Breaking: #87936 - TCA for sys_history removed

See forge#87936

Description

The TCA definition for sys_history database table was removed. It was never shown in TYPO3 Backend, and only in use for the BElog module as Extbase Domain Model. However, this relationship between logs and sys_history was decoupled in TYP3 v9.0.

The database field pid which was "0" at all times, is now removed.

Impact

Accessing $GLOBALS[TCA][sys_history] will trigger a PHP E_WARNING, and the contents of the array are not available anymore.

Affected Installations

Any TYPO3 installation with extensions accessing the global array by making use of sys_history.

Migration

If still needed, an extension should deliver the full TCA definition of sys_history.
