From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I remember years ago reading about how the GEGL backend would one day enable some "non-destructive editing" features; I just decided to figure out how that works and I see it was sort-of implemented a long time ago but in 3.0 the UI is much better: many things under the Filter menu now have a Merge filter checkbox in their dialog. When that box is unchecked, then applying the filter will make it a (non-destructive!) layer effect and an fx icon will appear for the layer (in the dockable layers dialog, which you can reach with ctrl-L if it isn't visible). You can apply any number of layer effects, and when you click the fx icon you can reorder them or modify their settings. Very cool!
Another tip (not new to 3.0): you can type
/to open the Search actions window, which lets you quickly find various functionality without needing to dig through menus to figure out where something is :)If you want to try a 3.0 release candidate before it is released, it's easy to install it from the flathub-beta repo as described here. (That page is embarrassingly out of date and says "The current development release of GIMP is 2.99.6 (2021-04-26)" but if you follow the instructions there you'll currently get version
3.0.0~rc3which is the latest release candidate from earlier this month.)That sounds really cool, thanks for letting us know!
