- Patch #6829 by kika: cleanup of drupal.css.  The patch did not apply 100% cleanly so hopefully everything is well.

- Patch #6947 by Ax: fixed a Doxygen warning, fixed some uninitialized varables.

  (I'm back from vacation.)

- Tiny usability improvement for translators.  Patch by Gerhard.

- Profile module improvement:
   * Made it possible to set certain fields as 'required'.

  To do:
   * Mark them as required visually.
   * Add required fields to the subscription page.

- Patch #6425 by TDobes: made avatars work with private download method.  Added
  user_file_download() function to communicate with the file system layer.

Patch 6523 by Steven:

- Strips the leading / from URLs to match with block paths. The reason is that everywhere else in Drupal, we use URLs without leading slash (e.g. URL aliasing). For consistency we should keep this behaviour everywhere. The replacement uses ereg_replace instead of str_replace, but the expression now only match the beginning of the URI so in fact it's faster, esp. for longer URIs.

- Updates the block docs about path matching: gets rid of leading slash, adds initial matching operator '^' and emphasises the slash behaviour (which was not mentioned anywhere before)

- Replaces the example expression for a negative match. It was horribly broken and odd, the replacement in this patch is correct and simpler.

- Patch #6517 by kika: drupal_http_request() fails to open feed because on PHP 4.1.2.  Also updated file.inc.

  + Updated the _user() hook's "$type == 'view'" case to match the
     "$type == 'edit'" case.  That is, both have to return an associtive
     array of the format array('category' => 'fields').

   + Updated the profile pages to group fields by category.  Made possible
     thanks to the above change.

   + Moved logic out of the theme_ functions.

   + Add a new field type: 'list'.

  We can use this for the 'URL of homepage' field on drupal.org.  URL fields
  are rendered as links and are being validated.

- Profile module improvements:

   + Made it possible to define the page title of the user listing pages.

   + Used form_group()s for the profile administration page.

   + Fixed bug in database/updates.inc.

- Small visual improvement to the profile pages.  I'm still not happy with
  it and looking forward for some help.

- Tracker and forum module improvements!

  Note: the CSS of the tracker page has changed.  Some CSS files still have
  to be updated.
