KLayout 0.29.0 (64-bit)

What's new in this version:

Fixed:
- Errors when adding polygons with 4 points
- DRC: some issues with edge layers
- DRC: Feeding the same layer to two-layer operations in deep mode does not render the desired result
- rdb python/ruby module: modifing items not possible as they are const
- Refactoring transformation conversion functions for complex transformation
- Instance Property form: Array Instance col/row would be more intuitive then the current row/col
- Pixel garbage in color selector button with "Auto" color selected
- DRC/LVS - connect_explicit did not accept an array of nets as single argument
- 'edge outside polygon' now consistently ignores the border of the polygon
- Warning level was ignored for some warnings in LEF/DEF reader
- Netlist reader: anonymous circuits are not checked for known parameters
- LVS - do not waste too much time analyzing failed matches

Enhanced:
- Strong default grids
- Display-->Goto Position dialog should accept + as well as - for number prefixes
- let klayout marker browser read strmxor .. xor.gds.gz, xor.oas result files
- XOR optimization for prBoundary layer
- LVS - Support for Soft Connections
- Add possibility to customize main window title
- Update Qt version for Qt bindings to 5.12.12 and 6.2.1
- New ruler type "auto measure along edge"
- Trigger ruler measurement on mouse hovering transiently
- Min and max value bounds for PCell parameters in editor The condition is not strictly enforced - for example it is not checked when changing parameters programmatically. For that, use "coerce_parameters". Still, this feature is an editing aid.
- LVS - Supporting remote must-connect connections So far, must-connect connections had to be made one level up in the hierarchy or promoted further using labels and such. Now, must-connect connections can be made at any point up in the hierarchy.
- LVS - LVS: Consider net names identical that differ in signal type suffix only - e.g. 'NET:I' is identical to 'NET'
- OASIS reader will produce layers that are listed in layer table but empty. Previously, empty layers were never created, even if listed in the layer table.
- Reading from HTTP streams and pipes now supports automatic .gz uncompression

Enhancement: New DRC Features
- "edges" method allows selecting convext/concave/step edges
- Interaction count for edge/edge edge/polygon "interacting"
- Improved handling of dots (degenerated edges) - these are now passed through the edge/edge and edge/polygon booleans and participate in "interact". This enables selecting corners and using them to select edges.

Enhancement: New RBA/pya Features
- Main window title: MainWindow#title (property)
- LayoutView#is_dirty?
- Triangulation: Region#delaunay
- Quality rasterizer: Region#rasterize
- Generic edge and polygon filters and operators support hierarchical processing with Python or Ruby callbacks: classes EdgePairFilter, EdgePairOperator, EdgePairToPolygonOperator, EdgePairToEdgeOperator, EdgeFilter, EdgeOperator, EdgeToPolygonOperator, EdgeToEdgePairOperator, PolygonFilter, PolygonOperator PolygonToEdgeOperator, PolygonToEdgePairOperator, TextFilter, TextOperator, TextToPolygonOperator Methods: EdgePairs#filter, EdgePairs#filtered, EdgePairs#process, EdgePairs#processed, same for Edges, Regions and Texts
- Polygon#split, Polygon#break, same for DPolygon, SimplePolygon, DSimplePolygon
- Keyword arguments for Python, Ruby and Expressions
- You can now also use "klayout" package inside the application (same code for Python module and application) - i.e. "import klayout.db"
- Synonyms: connect/disconnect for events for better compatibility with PyQt5
