•

Pen and layer "*Standard" no longer exist in this form; they have been replaced by "- Not assigned to any Layer -" and "- Not assigned to any Pen -" respectively. Functionally, this makes no difference. The former line pattern "*Standard" has been renamed "- Solid Line -". All other "*Standard" have been renamed to "- Standard -" to be more recognizable.
