Breaking: #91909 - sys_collection database tables moved into external extension¶
See Issue #91909
sys_collection database table and its MM table which
holds information of connected records to a “Record Collection” have
been removed from TYPO3 Core.
This feature was added as a more generic approach of the
definition along with the File Abstraction Layer in TYPO3 v6.0. The file collection
allows to create a group of files (e.g. from a folder, or from a category).
However, the more generic API was never picked up in TYPO3 Core since 2012.
The database table, the TCA definition (for editing the records in the database), and the PHP API are now available in a separate extension installable via the TYPO3 Extension Repository (https://extensions.typo3.org) or via composer (“friendsoftypo3/legacy-collections”).
The third-party extension can be used as a 1:1 drop-in replacement for the removed Core functionality.
It is not possible to modify / edit
sys_collection records anymore in the TYPO3 Backend.
The database tables are not defined anymore, so is the TCA definition.
Accessing the PHP API class will result in fatal PHP errors.
Any TYPO3 installation using the database tables
which is very unlikely.
Use the upgrade wizard or install the
to re-add the functionality - but only if it is needed.
As the PHP classes have a class alias, everything should work as before.
