What's new in this version:

Features:
Fixed:
- Copy & paste allows creating a recursive hierarchy
- A bug about layer undo
- Crash when closing application with property dialog open
- Cell.write and Layout.write are very slow on Windows if there are gigantic polygons in the cell
- Little problem with File::Setup/Application::Customize Menu
- "start" and "finish" became reserved names in PCells in version 0.29.5
- Enhancement: #1836 Allow the usage of Cell.shapes(LayerInfo(...))
- Single PCell file cannot be read
- Netlist device combination / simplify requests
- Mute diagnostic warnings on Python 3.12 debug builds, fixed a potential crash during Python module cleanup

Enhancement:
- Enhancement: Print file name before warnings and add to errors (good when reading multiple files from command line)
- Disallow empty filenames or writing to directories as this has severe side effects
- Further trying to improve stability when debugging PCells in the IDE (still not perfect)
- Enhancement: More variants of Layout#properties_id, added Layout#properties_hash and Layout#properties_array
- Enhancement: DRC - more variants for Layer#insert, such as Texts and integer-type shapes
- Properties dialog did not apply some changes when switching the object node
- Fixed a crash in the properties editor happening while selecting object type nodes in certain cases
- Enhancement: Cleaned up and enhanced documentation of LayoutToNetlist class
- Enhancement: Less agressive polygon splitting in deep mode DRC/LVS by default
- "max_area_ratio" can be a negative value now, which means that skinny diagonals are not split into a large number of triangles. This is the default.
