　　CakePHP 2.7.0 发布，此版本 API 兼容 2.x 系列，最新的 2.6 系列版本是 2.6.9 版本，这周将会发布。
　　CakePHP 2.7.0 可以替换你现有的 2.5 或者 2.6 库，此版本包括一些新特性。
　　
　　废弃特性：

• 
  　　The>String has been renamed to CakeText. This resolves some  conflicts around HHVM compatibility as well as PHP7. The  String>
  
• 　　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>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.
