+CakePHP 5.2.11

+
+The CakePHP core team is happy to announce the immediate availability of CakePHP
+5.2.11. This is a maintenance release for the 5.2 branch that fixes several
+community reported issues and regressions.
+
+Bugfixes
+--------
+
+You can expect the following changes in 5.2.11. See the `changelog
+<https://github.com/cakephp/cakephp/compare/5.2.10...5.2.11>`_ for every commit.
+
+* Fix completion command to exclude plugin-prefixed aliases. By default plugin
+  prefixed commands are not included in the ``completion`` command output. Use
+  ``-v`` to include all aliases.
+* Fixed `setTimezone()`` being called on ``Date`` instances in
+  ``RelativeTimeFormatter``.
+* Improve return type annotation for ``Validator::validate()``.
+* Improved API documentation.
+* ``E_COMPILE_ERROR`` errors are not handled as fatal errors in
