#413908 : Cache css & js files. Allows for site to be semi-up when it would normally be in a down state. \n Improved documentation. \n Minor fixes to database opperations.

#453426 : Boost now controls cache expiration by 2 database tables: boost_cache & boost_cache_settings. This sets the stage for per content type cache expiration and crawlers to push the cache out. Performance page has been changed, you might need to re-enable boost caching on the performance page, as the variable name has been changed.

#204174 : Can now use boost & built in page caching. If boost won't cache it, then it will hand it off to core to see if that will cache it. Control this via n.

#428942 : Performance page can now generate mutiple rule sets. Still no AHAH, so you have to submit at bottom for changes to occur.

#182686 : Fixed a bug with url aliases & subdir installs; Also supressed php errors that get reported via watchdog.

#385924 : Fixed php < 5.1.0 error, added ability to not halt boost on errors, boost block shows blocking error.

#242145: Implemented a new setting for configuring whether to purge expired cache files on cron runs or not.

#323395: Allow configuring the full path to the instance-specific cache directory to alleviate HTTP_HOST/SERVER_NAME confusion.

Took over the 'Clear cached data' button on the system performance settings form, making it also clear the static page cache.
