GIMP image editor announced the third release candidate for the next major 3.0 series yesterday, with dozens of bug-fixes, requests, and translation updates.<\/p>\n

The new release fixed crash and stability issues when working on Wayland. The new GIMP running with most recent GTK 3.24.48 fixed freeze with certain actions on KDE\/Wayland, and crash when dragging layers and text glitches in certain widgets with Right-To-Left languages.<\/p>\n

The new RC3 release made a big change in how filters work. Instead of converting filter output to and from the original image’s bit-depth when stacked, it now only converts when the filter is meant to be merged in.<\/p>\n

The release also introduced new gimp-drawable-merge-filter<\/code> PDB call allows Script-fu writers to use labels to specify filter properties.<\/p>\n

There’s as well new named-argument syntax, inspired by the Racket Scheme variant. All the functions generated from plug-ins\u2019 PDB procedure must now be called with it. The benefit is that orders of arguments did not matter anymore when calling PDB procedures from the C API, as well as all introspected bindings.<\/p>\n

For Linux users, the AppImage<\/b> package that was introduced in last RC release is now official! Meaning you can now easily try out the image editor without installation. Just grab the package, add executable permission, finally run to launch the program.<\/p>\n
