KLayout 0.28.8 (64-bit)

What's new in this version:

Features:
- Enhancement: Storing (arbitrary) data in metadata
- Meta information can be attached to layout and cells
- Meta information has a string key and arbitrary value (hash, list supported)
- Optionally, meta information can be made persistent and is stored in the (KLayout specific) context section of GDS2 and OASIS
- Meta information is shown in the user properties dialog, but is not editable
- Meta information is similar, but not the same than user properties

- Enhancement: Feature request: hide empty groups
- Enhancement: feature request: create a def single/mulitpart path import option
- Enhancement: "Reload Files" popup prevents closing KLayout
- Enhancement: Add application events for indicating start/finish of restoring session
- Bugfix: Bug in RecursiveInstanceIterator
- Enhancement: Add binding for QObject::findChildren
- Bugfix: LayoutView not promoted to correct class after Plugin initialization
- Bugfix: Slow merging of polygons from width check edge pairs
- Bugfix: Region "+" skips shapes with user properties on second input
- Enhancement: Ruby debugger performance improvement - with debugger enabled, Ruby script execution was very slow
- Enhancement: Polygon "decompose_convex" tries harder to avoid generating thin slivers
- (Significant) Enhancement: Selection of labels now considers label area, not just label origin point
- Bugfix: Making 'R', 'L' and 'C' parameters for the respective Spice elements beside "value"
- Enhancement: Zoom In/Out menu functions now use the current mouse position for the zoom fixpoint (important when binding them to a key)
- Bugfix: More consistent behavior of RBA/pya: enum classes are properly made available (was for example RBA::Qt::Qt_Keys instead of RBA::Qt_Keys and pya.Qt.Keys was no fully initialized type object)
- Bugfix: Netlist reader: anonymous circuits (without definition) will not fail because of unknown parameters
- Bugfix: Closed paths lost last point after editing in partial edit mode
- Enhancement: Somewhat better grid snapping in partial edit mode
