0.27.3          (2021-07-23):
* Enhancement: DRC - more filters for edge pair collections
        As there are now: with(out)_area and with(out)_internal_angle
* Bugfix: %GITHUB%/issues/846 Crash in netlist browser

* Bugfix:  %github%/issues/851  KLayout  stalls  in  net  browser  net
  highlighting when net shapes contain texts

* Bugfix: %GITHUB%/issues/854 Resistor Device extractor extracts W and
  L 2 times too large

* Bugfix: %GITHUB%/issues/856 LVS: Resistor with bulk: bulk terminal
  swaps with A terminal

* Bugfix: %GITHUB%/issues/858 "+" line continuation in Spice reader

  border instances' mode with AREFs

* Bugfix: %GITHUB%/issues/875 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.
