I just realised that the error mentioned at issue 5251 
(https://sourceforge.net/p/testlilyissues/issues/5251/#f53c) is a 
regression:

2.18.2 good
2.19.27 good
2.19.28 bad
2.19.83 bad
master good (and added regtest multi-measure-rest-number-threshold.ly)

Probably one of the four commits for issue 4594 (2e22eccf and ancestors) 
introduced the bug.

So I’d vote for cherry-picking 253b2489, 349fb569, c7bf27ad even though 
they haven’t been on your list.

> 3ba581df6a Issue 5490: fix for wrong clefs.varC_change
The varC clefs are a 2.19 feature. I think that new features in stable 
versions should be bug-free if possible so I’d vote for cherry-picking 
this too.

The wrong prall glyphs have annoyed me for years now and have seen them 
every now and then in scores on the internet. It’s a simple fix, I don’t 
expect heavy side effects (at least for 5489/1) so I’d vote for picking 
this.

New features, don’t pick.

Simple fix, backwards-compatible, pick.

Syntax change, don’t pick. Off-topic: maybe 2.22 or 2.24 can have MMRs 
and rests be the same in the input language?

> 1272e45b49 Issue 5526 Add ly version to swing.ly
swing.ly is not part of stable/2.20 branch. IMHO swing.ly is broken and 
should be postponed to 2.22, see 
https://lists.gnu.org/archive/html/bug-lilypond/2019-11/msg00023.html

\ambitusAfter is not part of stable/2.20 so don’t pick.

> 17d3d3a151 Issue 4362/1: head completion uses dotted breves
> 49f41bf1c6 Issue 4362/2: add regtest
Simple fix, I’d consider picking it.

> 3300acdd8d Issue 5532/1: \ottava doesn’t confuse ambitus
> 04a0052411 Issue 5532/2: add regtest
Simple fix, I’d consider picking this.

However this one improves 5532/2 and might be picked.

We don’t want crashes in stable versions, do we? ;)
