The latest GIMP release (version 2.10.36) introduces a fun new gradient tool and support for additional palette formats. More notably, this might be "the next to last release in the 2.10 branch," meaning that the delayed GIMP 3.0 launch should occur relatively soon. Even if you're uninterested in today's update, the GIMP Team suggests installing it for security fixes.
