+Breaking: #67027 - Removed FLOW-compatibility from PackageManager
+=================================================================
+
+See :issue:`67027`
+
+Description
+===========
+
+The Package Manager has been simplified and trimmed down to fit the needs of the TYPO3 extensions and typical
+Composer packages. All shipped code backported from Flow was removed or refactored to be included in the TYPO3
+Core natively. Loading classes are done with the Composer class loader or by the conventions of extension namings.
+All default Composer packages can still be included as usual, however the custom Flow-logic has been removed.
+
+
+Impact
+======
+
+It is not possible to add custom Package.php loaders into TYPO3 extensions anymore to be called during runtime. It is
+not possible to configure extensions with custom `Classes/` directories and custom composer.json locations anymore.
+There is no special handling for "typo3-flow" packages anymore. The :file:`typo3conf/PackageStates.php` file now only
+contains the parts that are necessary for the TYPO3 system.
+
+
+Affected Installations
+======================
+
+All installations using custom functionality of the PackageManager not in use with the TYPO3 Core, or installations
+trying to use Flow packages natively in the TYPO3 Core.
+
+
+Migration
+=========
+
+Use Composer packages natively for class loading, or use ext_localconf.php to additionally configure a package.
