* Bug: %GITHUB%/issues/1976 Crash on cross mode, lw > 1 and oversampling
* Bug: %GITHUB%/issues/1987 Build failure against Qt6.8
* Enhancement: %GITHUB%/issues/1989 API enhancements: several new split_... methods
  on Edges, Region, EdgePairs and Texts, delivering a pair of containers with
  selected and unselected objects.
* Bug: %GITHUB%/issues/1993 Tiling processor kept layout locks, causing DRC \ 
issues with "with_density"
* Bug: %GITHUB%/issues/1997 Can not find a file in Open Recent menu (a string \ 
unescaping bug)

* Bugfix: Fixing a crash when editing PCell parameters while the macro editor is open
* Bugfix: Fixed a potential Crash on "save all"
* Bugfix: Fixed a bug when returning a Region into a layout with cells unselected
* Bugfix: Tab title were not updated on cell rename
* Bugfix: Fixed a crash on certain layout queries
  - For example "instances of cell .*.* where inst.trans.rot == 2" was \ 
crashing
* Bugfix: Fixing two problems with layer mapping
  - Mapping "[*/*] 100/0:0/0" (for example) created 0/0 two times when \ 
the input contains 100/0 and 0/0. Now
    it is a single layer only
  - The mapping table generated from strings now uses layer indexes from a range \ 
that should not collide
    with existing layer indexes.
