+CakePHP 5.3.0-RC2 Released
+============================
+
+The CakePHP core team is happy to announce the second release candidate for
+CakePHP 5.3.0. Since the previous release candidate, the following changes have
+been made:
+
+- Added ``ExistsInNullable`` rule class to make it easier to create exists in
+  rules that allow nulls.
+- Bugfixes and Improvements to the rate limiter middleware.
+- Improved API documentation.
+- ``SortField`` treats 'desc' as reverse of the default direction now.
+- Fixed ``maxLimit`` restriction on ``PaginatorHelper::limitControl()``.
+- Fixed missing type mappings in database schema.
+- Missing abstract types no longer raise exceptions. Instead a String type is
+  returned.
+- Loading plugin classes with the class name of ``Plugin`` is now deprecated.
+- Added additional data to cache engine events.
+- Fixed deserialization error in ``TableSchema``.
+- Added verbose mode output for the ``version`` command.
+- Improved error messages when a command is missing.
+- Added ``Http\RedirectTrait`` to make it easier to build redirect responses in
+  applications and plugins.
+- ``Association::__isset()`` now only checks for associations, to be aligned
+  with ``__get()``.
+- Commands can now implement the ``CommandHiddenInterface`` marker interface to
+  hide a command from command listings.
+
+What's new in 5.3.0
+-------------------
+
+The `migration guide
+<https://book.cakephp.org/5.next/en/appendices/5-3-migration-guide.html>`_ has
+a complete list of what's new in 5.3.0. We recommend you give that page a read
+when upgrading as it notes the behavior changes present in 5.3.0.
+
+How you Can Help
+----------------
+
+You can help deliver 5.3.0 by contributing in one of many ways:
+
+#. Check the `documentation <https://book.cakephp.org/5.next/en/>`_ for mistakes,
+   outdated, unclear or broken examples. We've been trying to update the
+   documentation as we go, but there are likely examples or sections we've
+   missed.
+#. Try it out! Give CakePHP 5.3.0 a test drive. Let us know how upgrading
+   went and if there were any rough spots.
+#. File issues for regressions in existing features, or suggest new features.
+   Even if those features don't make it into 5.3.0, we're early in the process
+   of planning 5.3 and value community feedback.
