KLayout 0.30.6 (64-bit)

What's new in this version:

Features:
- Enhancement: #2214 Take selection modifer into account on release rather than on click
- Enhancement: #2224 Object Properties should allow layer change
- Enhancement: Point-like objects use pan-to-selection instead of zoom-to-selection when pasting
- Enhancement: More options on 'evaluate_nets' expressions, i.e. 'copy'. See documentation for details
- Enhancement: L2N format now will always include the expanded net name, so referring to a net in a log entry is possible
- Enhancement: Documentation now will also list hidden/internal classes to avoid confusing references to invisible classes
- Enhancement: DRC extend_refs function is now also available for edge and edge pair layers
- Enhancement: Pressing Ctrl key while drawing a box enforces a square, pressing Shift while drawing a box makes it centered at first location
- Enhancement: Pressing Ctrl and Shift keys does the same for box-style rulers (box, ellipse)
- Enhancement: Many operations now display edit boxes with current distances or dimensions.
- Press "Tab" to navigate to these boxes and specify distances or dimensions numerically. Press "Enter" to commit these changes and "Escape" to leave the boxes. For example: move distance, edge length during drawing of polygon or paths, box dimensions, text strings.
- Enhancement: New ruler mode "diagonal only"
- Enhancement: Multi-Rulers can now be configured to display incremental lengths
- (use "DD", "LL", "XX" and "YY" variables - see documentation)
- Enhancement: "Move By", "Scale" and "Rotate by Angle" dialogs now have an "Apply" button and values are persisted
- Enhancement: The Library view does not list cells starting with an underscore. That is a way to hide cells only used internally.

Fixed:
- LayoutView::create_measure_ruler() creates incorrect rulers
- Select fails to select from 2nd layout when two are loaded in same panel
- "save all" doesn't use the "generic options" in "save as"
- Compilation error when building with the -without-qt and -with-64bit-coord flags together
- Trace net / trace path still not working
- db::NetlistCompare: internal error when comparing schematic and netlist
- strmxor -u -l wrongly reports differences on identical layers
- klayout throws an ERROR reading a magic file with "tri ... sw"
- LoadLayoutOptions.lefdef_config.map_file fails when path contains '+' character
- Using floats for Polygon::smooth distance checks, so that precise measurements are taken
- No duplicate warning message box when drawing texts on a hidden layer
- DRC collect* functions did not work on edge pair layers
- Fixing strange snapping behavior on partial move at 45 degree directions
- selecting a recent configuration in the editor options did not select the layer if it was freshly created
- Finding of objects at the mouse location (e.g. for net probing) did not work properly for dense layouts
