What's new in this version:

Features:
- Editor options not visible initially on layout view
- Internal error on package install
- Qt-less LayoutView creates non-editable Layout initially even if editing is requested?
- Library browser does not always display all libraries
- Python error messages should include more information
- Technology indicator is cleared after last view is closed
- Partial mode did not support Ctrl/Shift to confine movement direction
- Avoid very long error messages in DRC/LVS scripts (listing all details of the engine)
- "clone panel" did not copy custom layer stipples
- Generic "drc" sizing has to use twice the size range to catch all possible interactions
- DRC check (e.g. "sep") against second layer of "raw" type did not work in deep mode
- DRC grid check markers are now exactly aligned with vertexes they are supposed to mark
- DRC interact of polygons with texts was not working properly
- LVS: same_nets with two arguments was not working as described
- py.typed included in Python wheel now

Enhancement:
- New feature: "Screenshot to clipboard"

Introducing properties in DRC and net tagging by properties:
- This enables implementation of "connected" or "unconnected" mode checks
- This is the first release, so the feature is somewhat experimental
- For details check the documentation: look for "DRC Runsets" and browse to "DRC and user properties"
