Yes, another release is imminent. The LEF/DEF parsers have been enhanced to support NONDEFAULTRULES in LEF/DEF, also there are 2 bugs recently found:
– a recent change meant vias were sometimes not being displayed in LEF/DEF data
– some nets were not being shown in DEF routing.
These are related to support for LEF/DEF 5.7 version and will be in 4.1.54 hopefully in the next few days.
If you find any more LEF/DEF bugs please let me know!
