- 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').

- Made it possible to edit blog posts and made the blog module use tabs.

- Patch #8973 by JonBob: Drupal contains many undefined variables and array indices, which makes PHP throw a lot of warnings when the reporting level is set to E_ALL. Things run fine with these warnings, but as a matter of code style if nothing else we should probably strive to avoid them. The attached fixes most of the more egregious offenders (about 95% of the warnings when I load /node on my test site).

- Patch #8747 by JonBob: extended and standardized node.module Doxygen
  comments, and made formatting and quote usage more consistent.

- Patch #7696 by TDobes: renamed 'static' to 'sticky' which is a more
  logical name.  Requires a database upgrade.

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').

- Partial patch #8284 by jseng: made the RSS auto-discovery URL absolute even though that is not strictly necessary.

added double-width dot and comma, and right-to-left question mark as sentence boundaries.

- Patch #7096 by bylund: fixed a bug with the node filters at the node administration page (administration > content)

- Patch #6612 by JonBob: extended the node API with new hooks.

- 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.

  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.

- 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.

- Patch #4902 by Goba: fix URLs in RSS feeds.
   + Make all channel links absolute.
   + Always set the $base_url as xml:base, thus providing a solid base for
     relative URLs.

- Patch 6140 by Goba: fix the 'read more'-link behavior.

- Removed broken throttle.

- Patch #6129 by Goba: fixed dependencies on search module.

- Patch 6066 by Adrian: PostgreSQL does not return 'affected rows' when doing
  a select statement.  Even though PEAR supports this functionality, it fails
  silently when using PostgreSQL.  We use the db_num_rows() function instead
  to return the amount of rows returned.  (According to Killes, the MySQL
  manual also states that it should not return affected rows on a 'select'
  statement.)

- Added a short note about the node-trim-length setting. Many people seem to expect that changing it updates existing teasers too.

- Patch 5683 by JonBob: changes the multiple type delimiter from / to -.

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

- Patch 5592 by Goba: introduced a new function, drupal_map_assoc().

  + only adds an optional parameter to url() and l(), so individual links
    can be set to be absolute
  + modifies drupal_goto() to accept the parameters of url() without the
    $absolute parameter, so cleaner invocations can be used
  + rework of some code in node_feed, making it much better to look at
    (the current code uses foreach with an immediate brake to get the first
    key of the associative array, geeeeez)
  + added xml:base to the rss tag generated by node_feed()
  + set all user mail URLs to be absolute
  + fix a small fragmented URL in user.module

- Added a welcome message written by Steven.
