Version 5.0.13 / 4.7.52 release on 01/01/2021
- Update net browser after Edit->setNet cmd
- bugfix: save changes to SDL map list after editing.
- bugfix: schematic autorouter now routes correctly to offgrid locations.
- bugfix: Single segment rulers were not commited on 2nd click/return.
- bugfix: Clearing hilights caused possible memory corruption issue.
Version 5.0.14 / 4.7.53 release on 18/01/2021
- Properties internal cleanup. Class 'proplist' renamed 'properties'. Class pListItem has private members and accessor functions. orient_t type property removed (it was only used for DEF ROWs, and an integer prop type used in replacement).
- bugfix: stretch wire could remove extra vertices.
- Callbacks implemented for properties. dbSetPropCallback() and dbGetPropCallback() functions added. A Python callback function registered to a property will be called when that property is changed, e.g. in the query dialog of the Create Instance dialog. This allows automatic updating e.g. changing the 'fins' property on a mos device could alter the 'w' property via a callback.
To add a callback: Use the Query dialog to display properties e.g of a symbol. Enter the name of the callback function in the callback field. Only the function name is required. A python file must exist in the paython path with the same name as the callback, and extension .py (much the same as for PCells). The python function should have a single argument, 'pyDBObject', which is the dbObj which called the callback. See for example the FreePDK15 example PDK.
- Initial version of simulation environment. The current supported simulator is Xyce from Sandia Labs (https://xyce.sandia.gov/). And example PDK (XyceLib) is supplied with the Glade distribution.
- Library rebinding did not rebind some unbound instances. This has been fixed.
- Stipple patterns were incorrectly copied in certain cases from the techfile.
Version 5.0.15 / 4.7.54 release on 23/01/2021
- Internal memory manager improvements.
- enhancement: various memory leaks cleaned up. This is only likely to affect Glade API users.

- enhancement: Via contents can now be shown, like instances, when creating or moving vias if the 'Draw Moving Instance Contents' option is on (Display Options Misc dialog).
- enhancement: Runlength dependent spacing rule:
geomSpace(layer, rule, runlength, flags, msg)
Checks the spacing of projecting edges of layer is not less than rule (microns).
The length of projecting edges is specified by runlength (microns), and flags modifier for runlength can be lessthan, greaterthan, equals, not_equals, as well as horizontal, vertical, diagonal.
