KLayout 0.28 (64-bit)

What's new in this version:

Features:
Changed:
- $KLAYOUT_HOME can now be empty string (no home folder used)
- $KLAYOUT_PATH can now be empty string (no further and implicit search paths)
- Python include files are generated for Python module
- Allow dynamic change of some attributes (visibility, enabled etc.)
- By implementing "callback_impl" in PCellDeclarationHelper subclasses
- Shape user properties are turned into RDB values
- Scanning of text objects
- "Highres" option to fully exploit resolution, normally follows screen scaling
- Angle
- Radius (#906)
- Multi-segment
- Generates a log view which may have useful hints
- Schematic and extracted netlists are available as separate tabs for LVS view
- Antenna DRC measured values output on edge pair properties and into report file
- inside, not_inside, outside and not_outside also for edge/edge and edge/polygon layers
- split_inside, split_outside for edge/edge and edge/polygon layers
- andnot (edge/edge)
- inside_outside_part (edge/polygon)
- angle-class selectors (multiples or 90 or 45 degree)
- performance enhancements
- in_and_out (edge and polygon layers)
- Enhancmennt: Drop-down list to select tab in layout views
- PixelBuffer object instead of QImage
- LayoutView can be build without Qt
- Functions exist to emulate mouse events
- Included in standalone Python module
- Allows implementation of KLayout backend in web server
- Uses a DRC subset to generate layers
- Allows booleans and specific color assignments
- Supports edges and edge pairs (will build walls)
- Not backward compatible!
- Python/Ruby API:
- DText/Text: bbox, alignment enums
- Polygon#size with vector arguments
- DBox/Box#world
- Layout#unique_cell_name
- RecursiveShapeIterator#each, RecursiveInstanceIterator#each
- Layout#clip with DBox and Cell arguments
- Better automatic conversion of enum to int and vice versa
- CellInstArray constructor with Cell argument
- AbstractMenu#insert_menu, #clear_menu
- ActionBase#icon=, #on_menu_opening, #on_triggered
- CellMapping convinience methods
- Cell#read for easy importing of a layout into a cell + subtree
- LayerMap#map and #mmap: logical layer is optional now (needed to be incremental)
- Shapes#cell and #layout
- Edges#andnot, #split_interacting, #inside, #not_inside, #outside, #not_outside and related (for Region and Edges arguments)
- GenericDeviceExtractor#define_terminal convenience methods
- Box/DBox square and rectangle convenience constructor
- Box#enlarge convenience isotropic variant
- Region#in_and_out, Edges#in_and_out

Fixed:
- "Layout#convert_pcell_to_static" does not handle"defunct" cells
- Basic library not available in Python module
- Cleanup of PCell orphans after re-evaluation on load
- Using a layer properties file from recent list without layout loaded crashes KLayout
- Provide a way to suppress or redirect log output or disable warnings, specifically from file readers, in Python module
- technology-data xml results in SEGV
- General compatibility issue of Edges#extended/extended_* with deep mode
- DRC internal error on "moved"
- LEF via parser error

Enhancement:
- #1056 X2 net names
- #1052 PDF documentation
- #1053 LEF/DEF enhancements
- Qt6 enabled
- KLayout paths
- Python typehints
- Properties dialog now features object list on left side (select and change)
- Compute area and perimeter from selection (Edit/Selection/Area and Perimeter)
- Callbacks for PCells
- Report browser
- Support for high-DPI modes (scale factor 200%)
- Multiple tech stacks for net tracer per technology
- New rulers
- LVS
- DRC
- "data:" URL schemes to pass direct base-64 encoded data
- "Close all except", "left of", "right of" etc. in layout tabs and macro editor tabs
- Setting for disabling "Save needed" dialog box
- File details are shown (dump of file header) for unknown file formats
- NoQt option for LayoutView
- New command "-rr" (like -r but keeps application running, for UI macros)
- PCell errors are shown on a special error layer which is visible together with guiding shapes
- custom queries support micron-unit attributes (dbbox, path_dtrans etc.)
- custom queries highlight results of queries when selected
- scale and snap improvements (edge pair support, properties maintained, arrays not always flattened)
- auto-run macros can not be given a priority in which they are executed
- D25 module overhauled
