[isabelle-dev] Isabelle2022-RC3 after repository fork

[Makarius]

The isabelle-dev repository is now back in post-release mode (version 
6ab4bb7cb8b2).

The release train for Isabelle2022 continues here: 
https://isabelle.sketis.net/repos/isabelle-release

If there is anything for the release, it needs to be sent to me via e-mail 
(without pushing it on the isabelle-dev repository).


Isabelle history is mostly linear, without odd forks, branches, merges of the 
proverbial "average github project". This is important to sort out problems in 
the proverbial "depths of time": I do this routinely whenever the state of 
sources is somehow unclear (and sometimes get stuck in strange merge-knots in 
the history).

So we need to be clear what is committed / pushed where: either for 
isabelle-dev or for isabelle-release (the latter will return home to 
isabelle-dev at a later stage).
