+CakePHP 5.3.0 Released
+======================
+
+The CakePHP core team is happy to announce the release of CakePHP 5.3.0. With
+the release of 5.3.0, we're ending bugfix support for CakePHP 5.2. Both 5.1 and
+5.2 continue to receive security updates until the release of 5.4.0 or 6.0.0.
+It is also the end of support for bugfixes for CakePHP 4.x. The core team will
+continue to provide security updates for CakePHP throughout 2026.
+
+What's new in 5.3.0
+-------------------
+
+Some highlights of the 5.3.0 release include:
+
+- Added Redis Cluster support to ``RedisEngine``. Configure the ``cluster`` option
+  with an array of server addresses to enable cluster mode.
+- Several :ref:`cache-events` were added to allow monitoring the caching behavior.
+- ``cake plugin assets symlink`` command now supports a ``--relative`` option to
+  create relative path symlinks. This is useful when creating symlinks within
+  containers that use volume mounts.
+- ``cake server`` now supports a ``--frankenphp`` option that will start the
+  development server with `FrankenPHP <https://frankenphp.dev/>`__.
+- Added ``TreeHelper`` which outputs an array as a tree such as an array of
+  filesystem directories as array keys and files as lists under each directory.
+- Added the ability to group commands in console help output.
+- New DI container support for the ``#[Configure]`` attribute have data injected
+  from ``Configure``, and the ``TableContainer`` delegate that lets you inject
+  ORM Tables into your services.
+- Added support for additional column types in MySQL, and Postgres bringing
+  CakePHP's database type support close to parity with phinx. Queries can also
+  define optimizer hints for engine specific optimizations.
+- The new ``RateLimitMiddleware`` provides configurable rate limiting for your
+  application to protect against abuse and ensure fair usage of resources. It
+  supports multiple identification strategies (IP, user, route, API key),
+  different rate limiting algorithms (sliding window, fixed window, token bucket),
+  and advanced features like custom identifiers, request costs, and dynamic limits.
+- Added ``DateTimePeriod`` which wraps a php ``DatePeriod`` and returns ``DateTime``
+  instances when iterating.
+- Added ``SelectQuery::projectAs()`` for projecting query results into
+  lightweight Data Transfer Objects (DTOs) for read-only data access.
+- Added new fluent builders for defining the ``sortableFields`` data of your
+  pagination operations. The new builders allow you to define complex sorting
+  for both virtual and real fields, with multi-column and pinned sorting
+  support.
+- Additional assertions for redirect responses in integration tests.
+
+The `migration guide
+<https://book.cakephp.org/5/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.
