OK, I think I got them all.

Will document Enhancements (i.e. PRs yet to be merged) from time to time (because it can take quite some time to get merged)

[KnightNine]

#83797

[goatchurchprime]

Could you add #100508 which fixes all the microphone issues I've encountered while working on the twovoip plugin? It's a design tweak that may need consideration from the core team.

[Proggle]

It looks like #87314 was added in jan 2024 then removed from the list in the next update- I can't find a PR related to it, any idea where that is?

[MJacred]

@Proggle, not sure what the thought process was. Added it back in.
The latest edit history looks like a mess, even though I only added sth…

[MJacred]

Because of various pops/cracks during playback, I added a new section called "Audio pops/cracks and the likes"

[adriano-sudario]

maybe #106608 should be included on the list too

also,

might be related to the pipeline build error on linux described on PR's description, caught when writing the tests

[MJacred]

maybe #106608 should be included on the list too

Added to list

[DeeJayLSP]

#96547 should be included in the list.
