- Patch #913528 by chx, Berdir, catch, tstoeckler, yched, dereine: create new boolean field 'Cannot create references to/from string offsets nor overloaded objects'.

- Patch #902264 by Damien Tournoud: move hook_field_schema() to .install files so we can get the upgrade path to work.

- Patch #780154 by chx, noahb, dhthwy, pwolanin, aspilicious, jhodgdon, dereine, bjaspan: listing API for field API.

#331951 by aspilicious, sun, jhodgdon, Morbus, et al: Figure out and apply coding standard for casting.

- Patch #652834 by yched, effulgentsia: changed Field formatters as render arrays to increase performance (and to clean-up the code).

- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.

- Patch #606934 by matt2000, johanneshahn, yched: fixed bug with boolean fields, and added more field type tests.

- Patch #605930 by bjaspan: fixed problem with list field static caching in field_update_field(). Added some first list tests too!

- Patch #572618 by effulgentsia, pwolanin, sun: all theme functions should take a single argument. Code clean-up and performance improvement. Woot.

#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.

#369964 by yched and bjaspan: Refactor field validation and error reporting. Field API no longer coupled to Form API. Hooray.
