+Breaking change "TYPO3 v9 LTS Update"
+=====================================
+
+The extension does now officially support TYPO3 CMS v9.5 LTS.
+This change contains some breaking changes:
+
+* Support for TYPO3 versions lower then 9.5 LTS has been dropped.
+
+* Due to dropped TYPO3 CMS < v9 support, also all PHP Code within ``Compatibility``
+  namespace was removed.
+
+* Fluid variable ``{request.query}`` is no longer provided, due to internal API
+  changes. Use ``{request.searchTerm}`` instead.
+
+* PHP Interface ``\Codappix\SearchCore\Connection\SearchRequestInterface`` has
+  changed, due to extending TYPO3 Interface
+  ``\TYPO3\CMS\Extbase\Persistence\QueryResultInterface``.
+
+  Therefore also PHP class ``\Codappix\SearchCore\Domain\Model\SearchRequest`` has
+  been adjusted.
