•	MKI_BLOCKLIST_ROWS increased to 50, resulting in MKI_BLOCKLIST_MAX to be 500 now.

•

Pen and layer "*Standard" no longer exist in this form; they have been replaced by "- Not assigned to any Layer -" and "- Not assigned to any Pen -" respectively.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.

•

The former "Dynamic Snapping Guide" has been renamed "Temporary Objects". All corresponding constants were changed from _SNAPGUIDE to _TEMP. Other sets of elements that were previously all named "temporary" have been renamed either "provisional", "preliminary", or "precalculated" to avoid confusion among them.

•	The names of many command ID constants (MKI_MENU_*) have been changed to match their current menu placement. Some have been changed for name consistency. All constants' values remained unchanged!
