===============================================
Deprecation: #81600 - Unused Extbase Exceptions
===============================================

See :issue:`81600`

Description
===========

Extbase ships with a lot of PHP Exception classes which are not used (partially anymore) due to
refactorings or backports 8 years ago - they are never thrown within TYPO3 / Extbase itself.

These PHP classes have been removed.


Impact
======

Using these exception classes will not work anymore in TYPO3 v10.


Affected Installations
======================

Any TYPO3 extbase extension using these extraordinary exceptions in their own code.


Migration
=========

PHP class aliases are in place, so all code will still work throughout TYPO3 v9, but extension authors
should migrate to other exceptions.
