Here what it does from the read me.

exist that are bound by the linked file.
 Improves stability when exporting complex views to AutoCAD DWG format, when the hidden lines in
those views have a large gap width.
 United Kingdom content is now included in the English installer.
 Improves stability when editing a family in the System Editor.
 Improves stability when upgrading previous release files that contain certain schedule configurations.
