If you are already using the previously published pre-release beta, there is no need to install the final version over it! They are the same binaries.
In detail:
- Backed out the cairo graphics engine patch by tete009 for faster drawing of html5 games (brush caching). This caused browser hangs in certain situations. The Azure patch is still present.
- Backed out the multi-threaded box blur patch by tete009 for faster drawing of, among other things, blurred shadows. This caused excessively high CPU usage on some pages/systems, and would make the browser choppy or poorly responsive.
