Breaking: #89137 - Database fields t3ver_tstamp and t3ver_count dropped

See Issue #89137

Description

The two workspace related database fields t3ver_tstamp and t3ver_count together with their handling have been dropped from all workspace aware database tables.

Impact

The core did not show these fields to the user. It’s very unlikely extensions made use of these fields. Admins upgrading to core 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.
