+CakePHP 5.1.0 Released
+=========================
+
+The CakePHP core team is happy to announce the immediate availability of CakePHP
+5.1.0. 5.1.0 provides a number improvements to CakePHP. 5.1.0 introduces a small
+number of deprecation warnings. Any deprecations introduced now will continue to
+have consistent behavior until their removal in 6.0.0. There is no scheduled
+date for 6.0.0 at this time.
+
+Upgrading to 5.1.0
+------------------
+
+You can use composer to upgrade to CakePHP 5.1.0::
+
+    php composer.phar require --update-with-dependencies "cakephp/cakephp:5.1.*"
+
+Deprecation Warnings
+--------------------
+
+5.1 introduces a few deprecations. All of these features will continue for the
+duration of 5.x but will be removed in 6.0. See the `migration guide
+<https://book.cakephp.org/4/en/appendices/5-1-migration-guide.html>`_.
+
+What's new in 5.1.0?
+--------------------
+
+The `migration guide
+<https://book.cakephp.org/4/en/appendices/5-1-migration-guide.html>`_ has
+a complete list of what's new in 5.1.0. We recommend you give that page a read
+when upgrading. A few highlights from 5.1.0 are:
+
+- ``RedisEngine`` now supports TLS connections.
+- ``bin/cake plugin list`` has been added to list plugin metadata.
+- Optional ``Command`` arguments can now have a ``default`` value.
+- ``BannerHelper`` was added. This command helper can format text as a banner
+  with a coloured background and padding.
+- Components can now use the DI container to have dependencies resolved and
+  provided as constructor parameters just like Controllers and Commands do.
+- The ``toString``, ``toInt``, ``toBool``, ``toDate``, and ``toDateTime``
+  functions were added. They give you a typesafe way to cast request data or
+  other input and return ``null`` when conversion fails.
+- ``pathCombine()`` was added to help build paths without worrying about
+  duplicate and trailing slashes.
+- A new ``events`` hook was added to the ``BaseApplication`` as well as the
+  ``BasePlugin`` class.
+- Support for ``point``, ``linestring``, ``polygon`` and ``geometry`` types were
+  added to the Database package.
+- ``SelectQuery::intersect()`` and ``SelectQuery::intersectAll()`` were added.
+- ``Client`` now emits ``HttpClient.beforeSend`` and ``HttpClient.afterSend``
+  events when requests are sent.
+- ``Http\Server`` now emits ``Server.terminate`` event to run logic after the
+  response has been sent in fastcgi environments. In other environments the
+  ``Server.terminate`` event runs *before* the response has been sent.
+- View cells now emit events around their actions ``Cell.beforeAction`` and
+  ``Cell.afterAction``.
+- ``Validation::enum()``, ``Validator::enum()``, ``Validation::enumOnly()``, and
+  ``Validation::enumExcept()`` were added to further simplify validating backed
+  enum values.
+- ``HtmlHelper`` can now create a meta tag with the CSRF token in it.

+upgrade from 5.0 to 5.1 a smooth one, and would appreciate any feedback you
+have on upgrade difficulties. Please open an issue and get the discussion started.
