• Fix #317230: MusicXML: credit-words text can overlay staves @lvinken ?
• Fix #317565: "I" shortcut (Instruments dialog) no longer works as expected (may be seen as by design, needed for accessibility)

• Fix #318773: Glissando on final tied note causes it to repeat, rather than sustain
• Fix #321094: Undoing a clef change when the other linked staff does not display one leads to a crash
• Fix #323561: Chord notation won't print correctly when using Edwin on a Mac and an HP printer @oktophonie ?

3.x regression (post 3.6.2 release)

• [MU4 Issue] The string "Nr." turns into "№" when using Edwin #8161 @oktophonie ?

Other urgent issues or earlier regressions with no PR yet:

• Fix #306066: Updated build for ARM (and since 2.1!)
• Fix #313298: MuseScore in Microsoft Store is outdated (and since 3.3.4!)
• Fix #313840: Issue with saving score online when using "Upload score audio" (and a custom soundfont) (still actual?)
• Fix #318866: MP3 export fails for instruments not set for Single Note Dynamics, but set for using an "expr." sound (intruduced some time after 3.2.3)

Other long-time and frequent issues (where the real cause still is very unclear):

• Very many issues and forum posts of 'no sound', where sometimes How to restore sound if playback stops working helps, but quite often not
• Fix #271185: Scores corrupted beyond repair, containing nothing but zeros

[Harmoniker1]

Isn't "improve horizontal spacing & vertical alignment" #6312?

[Jojo-Schmitz]

yes, corrected

[Harmoniker1]

Why has it been deleted?

[Jojo-Schmitz]

Fat fingered when I added #6021. It is back now

[cbjeukendrup]

• PR [MU3] Fix #317227, fix #317185: Disable centering score when opening score or switching LayoutMode #7616: Fix #317227, fix #317185: Disable centering score when opening score or switching LayoutMode already in Jojo's initial post

[Jojo-Schmitz]

Added in the initial post already ;-)

[MarcSabatella]

I have no idea what #7941 is supposed to fix, but as far as I can tell, all it does is break something that works perfectly now (scaling of line width as you change scaling for the score).

[Jojo-Schmitz]

We'll see whether it turns into something useful. So far it is just listed as a potential candidate.
Edit: it got closed now

[Tantacrul]

@Jojo-Schmitz - should this be closed now, since it is so old?

[Jojo-Schmitz]

I don't think so, there are enough things left that have not yet been ported, or at least not been checked for the neccessity.

Hmm, actually I meant #6079
The things from this issue here are mostly done on #9000 and there still isn't any further 3.x planned
