be needed in GEGL to fully implement this feature, but that can be done after 3.0 without impacting existing projectfiles.

GIMP 3.0 RC1 contains several updates to the user interface. For example, more aspects of the GUI are now able to take advantage of the multi-select features implemented by Jehan in earlier versions of2.99.

We also restored the ability to use the mouse scrollwheel to flip through the different dockable dialogue tabs. This feature was built into GTK2 but removed in GTK3. Per user request, we reimplemented this feature in GIMP itself based on a similar implementation in geany.

During development, we received a report that the scrolling credits in our About Dialog could cause discomfort due to its motion. As a result we’ve added code to check your operating system’s “Reduced Animation” setting and turn off those animations in GIMP per your preferencesettings.

As we have been in a feature freeze since the last release of 2.99, most of the changes to plug-ins have been API updates and bug fixes (some of them for issues that were quite old). However, a few smaller enhancements have beenimplemented.

BMP

The BMP format now supports 64 bits per pixel images. New contributor Rupert Weber assisted us with adding support for importing this BMP format correctly. They have also submitted patches with more fixes to our BMP plug-in and testingpipeline.

TIFF

Since GIMP 2.99.16, we’ve been able to import TIFFs with Photoshop format layers. However, the Alias/Autodesk Sketchbook program created their own standard to save layers which was not compatible. Since this was marked as a bug in our issue tracker, we added support for loading layers from TIFFs saved in Sketchbook format aswell.

Both GEGL and babl have seen a number of updates since their last releases inFebruary.

GEGL 0.4.50 introduces a number of new filters created by Sam Lester.

  • InnerGlow

  • Bevel

  • GEGLStyles

These can all be accessed via the GEGL Operations tool, or by searching for them with the / search actionshortcut.

Øyvind Kolås made a number of bug fixes and improvements to the stability of GEGL. Several changes were also made related to the color space invasion in GIMP, such as adding convenience methods for getting and setting GeglColors in HSV(A) and HSL(A) color models, implemented by Alx Sa. Jacob Boerema and his GSoC student Varun Samaga B L merged a number of improvements to the OpenCL version of filters. While GIMP still does not enable OpenCL by default, their work brings us much closer to being able to so. We will discuss these improvements in a future newspost.

babl 0.1.110 also received some contributions during this cycle. Jehan implemented new conversion processes between RGB and HSL color models, which improves the performance of a number of filters compared to GIMP 2.99.18. He also fixed certain parts of the code that behaved differently depending on whether your processor supported SSE2. Øyvind Kolås improved the accuracy of several sections of code when converting from floating point to integer values. Additionally, Lukas Oberhuber found and fixed a memory leak and Jacob Boerema fixed an issue where images with NaN could cause acrash.

Let’s not forget to thank all the people who help us triaging in Gitlab, reportbugs and discuss possible improvements with us.Our community is deeply thankful as well to the internet warriors who manage ourvarious discussion channels or socialnetwork accounts such as Ville Pätsi, Liam Quin, Michael Schumacher andSevenix!

Note: considering the number of parts in GIMP and around, and how weget statistics through git scripting, errors may slip inside thesestats. Feel free to tell us if we missed or mis-categorized somecontributors orcontributions.

We are well aware that the path to GIMP 3.0 has been a long one, and GIMP 2.10 users have not had access to all of the great new features we’ve been working on over the years. Going forward, we are restructuring our development process to decrease time between releases. As briefly mentioned in our post 3.0 roadmap, we want to focus on smaller, feature-focused releases. This means that we are aiming for GIMP 3.2 to come out within a year after the final release of 3.0, rather than in 2050 as is often joked! Micro releases with bug fixes may happenin-between.

Smaller releases with few “big” features will also allow us to more thoroughly test each change, further improving the stability of each release. During the 3.0 development process, developers like Jacob Boerema, Lloyd Konneker, Bruno Lopes, and Jehan have been creating and improving our automated testing processes to further catch and identify bugs early. We will talk more about these improvements in future newsposts.

Download Mirrors

Since our last news, 8 new mirrors have been contributed to GIMPby:

  • Sahil Dhiman,India
  • FCIX, in the Dominican Republic, Australia and 2 in the USA.
  • Taiwan Digital Streaming Co.,Taiwan
  • OSSPlanet,Taiwan
  • Shrirang Kahale,India

This brings us to a total of 56 mirrors from all over theworld!

