Breaking: #89137 - Database fields t3ver_tstamp and t3ver_count removed

See forge#89137

Description

The two workspace related database fields t3ver_tstamp and t3ver_count have been dropped from all workspace aware database tables. Also, all code handling these fields has been removed from the code base.

Impact

The core did not show these fields to the user. It's very unlikely extensions made use of them. Admins upgrading to TYPO3 v11 can usually assume zero impact for their site functionality.

Affected Installations

All instances are affected by this change, the database analyzer will propose to drop the fields from a lot of tables including pages and tt_content.

Migration

Use the database analyzer during upgrade to drop the fields from affected database tables.
