generally looks good. I have 2 things to add:

uploading a release to GitHub:

run this in a new empty folder as soon as all versions are available on https://download.delta.chat/desktop/:

export dcversion=v1.42.2
wget -r --no-parent -l1 --reject html https://download.delta.chat/desktop/$dcversion
rm download.delta.chat/desktop/$dcversion/*index.html*
gh release upload -R deltachat/deltachat-desktop $dcversion download.delta.chat/desktop/$dcversion/*

Release Progress issue

When making a real release make a new issue following this template to track the status of the release:

- [ ] website ()
- [ ] flathub ()
- [ ] github release ()
     - [ ] downloadable files also on github
- [ ] Mac store ()
- [ ] windows store ()
- [ ] homebrew
- [ ] aur
- [ ] nix ()
- [ ] (community) snap ()

example issue: #3582

nb: what about moving the document to /RELEASE.md - that location seems to be more common in general -
and in special it is consistent with deltachat-core - android and ios also recently changed location of their release checklist (deltachat/deltachat-android#2867, deltachat/deltachat-ios#1985)

maybe it still makes sense to mention the trick/commands to automate uploading the releases to the GitHub release. but besides that I think it's ready to merge, already much better than before, thanks for updating it 👍
