Breaking: #77762 - Extensions dbal and adodb moved to TER
=========================================================
See :issue:`77762`
Description
===========
The legacy extensions `dbal` and `adodb` have been removed from the TYPO3 CMS core and are only available as TER extensions.
Impact
======
Tables located on non-MySQL databases stop working until `EXT:adodb` and `EXT:dbal` have been installed from TER if a third party extensions uses the old `TYPO3_DB` API to query those tables.
Affected Installations
======================
Most installations are not affected. Instances are only affected if a loaded extension
uses the old `TYPO3_DB` database API, `dbal` and `adodb` have been loaded and if an
active table mapping to non-MySQL databases is configured.
Migration
=========
Use the upgrade wizard provided by the install tool to fetch and load the extensions from TER.
