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

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

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

- 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.

- Changed 1100+ double quotes to single quotes.

- Patch #5575 by Stefan: fixed invalid XHTML code in the node and taxonomy module.

- Patch #5526 by Kjartan: cleaned up node_page(), show a 404 when the node
  could not be found.

- Patch 5049 by JonBob: allow a module to define multiple node types.

- Patch #5393 by Goba: changes the search hook return value, and requires an array
  containing two elements, the first being the requested title, and the second being
  the result list. Advantages:
    * Cleaner search code in common.inc
    * Po extraction is possible and works fine
    * No hardcoded exceptions for node and comment modules, since any module can
      return results in order of relevance (or another order)

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

- Removed the $help parameter from the _form hook.  The help, typically
  submission guidelines, should be emmitted using the _help hook.

 - Adds drupal_set_header() and drupal_get_headers().
 - Cache now stores custom headers.
 - Replace theme_head() with drupal_get_html_head(), added drupal_set_html_head().
 - Added RSS autodiscover links to node, blog and taxonomy pages.

- Patch 4859: new drupal_unpack() consolidates duplicate code and makes it
  easy to show avatars next to nodes and comments.  Patch by Moshe.  As a
  showcase, maybe Xtemplate should have an option to enable/disable avatars?

- Applied patch #4949: node_prepare() wastes resources.  Patch by Goba.

Round 3 of aggregator improvements:

 - Added support for new tags:
   + Optinal feed image: <image> tag.
   + Dublin core dates: <dc:date> <dcterms:created>, <dcterms:issued>,
     <dcterms:modified>.
 - Usability improvements:
   + On the administration page, made the feed/bundle titles link
     to the feeds/bundles' pages.  On the feed/bundle's page, made
     the 'Last updated' field link to the administration page.
   + Moved the 'syndication' menu one level down.
 - Updated some content sensitive help.
 - Further improved themeability.
 - Fixed some invalid HTML.

- Fixed bug #4965: typo in the help text.

Committed filter separation patch: all filter-related things are now in filter.module (which is a required module).
To do this cleanly, I reorganised some bits of system.module: there is now a generic handler available for simple variable-get/set based configuration pages. Look at filter_admin() or system_view() for example usage.

(based on the patch by Goba)

- Patch 4916: improved preparation of $node->teaser and $node->body.  Patch by
  Goba.
