Breaking change
===============

Change of command name
======================

The command was renamed from "extender:rebuild" to "extender:clearClassCache"
to better reflect what the command is doing.

Change of extending configuration in 10.0.0
===========================================

Description
-----------

Since version 10.0.0 the registration happens in services.yaml

Impact
------

All class extending in ext_localconf.php needs to be replaced and converted

Migration
---------

Migrate configuration from array to yaml.

..  code-block:: php
    :caption: before ext_localconf.php

    $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['base_extension']['extender'][
        \Fixture\BaseExtension\Domain\Model\Blob::class
    ]['extending_extension'] = 'EXT:extending_extension/Classes/Domain/Model/BlobExtend.php';

..  code-block:: yaml
    :caption: after Services.yaml

    Fixture\ExtendingExtension\Domain\Model\BlobExtend:
      tags:
        -
          name: 'extender.extends'
          class: Fixture\BaseExtension\Domain\Model\Blob

Change of extending configuration in 7.0.0
==========================================

Description
-----------

Since version 7.0.0 all usage of EXTCONF is replaced with EXTENSIONS.

Impact
------

All class extending still using EXTCONF to not work anymore. So the code still
fills the array but this array is not used anymore.

Affected Installations
----------------------

All extensions that use EXTCONF in registration of class extending like.

..  code-block:: php
    :caption: before ext_localconf.php

    $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['store_finder']['extender'][
        \Evoweb\StoreFinder\Domain\Model\Location::class
    ]['sitepackage'] = 'EXT:sitepackage/Classes/Domain/Model/Location.php';

Migration
---------

Replace the usage of EXTCONF with EXTENSIONS to have the class extended again.
