Poll.module / Statistics.module: fixing bug caused by using array_merge and drupal_map_assoc. This causes array keys to be renumbered, leading to bugs.
Remember to use $array1 + $array2 instead.

- Patch by Gerhard: move the updates to database/updates.inc so packaging
  systems can by-pass update.php.

* Code cleaning: simpler structures, removed some old leftovers, ...
* Clean URLs everywhere (the old mechanism was broken anyway). Had to get rid of 'inline voting' (i.e. voting with the sideblock and ending up on the same page), but that was a bit confusing anyway.
* Simplified submission form with form_group and streamlined choice mechanism.
* Improved bar rendering in pollresults for themes with avatars, like xtemplate.

- Patch 5592 by Goba: let drupal_map_assoc() rule.  :-)

- Renamed CHANGELOG to CHANGELOG.txt for Windows uses.

- Patch 5049 by JonBob: allow a module to define multiple node types.

Patch 5287 by Stefan: multiline help texts should become inside a single $output.

- Patch 4948 by Goba: the poll module uses check_output() on the poll options.

- Re-added STYLE/ON*= filtering (this got lost a while ago due to reorganisation)
- Added form_group's to node.module's filter options
- Fixed incorrect filter usage in poll.module

  the theme functions left the poll module's poll_view() function in a
  state where it does not display the poll results or vote forms on their
  own pages, since it uses another (proprietary) $block parameter to
  handle the case when the poll is rendered to be displayed in a block.
  Patch by Goba.

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

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

- Committed phase 3 of JonBob's menu changes.  Adds an API for modules to
  define titles and breadcrumbs for their pages, and updates the theme
  system to display them.

- 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.

- Committed stage 2 of the theme system improvements!  Patch by CodeMonkeyX.

- Committed stage 1 of the menu callbacks improvements.  Patch by Jonathan.

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

- Committed part 3 of Michael's help system improvements: removed the $help
  parameter from the menu() function.

- Help system improvements: eliminated the _system hook.  Patch by Michael.

- Bloggerapi module fixes.  Patch by Kjartan.

- Coding style fixes.  Patch by Michael.

- Small poll block improvement (without configuration option).  Patch by
  Gabor.

- Help improvements and translation improvements from Michael.  Thanks!

- Associate a callback with the menu links!  (This callback is not yet being
  called but will be as soon the remaining links have been transformed to use
  the menu system.)

- Made sure the menu does not render links with no callback and no children.
  Like this, the 'create content' link is not being shown when the user has
  no permission to add any content.

- Committed Goba's translation fixes.

- Committed Al's new admin link texts.  Remarks:

  1) As explained by Al, there is still a glitch with the 'create content'
     menu.
  2) The user module part of the patch did not apply due to Kjartan's earlier
     patch.

- Committed the admin menu integration patch.  Thanks Adrian, Stefan and others.

  by Jonathan.

- Committed Nick's _content improvements.

- Fix for bug #2733: devision by zero.  Patch by Jonathan.

- Book module improvements.  This commit changes the behavior of the "view"
  hook.  See mailing list for details; search for a mail with the subject:
  '[IMPORTANT] behavior of "view" hook changed'.  Modified patch from Nick.

- Bugfix: made deleting polls work.  Patch by Marco.

- Performance improvement: changed a fair amount of "left joins" to "inner
  joins".  Patch by Gerhard.

- Committed a slightly modified version of Slavica's table prefix patch.

- Bugfix: fixed problem with changing themes.  Didn't apply Al's patch as
  the fix was somewhat simpler.  Fixes bug #2003.

- Bugfix: fixed problem with voting on certain poll pages.  Patch #37 by Al.

- Improvement: removed stupid descriptions from profile module.

- Bugfix: corrected typo in the poll module.  Patch by Al.

- Improvements: XHTML-ifications.  Patch by GmbH.

- 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: made a scalable layout form that works in IE and that behaves better with narrow themes.  Part of patch #51 by Al.

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

- Bugfix: fixed problem when register globals is turned off.  Patch 0037.poll.register_globals.patch by Al.

  (Can't we make the result URL look nicer?)
