The class String has been renamed to CakeText. This resolves some conflicts around HHVM compatibility as well as PHP7. The String class is still provided for compatibility reasons.
Validation::notEmpty() has been renamed to Validation::notBlank(). This aims to avoid confusion around the PHP notEmpty() function and that the validation rule accepts 0 as valid input.
SessionComponent::setFlash() has been deprecated. You should use FlashComponent instead.
SessionHelper::flash() has been deprecated. You should use FlashHelper instead.
新特性：
Plugin shells that share a name with their plugin can now be called without the plugin prefix. For example Console/cake MyPlugin.my_plugin can now be called with Console/cake my_plugin.
Configure::consume() has been added to read and delete from Configure in a single step.
CakeSession::consume() has been added to read and delete from session in a single step.
New setting level is now available in TreeBehavior. You can use it to specify field name in which the depth of tree nodes will be stored.
New method TreeBehavior::getLevel() has been added which fetches depth of a node.
SessionComponent::consume() has been added to read and delete from session in a single step.
SessionHelper::consume() has been added to read and delete from session in a single step.
Shell::param() has been added. This method allows you to read CLI options without notice errors.
The text/plain content type is no longer mapped to the 'csv' response type by RequestHandlerComponent. This helps fix issues when applications used jQuery and csv responses.
其他改进：
SQL datasources will now cast '' and null into '' when columns are not nullable and rows are being created or updated.
Argument $renew has been added to CakeSession::clear() to allow emptying the session without forcing a new id and renewing the session. It defaults to true.
CakeEmail will now use the 'default' config set when creating instances that do not specify a configuration set to use. For example $email = new CakeEmail(); will now use the 'default' config set.
ControllerTestCase::testAction() now supports an array as URL.
