- Patch #29002 by Neil: list_themes() currently returns all themes, not just enabled themes. This functionality is only used in one place- configuration for disabled themes. These configuration pages can be removed with a usability improvement since you shouldn't be able to configure things which are disabled. Additionally, this allows us to remove some extra logic in system_user(). And it it more consistent with the module API which only lists enabled modules.

list_themes() sorts the results by name. This uses filesort in MySQL since there aren't any indexes. Sorting is not used except in system_user(). This one use can be handled with ksort since it is not often executed (only on the user edit screen when multiple themes are enabled).

And a one line fix to remove a variable in system_user() is in here too.

- Patch #29133 by DriesK: forum vid remains when vocabulary is deleted.  Prevents forum topics from getting lost.

  depricated by form API patch though.  Hopefully helps migration.

- Alternative solution for #28721: expand "File attachments"-group on node edit form when files are attached.

- Patch #7458 by chx: merged the XML-RPC multicall support into xmlrpc() and use lazy-loading for the XML-RPC libraries.(performance improvement).

- Patch #25522 by Cvbge: _db_query() does not return FALSE in case of errors as stated in documentation.

- Patch #28482 by Uwe: add CVS $Id$ tags to all source files in Drupal core. This allows admins to know exactly which version of which files they use. In addition I want to use CVS $Id$ tags in my upcoming security.module to check for possible vulnerabilities. That's not possible if some files simply don't have $Id$s.

Note: I also (mostly) unified the tags to use the "// ID" form instead of "/* ID */", but that's more of a cosmetic issue. I'm not sure whether *.txt files and the stuff in themes/ need tags(?).

- Patch #26637 by Robert Douglas: he documentation to theme_node clearly says the the parameter $teaser is "Whether to display the teaser only, as on the main page." Naming this parameter $main in the themes is confusing.
