Gimp 2.8.4 was released yesterday, with bug fixes
to polish the 2.8 family.
I particularly like the new fixes for this version, because it solve a strong problem introduced in the 2.8 serie ; slow and laggy selection tools and transformation widget , brush outline.
I was active on the Gimp bug report to give feedback
and thanks to the brilliant Gimp developers the problem was solved just after few days. With this version, all is much more responsive. The fix slept since this autumn waiting the release, and now released.
