- Patch #19451 by JonBob: improved consistency of module descriptions.  We should write guidelines for this -- maybe in the PHPDoc code of the _help hook.

- Patch #16246 by Moshe: "Here is a patch for node.module since thta hunk failed last time. Note that I've removed the 'delete' link since it doesn't work and is mostly obsolete with the 'mass delete' feature.  I've also added smart destination andling to the 'url alias delete' feature."

- Patch #16246 by Moshe: added mechanism to direct the user back to the referring page after completing a form.
  (Moshe: the patch against node.module failed to apply.)

   * Less logic in theme code.
   * Encourages use of the menu system.
   * Easier to find where a title or breadcrumb comes from in other people's code because there are less places to look. Look in menu and then grep for the appropriate set function. Looking for calls to theme_page() is hard because there are too many of them.
   * Very slightly more efficient.

- Patch #12783 by Stefan: various small consistency/usability improvements.

- Patch #11952 by Neil Drumm: the path module's help text contained information that was no longer up-to-date.

- Patch #10603 by TDobes: bugfix: URL aliases got lost when deleting revision.

- Patch #8179 by JonBob: reintroduced menu caching.

- Patch by JonBob: for consistency and readability, add brief descriptions of each source file inside the @file comment block at the head of the file. This helps with Doxygen indexing, and also allows neophytes to see what a file does immediately on opening the source, regardless of the organization of the hooks.

- Code improvements by Stefan: use capital letters for header titles (and added some missing t() functions).

- Code improvements by Stefan: made all status messages consistent (and easier to translate).

- Patch #9983 by Stefan: usability improvement: made sure all status messages start with a capital letter.

- Patch #6760 by JonBob: refactored the taxonomy module URLs to be nicer, improved the code/Doxygen comments.

  As discussed before, the path "taxonomy/page/or/1,2" becomes "taxonomy/term/1+2" and the path "taxonomy/page/and/1,2" becomes "taxonomy/term/1,2". The most common case of listing nodes attached to a single term becomes simpler, since it doesn't require a meaningless "or" or "and". A depth of "0" is assumed, but a positive integer or "all" can be used. Feeds are available at "taxonomy/term/1+2/all/feed" and the like.

  This iteration of the patch also changes the structure of taxonomy_select_nodes(), since it was not following Drupal conventions. A handful of contrib modules call this function, and will need to be updated. Instead of passing in a $taxonomy object containing parameters for the function, the parameters are passed independently. This simplifies the code quite a bit. The queries were changed to only return node IDs for speed; all results from this function are passed through node_load() anyway, so the extra information returned was discarded. The AND query was also changed to avoid the strange trick and remove an extra query, at the expense of a table join per root term in the AND. This cleans up the code substantially while at the same time enabling the use of AND with a depth parameter.

  TODO: update contribution modules.

- Small usability improvement thanks to using drupal_goto() after deleting an
  alias.

- Patch by Matt: made it possible to alias an URL multiple times.

- More tab-improvements by JonBob: improved support for the default tabs!

- Simplified some of the help texts.

- Removed left-over instance of theme('error'): error handling is now done by
  the form code.

- 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 #8500 by jseng (modified/simplified): improved usability of editing
  URL aliases.

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

- Updated CHANGELOG.txt.

- Updated the form handling to use form_set_error().  All core modules have
  been updated (almost none have error checking for forms) except the node
  forms ...

- 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.

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

- Code improvements by Mathias: made the path module use drupal_set_message().

- Fixes by Goba: updated help text of mass URL aliasing and fixed escaping problem.

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

- Many excellent news aggregator improvements by Kjartan:
    + Added drupal_http_request().
    + Replaced rssfeeds with OPML feed subscription list.
    + Added support for pubDate.
    + Added support for conditional gets using ETag and Last-Modified.

- Path module documentation updates.

  + 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.

- Introduced a drupal_set_message() and drupal_get_message() function.

  Contributed themes and modules need to be updated:
   - modules: status() is no more; use drupal_set_message() instead.
   - themes: use drupal_get_message() to check for status messages and
     visualize them.
