[PATCH 0/5] Docs: changes.rst: Rework

[Manuel Ebner]

There are a couple things fallacious with changes.rst. First and foremost the
name. Even though I do not really expect the name to change, it is fixed with
patch 1, because I think it is the right thing to do. Further issues are
inaccurate language (patch 2) and missing software (patch 3). Patch 4 is about
translations of the file. Final patch 5 tries to changes the way optional
software is marked.

I send this now to get some feedback before the merge window not because I'm
aiming at 7.3
