GIMP 3.0 has been more than one decade in the making as the port from GTK2 to GTK3, also transitioning away from Python 2 to Python 3 support, and a wealth of other improvements from the UI to lower down into enhancing this open-source Photoshop alternative.
The GIMP project announced on X/Twitter today that they have entered the string freeze for this much anticipated release.
If you can’t remember the name, it was probably not a good rename. “Glimpse” was the name, as the other user noted. ;-) On a more serious note, I actually liked the name Glimpse. But they did more than just renaming the project. They had plans to make it very different from Gimp too. So it probably died because of being too ambitious.
