Known Issues:
#591098: Multisite setup wont start - Multisite & single database.
#590704: I have no crawler action... - 6.14 is caching crawler requests if core cache enabled.
Notes:
Because of new menu changes, you need to press the Clear cached data button located on the "admin/settings/performance" page.
If your using the latest version of Authcache, there is a slight chance Boost will not work with it. To get around this issue, disable this setting in Boost:
admin/settings/performance/boost
Boost advanced settings
Asynchronous Opperation: output HTML, close connection, then store static file.
Run php in the background. When a cached page is generated, this will allow for faster page generation; downside is the headers are not the standard ones outputted by drupal; sends "Connection: close" instead of "Connection: Keep-Alive".
