What's new in this version:

Features:
- Fixed: Crash on cross mode, lw > 1 and oversampling
- Fixed: Build failure against Qt6.8
Enhancement: API enhancements: several new split_... methods
on Edges, Region, EdgePairs and Texts, delivering a pair of containers with selected and unselected objects.
- Fixed: Tiling processor kept layout locks, causing DRC issues with "with_density"
- Fixed: 'Save All' was not updating the dirty flag in the inactive tabs
- Fixed: Fixing a crash when editing PCell parameters while the macro editor is open
- Fixed: Fixed a potential Crash on "save all"
- Fixed: Fixed a bug when returning a Region into a layout with cells unselected
- Fixed: Tab title were not updated on cell rename
- Fixed: Fixed a crash on certain layout queries
For example "instances of cell .*.* where inst.trans.rot == 2" was crashing

- Fixed: 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.
