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

- Patch #5184: fixed block path and aliases.  Patch by Nick.

- Removed the 'enable/disable' setting from the throttle module.  To disable
  a module, disable it from the modules configuration page.

- Comment setting improvements: updated the form descriptions, reorganized the
  settings in groups, fixed a warning, rewrote the comments per page settings,
  etc.

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

 - Cache now stores custom headers.
 - Replace theme_head() with drupal_get_html_head(), added drupal_set_html_head().

- 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?

- Fixed bug #5074: standarized the user log messages.

- Removed some debug info.

/**
 * 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.

- Implemented feature request/bug #4973: removed the throttle module's dependence
  on cron to make adjusting the throttle level more responsive (when configured
  to).

- Fixed bug 4972: an incorrect permission name prevented the throttle block
  from being shown to users.

Added checks to the drupal directory option to display an error when the site name, email, slogan or statement aren't filled in.

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.

- Changed some boxes to fieldsets/lengeds.

- Patch 4948 by Goba: the poll module uses check_output() on the poll options.

- Patch #4924: made the comment form themeable.  Patch by Goba.

- Log the search terms in a new watchdog category.

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

  dynamically and can be extended through the watchdog() call.  (Chris
  could use it to move the cron message to their own category.)

- Patch #4093: only invoke check_output() once for performance's sake.  Patch
  by Goba.

- Re-added STYLE/ON*= filtering (this got lost a while ago due to reorganisation)

- Fixed incorrect filter usage in poll.module
