　　Changes in Pale Moon 19.0 (2013-02-20):

　　* Update of the underlying Firefox (gecko) code to v19. This has a number of consequences:

　　o Add-ons and themes may need to be updated since the UI code has changed.

　　o HTML5-implementation is more complete

　　o A number of CSS statements have their prefix removed (-moz*)

　　o Javascript now uses the IonMonkey engine by default, which is a new (faster) engine

　　o Improvements to the layout and rendering engines

　　o If you are using a language pack, you need to update it to the new version

　　* Update of the browser style. Main browser Controls and the padlock look slightly different.

　　* Several Pale Moon specific improvements to the rendering engine, noticeable in general use and certain benchmarks, to prevent browser stalls or high cpu usage on certain pages.

　　* The builds no longer use PGO (Profile Guided OpTIMization) but are globally speed-optimized.
