- Made the recent news items page, the source pages and the categorization
  pages use pagers.  Removed the 'Items per page' setting and made Drupal
  remember news items much longer.

- Code improvements by JonBob.  Thanks again.

- Fixed feed status not being reset when items are removed.

- Various aggregator module improvements.  Modified patch by drumm.

- 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.

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

- System: the 404 setting instructions advise using 'node', this should be '' (redirecting the user to the front page without any message whatsoever is confusing)

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

- Patch 5592 by Goba: let drupal_map_assoc() rule.  :-)

- Renamed CHANGELOG to CHANGELOG.txt for Windows uses.

- Fixed bug #5628: wrong timestamp in aggregator.  Patch by BartJ.

- Fixed bug in image parsing: caused 'Array' to be printed on the screen.

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

- Patch 5330 by Adrian: PostgreSQL updates and fixes.

- Patch 5256: code improvements: theme('header') + theme('footer') -> theme('page').
  Patch by Gerhard.

- Reworked error/status reporting in the aggregator module to fix a bug.

 - 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.

- Removed some debug info.

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.

 + Added some a new theme fucntions to the aggregator to make it possible to
   theme the aggregator page.
 + Removed the <table> and much hardcoded CSS as well as theme("box")-es.
 + Added the aggregator's theme functions to Doxygen's themeable group.
 + Added breadcrumb trails to the aggregator pages.
 + Updated the core themes to take advantages of the improved themeability.

- 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.

- Added proper access checking to block and menu items.

/**
 * Wrapper around xml_parser_create() which extracts the encoding from the XML
 * data first and sets the output encoding to UTF-8. This function should be
 * used instead of xml_parser_create(), because PHP's XML parser doesn't check
 * the input encoding itself.
 *
 * This is also where unsupported encodings should be converted.
 * Callers should take this into account: $data might have been changed after
 * the call.
 *
 * @param $data The XML data which will be parsed later.

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)

(sorry last commit, I promise :P)

Added a short piece of code that does this.
(see drupal.org's Drupal Talk to see this bug in action)

- Removed the import module's custom menu.  Added a 'news aggregator' menu to
  the navigation block.

- Translation fixes: fixed three usages of format_interval().  Patch by Goba.

- Updated the calls to menu() to use MENU_HIDE instead of 1

- Excessive CSS tags were generated for feeds and bundles.

  TODO: get rid of the custom import specific navigation menu.

- 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.