GIMP - GIMP 3.0 RC1Released (5)

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.

Platform Changes

Bruno Lopes has truly taken the lead to improve our build and packaging process on multipleplatforms.

Over the summer, he created an experimental AppImage build (as detailed in a prior news post). If you are interested in improving it further and hopefully making it available as a standard download, please get in touch! Bruno has also created flatpak build scripts to make the process of creating your own GIMP flatpak mucheasier.

A lot of work was done to improve our presence on the Microsoft Store for 3.0. Our GIMP 2.10 app was not fully integrated into the store platform due to certain limitations - it is really just a wrapper for our existing GIMP installer. Therefore it did not automatically update for users and it was not possible to automate installations with tools like Microsoft Intune. Thanks to a lot of effort on Bruno’s part, we will have a new GIMP app in the Microsoft Store which resolves these issues (and many others) for the final GIMP 3.0 release. From now, we also have a separate GIMP (Preview) which allows you to install development versions in a similar manner to the Beta flatpak on Linux. You can try it out at this Microsoft Store link.

(For technical and maintenance reasons described here, 32-bit binaries will not be available in the new MSIX packages of GIMP, which unfortunately removes support for the legacy TWAIN plug-in in x64 and arm64 packages used for quick scanning. If you depend on these, the .exe installer still supports 32-bit processors. However, the support for this architecture is planned to be dropped in the future)

Additionally, the standard Windows installer has been updated to a more modern design. It also lets you install individual language packages and lets you start up GIMP immediately after the installer is finished. For the more technically inclined, the Windows build scripts have also been ported to use PowerShell, and the cross build scripts can now runlocally.

Due to changes and updates in our software building infrastructure, we’ve had to raise the minimum OS requirement for MacOS to Big Sur (MacOS11).

GNOME Foundation fiscal host agreement

Earlier this year, the GNOME Foundation announced a fiscal sponsorship agreement with GIMP. This is all thanks to a lot of hard work by Jehan over many, many months. Our goals with this agreement are to support stable funding for developers interested in working on GIMP for a longer term through grants, and to provide easier ways for people to contribute to GIMP’s development. This is still a work-in-progress, so we will make a more detailed announcement once everything hasstabilized.

Translations

Thanks to volunteer translators, we now have a Bengali language translation of GIMP! If you are interested in translating GIMP into your own language or assisting with an existing translation, you can find out how here.

You will find all our official builds on GIMP official website (gimp.org):

  • Linux flatpaks for x86 and ARM(64-bit)
  • Universal Windows installer for x86 (32 and 64-bit) and for ARM(64-bit)
  • MSIX package (GIMP Preview) for x86 (64-bit only) and ARM(64-bit)
  • macOS DMG packages for Intelhardware
  • macOS DMG packages for Apple Siliconhardware

Other packages made by third-parties are obviously expected to follow (Linux or *BSD distributions’ packages,etc.).

We are now entering the last stage of this major release: candidates forthe final version! Though one can always hope to get a RC right the first time, experiencetells us that this RC1 — which is the result of more than 6 years ofwork — will likely have problems, bugs, probably nasty crashes. This iswhere we need you all! We rely on everyone to find andreport issues so thatthe actual 3.0.0 release can really be considered stable.🤗

Some small bugs may be considered secondary (though we still welcomereports for all bugs, even smaller ones!), because perfection barelyexists in software. There are other things in particular we really wantto catch, suchas:

  • any inconsistency or problem in the API (it will stay stable for the whole v3 series, so if there are problems to find, it’s now; we want a robust plug-inframework);
  • bugs when reading or rendering existing XCF made by former stable versions of GIMP;
  • crashes;
  • regressions;
  • proper migration of configuration from previousversions.

We are not giving out a date estimate for the actual 3.0.0 release,firstly because we can’t know for sure, secondly because each time wedo, news outlets seem to just skim every warning out of our text andtransform our words into unbreakable promises. Just know that we alsowant it to happen as soon as possible, i.e. when we can consider oursoftware to feel stableenough.

Don’t forget you can donate and personally fund GIMPdevelopers, as a way to give back andaccelerate the development of GIMP.Community commitment helps the project to grow stronger!💪🥳
