4.2.9 happened already, so there is no point in keeping it open :)
Straight-forward regressions:
- Bug 414576 - Zoom failure in 4.2.8 but not in 4.2.7 - https://bugs.kde.org/show_bug.cgi?id=414576 [tiar can't reproduce]
- Bug 415773 - Krita 4.2.8 freezes (lags a lot) when SHIFT-resizing brush - https://bugs.kde.org/show_bug.cgi?id=415773 [tiar can reproduce with Airbrush_Soft brush]
- Bug 414818 - Krita crashes when loading files containing colorize mask - https://bugs.kde.org/show_bug.cgi?id=414818
- Bug 414672 - Crash in uninitialized transform tool - https://bugs.kde.org/show_bug.cgi?id=414672 [might be fixed]
- Bug 415625 - Crash in transform tool [different than the previous one] - https://bugs.kde.org/show_bug.cgi?id=415625 [probably fixed by Dmitry]
- Bug 416505 - Warp and Cage Transform do not work in Jan 19th 4.3.0 pre-alpha appimage - https://bugs.kde.org/show_bug.cgi?id=416505 [Dmitry]
- Bug 415891 - Project file loads perfectly fine in seconds in 4.1.7 [and 4.2.7], never finishes loading in 4.2.8 - https://bugs.kde.org/show_bug.cgi?id=415891 [tiar, boud can't reproduce, ivan can]
- Bug 412808 - Undoing selecting new area makes the previous selection invisible in global selection mask - https://bugs.kde.org/show_bug.cgi?id=412808 (only needed cherry-picking)
- Bug 415932 - (not a regression) Some brushes doesn't follow their exact outlines as I draw with them - https://bugs.kde.org/show_bug.cgi?id=415932 [reproduce with h)_Chalk_Soft]
More problematic...:
- Bug 415086 - A file won't "draw - very important but no idea how to reproduce - https://bugs.kde.org/show_bug.cgi?id=415086 [I asked the person here to test Krita Plus which should have it fixed already]
- possibly related: bug 412808 https://bugs.kde.org/show_bug.cgi?id=412808
- Bug 415213 - Transform Tool Crashing Program After resizing - https://bugs.kde.org/show_bug.cgi?id=415213 this one can be either bug 415635 or something else, but hard to determine; needs to be checked after fixing that bug to see if it works for them or not. [I asked them to check Krita Next version after Dmitry's changes]
