SOLIDWORKS 2021 is fully supported with DriveWorks 18 SP2.
The CPQ DriveApp is now out of the Beta phase and fully released.
As such some minor updates have been made that requires the information held in the DriveWorks Group to be updated.
Please see Upgrading a CPQ DriveApp From Beta for more information.
When a Group has been upgraded from version 18.1 to 18.2 the version number, displayed in DriveWorks Pro Server (Groups), will display 18.1.
This is by design as the version number displayed is the database schema version of the Group.
DriveWorks 18.1 was the last version that changed the database schema.
The schema has not changed for DriveWorks 18.2
