CacheHelper

CacheHelper has been fully decoupled from View, and uses helper callbacks to generate caches. You should remember to place CacheHelper after other helpers that modify content in their afterRender and afterLayout callbacks. If you don't some changes will not be part of the cached content.
CacheHelper also no longer uses <cake:nocache> to indicate un-cached regions. Instead it uses special HTML/XML comments. <!--nocache--> and <!--/nocache-->. This helps CacheHelper generate valid markup and still perform the same functions as before. You can read more CacheHelper and View changes
