About this version
As usual after a new major release, a few bugs were found and fixed
(I’d prefer to have no bugs at all, of course, but I seem unable to
reach that goal).

Main news are:
* Fixed the chain tool for undo/redo operations and unallowed bond addition.
* Don’t allow new bonds between molecules in different groups.
* Prefer a cycle with cis configuration when drawing double bonds. [#24802]
* Fixed various crashes.
