- Updated the CHANGELOG: added a line about the book module changes, fixed
  some typos.

- Jonathan's "HTML filter" improvements.

> If turning on both filters is bad, we shouldn't allow the user to
> select both, should we? The attached patch folds the Escape HTML option
> into the same dropdown as the Filter HTML option, preventing both from
> being activated.

- Added 'escape HTML' option to the filters.  Patch by Gabor Hojtsy.

- Fixed typo.  Patch by Nick.

- Fixed bug #2874: typo in watchdog module help.  Patch by Stefan.

- 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.

- Page module simplification.  Patch by Nick Berendsen.

  > page.module:
  > -output is in theme("node") instead of theme("box"). This is a must for the
  > outline to work. The only difference is that the links are rendered by the
  > theme_node function instead of in the page_view. The links _are_ the same.

- Tidied up the usage of module_invoke() and module_invoke_all().  Patch by
  Jonathan Chaffer.

- Don't use the global theme object; use theme() instead.

- Bugfix: fixed string being check_query()-ed twice. Bug #2425.  Patch by
  Matt.

- Added page titles.  Modified version of patch 0104 by Kendow; patch updated
  for HEAD branch.

  > Modified 4.2.0 code to pass localized title text to theme header so user
  > pages have meaningful <title> element content.

- Remove node_invoke_all as it has a misleading name and is redundant with
  module_invoke_all.  Patch by Jonathan Chaffer.

- Xtemplate improvements by Kristjan:

> no changes in presentation, just a structure changes
>
> - removed inline styles from .xtmpl
> - removed duplicated #header class reference, renamed second one to #content as context$
> - simplified some CSS selectors (tested on IE and mozilla, please test on Opera, if pos$
> - some .class -> #class

Note: tested on Opera; couldn't spot any differences.

- Some breadcrumb refinements by Nick.

- Added basic breadcrumb navigation to the blog module.

- Made the forum module's breadcrumb navigation fully themable.  Patch by Nick.

- Changed 'pubdate' to 'pubDate'.  Patch by Kristjan.

  Patch by me.

- Fixed bug with taxonomy handling.  Bug #2831.  Port of patch by Jonathan
  Chaffer.

- Patch by Bart Jansen:

  <quote>

  This adds session support for anonymous users and fixes a bug/typo.

    1. changed rid for user #0 from 0 to 1 (rid 1 == anonymous user) to make
       inner join work.

    2. replaced "if ($user .." by "if ($user->uid .." because now $user is
       always set (my previous change probably caused this).

    3. db_next_id("user_uid") -> db_next_id("users_uid");
  </quote>

  I repeat:

  "This adds session support for anonymous users and fixes a bug/typo."

- Added a "alt" attribute to the logo for sake of accessibility.

- Noiseword fix.  Patch by Matt.  Reported by Bart.

  "The noise words description says that whitespace and line breaks will be
  stripped out, but the code never does any trimming.  This simple patch strips
  the whitespace from the noise words.  This probably takes care of bug #2804."

- Added support for the optional <pubdate> element in our node RSS feeds.  This
  could help reduce the number of HTTP requests and fixes some annoyances with
  RSS clients.

- Gerhard's uid 0 patches.  These patches bring various performance
  improvements.  Requires a database update.

- Commited Moshe's Xtemplate patch (slighty modified).

- Fixed the tracker author sort.  Patch by Moshe.

- Fixed bug with being able to post comments while you shouldn't.  Patch by
  Garym.

- Added an "edit account" link.

- Fixed bug #2689.  Patch by Bruno.

- Fixed bug #2690.  Patch by Bruno.

- Corrected the form description of the URL aliasing; don't add a trailing
  slash.  Reported by Stefan.

- Small bugfix for the database.mysql sql structure with the new indexes
  introduced in yesterday's forum query patch.  Patch by Matt.

- Xtemplate improvements from Ax: "i find it annoying to have two empty blocks
  (a blue - message - and a grey - footer - one) if my site doesn't have neither
  of them set."

- Tested and committed Kjartan's performance patches.  (Fixed the access check
  in update.php though.)
