- Patch #348448 by mfb, c960657, marvil07, cdale, jpmckinney: fixed PHP strict warnings when running tests and for PHP 5.3.

- Patch #727650 by Damien Tournoud: made OpenID more pluggable so we can extend it in contrib, and added support for Google's OpenID discovery protocol.

#606526 by axyjo and scor: Remove trailing whitespace and add newlines at end of files. Sorry, folks! But it is after code freeze. :)

#497118 by chx, catch, pwolanin, JoshuaRogers, and Jacob Singh: Remove the function registry. While the hope was that this would result in improved performance for low-end hosts, it comes at the expense of critical development experience problems and less benefit than something like APC. Class registry remains intact to facilitate autoloading.

Of all the patches to accidentally commit without a message. :( Rolling back registry rip. Let's try that again.

- Patch #331611 by sun, joshmiller, TheRec, Rob Loach, Damien Tournoud: add a poormanscron-like feature to core.
