- Fixed broken link + removed redundant form descriptions (there is no point
  in repeating the title).

- Patch #7466 by TDobes: comments module would add a link of register even if "user_register" was set to 0.

- Patch #9253 by Morbus: fixed bug that manifested itself with a duplicate page when a user has submitted a comment that goes into the moderation queue. Part of the problem seemed to be that the "your comment is in the moderation queue" message was set as a theme print, as opposed to a drupal_set_message().  This patch fixes that, as well as adding a drupal_goto() to redirect the user back to where they came.

- Patch by JonBob: updated the comment module to take advantage of the latest
  menu system improvements.

* improves the doxygentation and help text.
* deletes comment_admin and comment_page; using proper callbacks instead.
* related/modified callbacks/menus/functions were tweaked to not use arg() at all.
* the "settings" subtab was weighted to -10 so it'd appear first (in prep of JonBob's local default).
* moderation pages weren't properly showing defined votes or thresholds; fixed.
* when moderation votes or thresholds didn't exist, no error stating as such was shown; fixed.
* we show "submit votes" on the moderation votes page only when votes actually exist.
* fixes the (broken in CVS) comment/reply and comment/edit features.
* fixes the (broken in CVS) "save settings" for comment view options and comment moderation.

In addition I:

* fixed a couple warnings introduced by Morbus' patch.
* fixed a couple translation bugs.
* fixed comment_node_url().

I also found that:

* the collapsed comment views (i.e. 'threaded list - collapsed) are broken.

- Patch #9010 by Morbus: reorganized the order of functions in the comment
  module.

- Marked required fields on the node (story, book, page, blog) and comment
  forms using the $required argument of the form_ functions.

- Replaced all Optional's and Required's from the taxonomy forms with proper
  use of the form_ functions.

Please check your contributed modules too!

- Patch by Steven and me: refactored the form handling of nodes. The node system is now using form_set_error() and friends like the rest of Drupal does. This makes for both a consistent user experience and consistent code. It simplifies the forms and validation code, however, it does change the node API slightly:

    * The _validate hook and the _nodeapi('validate') hook of the node API (1) no longer take an 'error' parameter and (2) should no longer return an error array. To set an error, call form_set_error().

    * The _form hook of the node module no longer takes a form hook and should not worry about displaying errors. Ditto for _nodeapi('form_post') and _nodeapi('form_pre').

- Patch #8757 by Morbus Iff: fixed redirection after comment moderation.

First tab improvements by Adrian:

  + Changed menu.inc to generate two separate lists instead of nested lists:
    that seems to be the only alternative to get rid of absolute positioning.

  + Changed the tabs code to be more sexy and put the code in misc/drupal.css
    so all themes are automagically updated.

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').

- Patch #8553 by Moshe: hide the 'add new comment' link when showing the
  comment form.

- Patch #7350 by Mathias: return part a taxonomy tree to a user-defined
  depth/level.

- Updated CHANGELOG.txt.

- Reworked comment submission.  It is less broken now.

- Improved form handling.

  + Introduced two new functions:
      1. form_set_error($name, $message): files an error against the form
         element with the specified  $name.
      2. form_has_errors(): returns true if errors has been filed against
         form elements.

  + Updated the form handling:
       1. The form_ functions will add 'class="error"' when a form field
          has been found to be erroneous.
       2. The error message is passed to theme_form_element() when the
          particular form field has been found to be erroneous.

  + I updated the user and profile module to take advantage of these new
    functions.

  + IMPORTANT: the _user() hook changed.  The 'validate' case should no
    longer retun an error message when something goes wrong but should
    set it with form_set_error().

- Patch 7444 (#35) by Pablo.  This patch addresses some issues with showing
  anonymous usernames in comments.  It does not solve all my problems, but
  others claim it works as advertised.  I'm committing this because it does
  fix some pending issues (even though that might not be the end of it).

- 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.

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

- 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.

- 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.

- Fixed problem with global session variable that caused the wrong page to
  be rendered after posting a comment.

  configurable!  Menu items can be disabled, repositioned, added and
  so on.

  Upgrading to requires you to run update.php.

  This functionality depricates some of the 'navigation modules' in the
  contributions repository.  Furthermore, modules can now 'suggest'
  menu items and site adminstrators can choose to enable them.  Modules
  in the contributions repository should try to take advantage of this.

Truncate UTF-8 patch. Introduced a new function truncate_utf8() for chopping off strings at unsure locations, without risking incomplete UTF-8 data.

  + 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.
