+CakePHP 5.2.9
+==============
+
+The CakePHP core team is happy to announce the immediate availability of CakePHP
+5.2.9. 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 5.2.9. See the `changelog
+<https://github.com/cakephp/cakephp/compare/5.2.7...5.2.9>`_ for every commit.
+
+* Improve PHPUnit usage in tests.
+* Fixed DI integration for Components.
+* ``TableLocator`` can now fetch table instances by full class name.
+* Fixed default value reflection and for SQLite boolean columns.
+* Fixed how ``Socket`` detects connection interruptions, by deprecating
+  ``$connected`` property, and using ``is_resource()`` instead. This should
+  improve behavior of ``SmtpTransport`` in long running processes.
+* Improved typehints for ``SelectQuery``.
