Page/content prefetching and caching are used to improve the speed at which pages are rendered.  This should at least double the speed at which dynamic pages and administrator previews are generated.

Website Manager menus were redesigned, as the old versions were very slow under Windows IE.  (The menus would not appear until all images and content on the control panel was loaded; this has been corrected.)  Page reloads may be required to get the latest version of the stylesheets and menu code to make the new menus work.

We also no longer bother republishing files that have already been published.
