- Patch #460320 by catch, fago, Frando: standardized, pluggable entity loading for nodes, users, taxonomies, files and comments.

#505084 by Rob Loach: Added an #attached_library() FAPI property for drupal_add_library(), for consistency with #attached_css and #attached_js.

- Patch #537434 by chx, bangpound, moshe weitzman, David Strauss: move the blog API module to contrib.

#492186 by catch, mfb, BTMash, TheRec, and rainbreaw: Fixed bug causing authoring information to never be updated (with tests).

#557932 by plach and bangpound: Fixed taxonomy term field autocomplete widgets validation, which broke after translatable fields.

- Patch #262906 by Davy Van Den Bremt, mooffie: bogus form_build_id_/nodetype/ variable created on type settings page.

#535564 follow-up by pwolanin and Gábor Hojtsy: Create 'Web services' category and move Aggregator under there.

#547846 by David_Rothstein: Fixed a missing reference operator that caused Drupal installation to fail on PHP 5.3.

#516138 follow-up by yched: Instead of a full menu rebuild, set a variable indicating it's needed. Speeds up tests by a factor of at least two.

#162788 by dww, Dave Reid, and JohnAlbin: Add option to include modules that aren't enabled in Update Status.

#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.
