- Patch #7723 by Roderik: added strtolower()s to make PostgreSQL behave like MySQL and to be more 'forgiving' for users logging in on a PostgreSQL powered Drupal site.

- Usability improvement: simplified the administration menu of the aggregator
  module.

- Simplified the 'anonymous poster settings' of the comment module and
  made it possible to enforce a username/e-mail address.  Based on
  James Seng's work there are now 3 radio buttons:

   ( ) Anonymous users may not enter contact information
   ( ) Anonymous users may leave contact information
   ( ) Anonymous users must leave contact information

- Fixed a bug in the default theme_comment_view() function.

- Added permalinks for comments.  Requested by Michael and Christina.
  Maintainers of contributed themes might want to add permalinks too.

TODO:

- Fix the interaction design of the submission form: the page you are
  directed to and the validation of the contact information.

- Changing the comment viewing options appears to be broken?

- Made it possible for anonymous users to leave their name, e-mail address
  and the URL of their homepage.  Patch by Pablo.

- Patch #6682 by jhriggs: added form_checkboxes(), much like form_radios()
  and updated some modules to take advantage of it.

- Fixed categorize not working under sources and category views.

- Made the recent news items page, the source pages and the categorization
  pages use pagers.  Removed the 'Items per page' setting and made Drupal
  remember news items much longer.

- Code improvements by JonBob.  Thanks again.

- Added support for multiple user roles.  Patch by Jim Hriggs.

- Menu and code improvements by JonBob.

- Patch #7585 by Gerhard: extra data added by profile.module to the user
  object got saved in the user's data column even if there is a dedicated
  table for that information.

- Patch #7577 by JonBob: various code style improvements to the statistics
  module.

   + Usages of to print titles have been replaced by proper drupal_set_title()
     calls.
   + Many arg() usages dropped in favor of meaningful parameters.
   + Doxygen comments standardized and expanded.
   + Some grammatical corrections to help text.
   + Broken /statistics page linked from page navigation restored.
   + Fixed small bug in menu.inc pertaining to menu callbacks without
     arguments.

- Patch #7581 by bylund: made the archive module's calendar accessible.

See http://drupal.org/node/view/7468

- Patch #7096 by bylund: fixed a bug with the node filters at the node administration page (administration > content)

- Patch #7504 by bylund: multiple form_radio-function calls is used instead
  of a single form_radios-call. This could cause problems when trying to
  style individual form elements.

Standard text/html HTTP Content-Type was not cached, causing encoding issues on some server configurations.

- Patch #7483 by Gerhard: system_user should not return $edit.
