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.

     <dcterms:modified>.

     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.

- Many excellent news aggregator improvements by Kjartan:

/**
 * 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.

- Committed phase 4 of JonBob's menu system changes.

- Patch by JonBob:

  Phase 2 of the menu system integration project. This unifies the interface
  used by admin and non-admin pages, and deprecates the _page hook in favor of
  explicit callbacks from menu(). Breadcrumbs, titles, and help text go away
  as a result of this patch; they will return in the phase 3 patch, printed
  by the theme.

- Fixed theme glitch.

- table(...) -> theme("table", ...)

- Committed stage 2 of the theme system improvements!  Patch by CodeMonkeyX.

- Improvement: made it possible to disable the comment controls and reworded some of the configuration settings.

- Improvement: removed a left-over from Drupal 4.2.0 (dead code).

- Improvement: replaced hard-coded XHTML around the XML icons with class="xml-icon".

- Improvement: removed the custom navigation menus shown at the top of the "user information page" and integrated them in the new navigation block.  The "my account" link in the navigation menu will unfold.  Also removed the "delete account" link/functionality (for now).

- Improvement: fix for "magic quotes" settings.  Patch by Steven.  I also removed check_php_settings().

- Improvement: block themability improvements.  Modified patch from Ax and Steve/CodeMonkeyX.

- Fixed bug #2617: editing user information does not work.  Patch by Kjartan.

- Small documentation improvements.
