+======================
+
+The CakePHP core team is happy to announce the release of CakePHP 5.4.0. With
+the release of 5.4.0, the 5.1 will no longer receive security fixes. 5.2 will
+continue to receive security fixes until the release of 5.5.
+
+What's new in 5.4.0
+-------------------
+
+Some highlights of the 5.4.0 release include:
+
+- A backwards compatible container implementation has been added to CakePHP.
+- New methods on ``Collection`` for working with keys, values, conditional
+  method chaining, and imploding to a string.
+- New ``Lock`` package for working with distributed locks.
+- Commands now have ``$this->io`` and ``$this->args`` as properties.
+- ``ConsoleHelpHeaderProviderInterface`` lets commands customize help output
+  header messages.
+- The ``#[RequestToDto]`` attribute enables automatic mapping of request data to
+  Data Transfer Objects.
+- Added ``JsonStreamResponse`` for more memory efficient streaming of large JSON
+  responses.
+- Added several new expression builders for null-safe comparisons, and aggregations.
+- Added ``Connection::afterCommit()`` to register callbacks taht run after the
+  outermost transaction commits.
+- Additional postgres index metadata reflection and generation support was
+  added.
+- ``LoggedQuery::setRedactor()`` was added to scrub sensitive data from query
+  logs.
+- Added a PSR-13 Link header implementation.
+- ``Number::toReadableSizes()`` now defaults binary units (KiB = 1024 bytes)
+  with ``setUseIecUnits()``.
+- ``I18n::setCacheConfig()`` lets you rename the ``_cake_transalations_`` cache
+  profile.
+- ``cake i18 extract`` now extracts labels added with the ``#[Label]`` attribute.
+- The ``associated`` option in ``newEntity()`` and ``patchEntity()`` supports
+  the nested array format used by ``contain()``.
+- ``TestCase::mockModel()`` enables mocking of model classes with Mockery.
+- Added new ``Utility\Fs`` classes for scanning and pattern based discovery of directory trees.
+- ``Security::encrypt()`` now supports longer keys with separate encryption and
+  authentication keys.
+- ``Text::mask()`` and ``Text::maskValue()`` were added.
+- ``FormHelper::enumOptions()`` was added to make generating form inputs from
+  enums easier.
+- The default eager loading strategy for ``HasMany`` and ``BelongsToMany``
+  associations was changed from ``select to subquery``.
+- Table methods for patching, saving, deleting and loading entities now check
+  entity class types and reject mismatched entities.
+- ``FormHelper`` now wraps hidden form blocks used for CSRF and tampering
+  prevention with ``hidden`` attributes instead of inline styles.
+- ``Application::events()`` and ``Plugin::events()`` are now called consistently
+  in both web and CLI contexts, and can use DI container services.
+
