0.28             (2022-12-09):
Changes (list may not be complete):
* Bugfix: %GITHUB%/issues/989 "Layout#convert_pcell_to_static" does \ 
not handle"defunct" cells
* Bugfix: %GITHUB%/issues/991 Basic library not available in Python module
* Bugfix: %GITHUB%/issues/1059 Cleanup of PCell orphans after re-evaluation on load
* Bugfix: %GITHUB%/issues/1081 Using a layer properties file from recent list \ 
without layout loaded crashes KLayout
* Bugfix: %GITHUB%/issues/1138 Provide a way to suppress or redirect log output \ 
or disable warnings, specifically from file readers, in Python module
* Bugfix: %GITHUB%/issues/1178 technology-data xml results in SEGV
* Bugfix: %GITHUB%/issues/1190 General compatibility issue of \ 
Edges#extended/extended_* with deep mode
* Bugfix: %GITHUB%/issues/1216 DRC internal error on "moved"
* Bugfix: %GITHUB%/issues/1214 LEF via parser error
* Enhancement: %GITHUB%/issues/1056 X2 net names
* Enhancement: %GITHUB%/issues/1052 PDF documentation
* Enhancement: %GITHUB%/issues/1053 LEF/DEF enhancements
* Enhancement: Qt6 enabled
* Enhancement: KLayout paths
  - $KLAYOUT_HOME can now be empty string (no home folder used)
  - $KLAYOUT_PATH can now be empty string (no further and implicit search paths)
* Enhancement: Python typehints
  - Python include files are generated for Python module
* Enhancement: Properties dialog now features object list on left side (select \ 
and change)
* Enhancement: Compute area and perimeter from selection (Edit/Selection/Area \ 
and Perimeter)
* Enhancement: Callbacks for PCells
  - Allow dynamic change of some attributes (visibility, enabled etc.)
  - By implementing "callback_impl" in PCellDeclarationHelper subclasses
* Enhancement: Report browser
  - Shape user properties are turned into RDB values
  - Scanning of text objects
* Enhancement: Support for high-DPI modes (scale factor 200%)
  - "Highres" option to fully exploit resolution, normally follows \ 
screen scaling
* Enhancement: Multiple tech stacks for net tracer per technology
* Enhancement: New rulers
  - Angle
  - Radius (%GITHUB%/issues/906)
  - Multi-segment
* Enhancement: LVS
  - Generates a log view which may have useful hints
  - Schematic and extracted netlists are available as separate tabs for LVS view
* Enhancement: DRC
  - 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)
* Enhancement: "data:" URL schemes to pass direct base-64 encoded data
* Enhancement: "Close all except", "left of", "right \ 
of" etc. in layout tabs and macro editor tabs
* Enhancmennt: Drop-down list to select tab in layout views
* Enhancement: Setting for disabling "Save needed" dialog box
* Enhancement: File details are shown (dump of file header) for unknown file formats
* Enhancement: NoQt option for LayoutView
  - 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
* Enhancement: New command "-rr" (like -r but keeps application \ 
running, for UI macros)
* Enhancement: PCell errors are shown on a special error layer which is visible \ 
together with guiding shapes
* Enhancement: custom queries support micron-unit attributes (dbbox, path_dtrans \ 
etc.)
* Enhancement: custom queries highlight results of queries when selected
* Enhancement: scale and snap improvements (edge pair support, properties \ 
maintained, arrays not always flattened)
* Enhancement: auto-run macros can not be given a priority in which they are executed
* Enhancement: D25 module overhauled
  - 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
