K7 Total Security

What's new in this version:

Features:
- Enhancement: DRC - more filters for edge pair collections As there are now: with(out)_area and with(out)_internal_angle

Fixed:
- Crash in netlist browser
- KLayout stalls in net browser net highlighting when net shapes contain texts
- Resistor Device extractor extracts W and L 2 times too large
- LVS: Resistor with bulk: bulk terminal swaps with A terminal
- "+" line continuation in Spice reader only effective when at beginning of line
- Technology was not assigned on new layout
- Shapes#copy_shapes does not support undo/redo
- Probe net not working for floating subcircuits in hierarchical net tracer
- Macro editor freeze after search next
- Application stalls with 'draw only border instances' mode with AREFs
- Drawing glitch

Enhancement: LVS features:
- "extract_devices" returns the device class object
- Device class object can be used to enable parameters (make them primary)
- Spice writer delegate enabled in LVS for customization of output
- "blank_circuit" specifies circuits as black boxes and skips compare
- Better propagation of symmetric nets through swappable pins
- "tolerance" and "join_symmetric_nets" can be used anywhere in the LVS script now
- "same_nets!" (with exclamation mark) for strong matching of nets
- "same_nets" accepts glob pattern now

Enhancements: RBA/pya:
- Device#net_for_terminal with terminal name
- Circuit#nets_by_name with glob pattern
- Netlist#is_case_sensitive?, Netlist#case_sensitive=
- Netlist#nets_by_name to get nets from pattern
- CellView#context_trans and CellView#context_dtrans

- Enhancement: Ruby 3.0 basic enabling
- Enhancement: DRC "extent" accepts a cell name pattern now to deliver cell bounding boxes
- Bugfix: reverted change of #796 DXF version is back to AC1006 which seems to be more compatible with most consumers of DXF files. Using 1016 AC1014 seems to require much more meta information I cannot provide without deeper insight into the DXF structure.
