After updating my Plasma and apps yet again I immediately checked to see if a bug that I find annoying had been fixed. It wasn’t. If you are curious it is bug 485661 from April 2024.
When I looked up the bug to see if there was any indication of progress, I noticed that there were many kmail2 bug reports that had CONFIRMED status. Some were quite old.
While I appreciate the developers going after the inevitable regressions that appear after each update but many old bugs seem to be ignored.
