Bulk mailer plugins

Plugins can now contribute email addresses to the bulk mailout facility. A typical example is a name and address list (separate from your list of site members).

Detailed timings display

Although the log display normally shows times to the nearest second, all the system logs (admin, user, rolling) in fact store times to a greater accuracy. This will depend on the server, but at least 10-20ms resolution is likely, and microsecond resolution may be available.

Rolling log

Mostly a tool for coders, this one. Its a separate log intended for events where you don't need a permanent record. So you can add debugging entries which write to the rolling log, for example - useful for those situations where echoing variables to the web page would cause problems.
