- Patch by Steven: removed redundant permission checks.  These are no longer
  required thanks to the new 404 handling.

- Patch #5613 by Goba: fixed translation issue with archive module and removed
  some locale module code that is now part of extractor.php.

   + Tidied up the profile configuration page: grouped form elements.

   + Tidied up the block configuration settings: removed hard-coded
     table.

   + Changed the profile API to return the preferred group name, and
     changed the user module to group settings.  Modules implementing
     the _user hook will need to be udpated.

   + Removed register_form and register_validate for now.

- Patch #5567 by Goba: fixed t() functions, cleanup of locale module's help,
  fixed translation issues in taxonomy module, etc.

- Patch 5246 by Stefan: usability improvements for the locale module.

- Locale module improvements: better performance, reduce memory footprint.
  Patch by Bart.

- Updated the calls to menu() to use MENU_HIDE instead of 1

  + removes the lots of pagers and indirect pager themeing
  + add the theme_pager() function, which should be called as
    theme("pager", ...) to get a pager.

- Introduced a drupal_set_message() and drupal_get_message() function.

  Contributed themes and modules need to be updated:
   - modules: status() is no more; use drupal_set_message() instead.
   - themes: use drupal_get_message() to check for status messages and
     visualize them.

- Committed phase 4 of JonBob's menu system changes.

- Patch by JonBob:

  Phase 2 of the menu system integration project. This unifies the interface
  used by admin and non-admin pages, and deprecates the _page hook in favor of
  explicit callbacks from menu(). Breadcrumbs, titles, and help text go away
  as a result of this patch; they will return in the phase 3 patch, printed
  by the theme.

- table(...) -> theme("table", ...)

- Usability improvement: replaced many selection boxes by radio buttons.
  Patch by Stefan.

  issues).  Patch #12 by Al.

- Bugfix: charset fixes/clean-up.  Patch #52 by Al.

- Improvement: renamed some theme functions of the forum module for sake of consistency/readability.  Patch #2 by Kristjan.

- Improvement: usability improvements to the Xtemplate theme.  Patch #3 by Kristjan.

- Improvement: CSS'ified the book module pages.  Patch #3 by Al.  (I simplified the "l
ocation" part.  Al's approach gave you a bit more power but I'm not sure anyone wants
to change that.  Besides, this will change as soon we integrate the menu system so I kept it easy for now.)

- Bugfix: fixed the CREATE FUNCTION in database.mssql as it needs to be prefixed with GO for some obscure reason.  Patch by Kjartan.

- Bugfix: fixed the defaults for blocks in database.mssql so the NOT NULL fields get values.  Patch by Kjartan.

- Bugfix: changed check_form() to use htmlspecialchars() instead of drupal_specialchars() as this caused Drupal to emit incorrect form items in presence of quotes.  Example:

  <input type="submit" class="form-submit" name="op" value="Submit "top nodes" block changes" />

  IMO, drupal_specialchars() is better called xmlspecialchars() to avoid confusion.

- Bugfix: when an anonymous user visits a site, they shouldn't see any content (except the login block, if it is enabled) unless they have the "access content" permissions.  Patch by Matt Westgate.

- Improvement: improved the error checking and the error messages in the profile module.  Updated the code to match the Drupal coding conventions.  Modified patch from Matt Westgate.

- Improvement: don't generate the <base href=""> tag in the base theme; it is already emitted by theme_head().  Patch by Kristjan.

- Improvement: don't execute any SQL queries when checking the permissions of user #1.  Patch by Kjartan.

- Improvement: removed some redundant print statements from the comment module.  Modified patch from Craig Courtney.

- More charset patches by Al.

  ==> This fix requires to run update.php!

- Bugfix: made sessions work without warnings when register_globals is turned off. The solution is to use $_SESSION instead of session_register().  This fixes critical bug #1797.  Patch by Marco.
