+=============
+
+The CakePHP core team is happy to announce the immediate availability of CakePHP
+5.0.9. This is a maintenance release for the 5.0 branch that fixes several
+community reported issues.
+
+Bugfixes
+--------
+
+You can expect the following changes in 5.0.9. See the `changelog
+<https://github.com/cakephp/cakephp/compare/5.0.8...5.0.9>`_ for every commit.
+
+- Fixed HTML validation for checkboxes generated by ``FormHelper``.
+- ``Table::removeBehavior()`` now cleans up the method map and finder map.
+- Improved API documentation for Inflector.
+- Removed the check for ``zend.assertions`` when debug is enabled. Cost
+  effective hosting often does not provide access to ``php.ini`` and this config
+  option cannot be changed.
