CakePHP 3.2.0-RC1 Released

The CakePHP core team is happy to announce the immediate availability of CakePHP 3.2.0-RC1. This release is the first release candidate for the 3.2 branch which adds several new features to the 3.x series. We would appreciate any feedback you might have on the new features before their API definitions become stable.

Minimum PHP 5.5 Required

CakePHP 3.2 requires at least PHP 5.5.10. By adopting PHP 5.5 we can provide better Date and Time libraries and remove dependencies on password compatibility libraries.

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:

'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. 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:

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.

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.

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:

$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.

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() orDateType::useImmutable() instead.
• Cake\\ORM\\ResultSet::_calculateTypeMap() is now unused and deprecated.
• Cake\\ORM\\ResultSet::_castValues() is now unused and deprecated.

Unless there are major issues with the 3.2.0-RC1 release, we will have a stable release packaged in the next 4-5 weeks. The documentation for 3.2.0 is now available in the book and the API.

As always, a huge thanks to all the community members that helped make this release happen by reporting issues and sending pull requests.
