- Fixed colspan in tracker table.

- Renamed '... your ...' to '... my ...' (cfr. 'my account).

- Patch #9031 by Morbus: this last tracker patch was broken - for installations where the comment.module is turned on, $comments is never set to 0, and posts that have no comments instead get the value of the last successful comment_num_all. The attached patch corrects this ($comments is set to 0 before we do anything) and also merges the if statements.

- Patch #9031 by Ber: if the comment module is not available comment_num_all()
  should not be called.

Tabs patch!

CHANGES
-------

 + Introduced tabs. First, we extended the menu system to support tabs. Next, a tab was added for every link that was (1) an administrative action other than the implicit 'view' (2) relevant to that particular page only. This is illustrated by the fact that all tabs are verbs and that clicking a page's tab leads you to a subpage of that page.

 + Flattened the administration menu. The tabs helped simplify the navigation menu as I could separate 'actions' from 'navigation'. In addition, I removed the 'administer > configuration'-menu, renamed 'blocks' to 'sidebars' which I hope is a bit more descriptive, and made a couple more changes. Earlier, we already renamed 'taxonomy' to 'categorization' and we move 'statistics' under 'logs'.

 + Grouped settings. All settings have been grouped under 'administer > settings'.

TODO
----

 + Update core themes: only Xtemplate default supports tabs and even those look ugly.  Need help.

 + Update contributed modules.  The menu() hook changed drastically.  Updating your code adhere the new menu() function should be 90% of the work.  Moreover, ensure that your modue's admin links are still valid and that URLs to node get updated to the new scheme ('node/view/x' -> 'node/x').

- Added support for 403 handling.  Patch by JonBob.  As a side benefit,
  administrators will be able to define a custom 403 page, just as they
  can define 404 pages now.

  This needs to be documented in the "Changes since / migrating to ..."
  pages.

- Tiny usability improvement for translators.  Patch by Gerhard.

  + Updated the _user() hook's "$type == 'view'" case to match the
     "$type == 'edit'" case.  That is, both have to return an associtive
     array of the format array('category' => 'fields').

   + Updated the profile pages to group fields by category.  Made possible
     thanks to the above change.

   + Moved logic out of the theme_ functions.

- Tracker and forum module improvements!

  Note: the CSS of the tracker page has changed.  Some CSS files still have
  to be updated.

- Rewrote the profile module:

   + Added a 'created' field to the users table and renamed the 'timestamp'
     fied to 'changed' (cfr. node table).  Update.php will try to determine
     a 'created' timestamp for existing users.

   + The profile module no longer uses serialized data but has its own set
     of tables.  Known existing profile data is migrated by these new tables.
       TODO: migrate the birthday field.

   + The profile fields can be grouped, and within each group, profile fields
     can be sorted using weights.

   + The profile pages can be themed.

   + The profiles can be browsed based on certain properties/settings.

   + Change the _user hook: (i) 'private_view' and 'public_view' are merged
     into 'view' as there are no private fields and (ii) 'edit_form' has
     been renamed to 'edit'.

   + Avatar handling has been refactored and is now part of the user module.
     The users table has a dedicted 'picture' field.

   + Simplified the way themes should use display/visualize pictures or
     avatars.

   + Made it possible for administrators to replace or delete avatars.

   + ...

  I hope this make for a good base to build on collectively.

- Extended tracker comments to handle project issues.

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

- Patch #5501: fixed invalid HTML in the comment and tracker module.

- Fixed tracker bug: tracker module has a line of faulty code which tries
  to get the node name in the old way.  Patch by JonBob.

- Fixed capitalization.

  + 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.

- 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.

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

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

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

- Fixed some link titles that were no longer correct due to the menu changes.

- Made sure that the link titles match the page titles.

- 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.

- Help improvements and translation improvements from Michael.  Thanks!

- Url aliasing improvements.  Patch by Matt.  See mailing list for more
  information.

- 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 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.

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

- Fixed the tracker author sort.  Patch by Moshe.

 - Tracker module: adds a missing call to tablesort_pager().
 - Tablesort:
   + add 'title' attributes
   + let arbitrary querystring params flow through to pager links
   + removed ugly border around the arrow

- Applied Moshe's tablesort patch!  Note that I changed the arrow images
  because those of Moshe where not identical.

- Updated the tracker module to the new help system scheme.

- Bugfix: changed 'INNER JOIN' back to 'LEFT JOIN'.

- Commited the URL aliasing patch.  Thanks Matt.

  This update requires you to run update.php!
