The CakePHP core team is happy to announce the immediate availability of
CakePHP 3.2.0. This is the first stable release for the 3.2 branch. Going
forward 3.1 will only receive security updates. 3.2 is a backwards
compatible release with 3.1 and 3.0 and provides new features and
performance improvements.
Minimum PHP 5.5 Required
------------------------
CakePHP 3.2 requires at least PHP 5.5.9. By adopting PHP 5.5 we can provide
better Date and Time libraries and remove dependencies on password
compatibility libraries.
Deprecations
------------
As we continue to improve CakePHP, certain features are deprecated as they
are replaced with better solutions. Deprecated features will not be removed
until 4.0:
* ``Shell::error()`` is deprecated because its name does not clearly
indicate that it both outputs a message and stops execution. Use
``Shell::abort()`` instead.
* ``Cake\Database\Expression\QueryExpression::type()`` is deprecated. Use
``tieWith()`` instead.
* ``Cake\Database\Type\DateTimeType::$dateTimeClass`` is deprecated. Use
DateTimeType::useMutable() or DateTimeType::useImmutable() instead.
* ``Cake\Database\Type\\DateType::$dateTimeClass`` is deprecated. Use
``DateTimeType::useMutable()`` or ``DateType::useImmutable()`` instead.
* ``Cake\ORM\ResultSet::_calculateTypeMap()`` is now unused and deprecated.
* ``Cake\ORM\ResultSet::_castValues()`` is now unused and deprecated.
Disabling Deprecation Warnings
------------------------------
Upon upgrading you may encounter several deprecation warnings. These
warnings are emitted by methods, options and functionality that will be
removed in CakePHP 4.x, but will continue to exist throughout the lifetime
of 3.x. While we recommend addressing deprecation issues as they are
encountered, that is not always possible. If you'd like to defer fixing
deprecation notices, you can disable them in your **config/app.php**:
```php
'Error' => [
'errorLevel' => E_ALL & ~E_DEPRECATED & ~E_USER_DEPRECATED,
]
```
The above error level will suppress deprecation warnings from CakePHP.
Carbon Replaced with Chronos
----------------------------
The Carbon library has been replaced with [cakephp/chronos]
(https://github.com/cakephp/chronos). This new library is a fork of Carbon
with no additional dependencies. It also offer a calendar date object, and
immutable versions of both date and datetime objects.
New Date Object
---------------
The ``Date`` class allows you to cleanly map ``DATE`` columns into PHP
objects. Date instances will always fix their time to ``00:00:00 UTC``. By
default the ORM creates instances of ``Date`` when mapping ``DATE`` columns
now.
New Immutable Date and Time Objects
-----------------------------------
The ``FrozenTime``, and ``FrozenDate`` classes were added. These classes
offer the same API as the ``Time`` object has. The frozen classes provide
immutable variants of ``Time`` and ``Date``. By using immutable objects,
you can prevent accidental mutations. Instead of in-place modifications,
modifier methods return *new* instances:
```php
use Cake\I18n\FrozenTime;
$time = new FrozenTime('2016-01-01 12:23:32');
$newTime = $time->modify('+1 day');
```
In the above code ``$time`` and ``$newTime`` are different objects. The
``$time`` object retains its original value, while ``$newTime`` has the
modified value. As of 3.2, the ORM can map date/datetime columns into
immutable objects as well.
CorsBuilder Added
-----------------
In order to make setting headers related to Cross Origin Requests (CORS)
easier, a new ``CorsBuilder`` has been added. This class lets you define
CORS related headers with a fluent interface.
RedirectRoute raises an exception on redirect
---------------------------------------------
``Router::redirect()`` now raises
``Cake\Network\Routing\RedirectException`` when a redirect condition is
reached. This exception is caught by the routing filter and converted into
a response. This replaces calls to ``response->send()`` and allows
dispatcher filters to interact with redirect responses.
ORM Improvements
----------------
* Containing the same association multiple times now works as expected, and
the query builder functions are now stacked.
* Function expressions now correctly cast their results. This means that
expressions like ``$query->func()->current_date()`` will return datetime
instances.
* Field data that fails validation can now be accessed in entities via the
``invalid()`` method.
* Entity accessor method lookups are now cached and perform better.
Improved Validator API
----------------------
The Validator object has a number of new methods that make building
validators less verbose. For example adding validation rules to a username
field can now look like:
```php
$validator->email('username')
->ascii('username')
->lengthBetween('username', [4, 8]);
```
Console Improvements
--------------------
* ``Shell::info()``, ``Shell::warn()`` and ``Shell::success()`` were
added. These helper methods make using commonly used styling simpler.
* ``Cake\Console\Exception\StopException`` was added.
* ``Shell::abort()`` was added to replace ``error()``.
StopException Added
-------------------
``Shell::_stop()`` and ``Shell::error()`` no longer call ``exit()``.
Instead they raise ``Cake\Console\Exception\StopException``. If your
shells/tasks are catching ``\Exception`` where these methods would have
been called, those catch blocks will need to be updated so they don't catch
the ``StopException``. By not calling ``exit()`` testing shells should be
easier and require fewer mocks.
Helpers initialize()
--------------------
Helpers can now implement an ``initialize(array $config)`` hook method like
other class types.
FormHelper
----------
The ``action`` key for ``FormHelper::create()`` has been deprecated. You
should use the ``url`` key directly.
Fatal Error Memory Limit Handling
----------------------------------------------------
A new configuration option ``Error.extraFatalErrorMemory`` can be set to
the number of megabytes to increase the memory limit by when a fatal error
is encountered. This allows breathing room to complete logging or error
handling.
Development on 3.3 will now start. The
[Roadmap](https://github.com/cakephp/cakephp/wiki/3.3-Roadmap) for 3.3 is
still incomplete, so if there is a feature or improvement you'd like to see
reach out on IRC and github. The documentation for 3.2.0 is currently
available in the [book](http://book.cakephp.org/3.0/en) and the
[API](http://api.cakephp.org/3.2).
As always, a huge thanks to all the community members that helped make this
release happen by reporting issues and sending pull requests.
