Breaking: #98480 - TCA table "sys_template" is no longer workspace aware
See forge#98480
Description
The TCA database table sys_ is no longer workspace aware:
When changing sys_template records in a workspace in the Backend, this has
immediate effect on Live workspace.
Impact
Records of the TypoScript table "sys_template" are not available for editors, this change should not have impact on editors working on content related workspace records.
Affected installations
Instances with enabled workspaces extension may see an impact: Editing TypoScript template records immediately affects live. This is a relatively seldom scenario, an upgrade wizard is in place to set all workspace aware sys_template records to deleted, preventing them to leak to live.
Migration
Do not change sys_ rows in workspaces anymore. Any changes will
be published to live on edit.
