- Usability improvements: reworked/simplified the timezone/date settings a
  little and made the form groups use consistent titles.

- Usability: improved the error reporting of the file system settings on the
  'home » administer » settings" page.

- Bug #8823: fixed typo: '..' -> '.'.

- I'm removing these files from core: they belong in contrib/docs/marketing
  now (if they are not already there).

- Improved the error/status reporting in Chameleon: made the messages
  stand out a bit better by using green-ish and red-ish colors, resp.
  for 'success' and 'failure'.

- Small change to the way context-sensitive help texts are emitted -
  the pages wouldn't validate in the presence of help texts with
  block-level elements.

- Patch #8975 by drumm: remove block placement preview.  Most themes, if not all the commonly used ones, can handle blocks on either side, and there is no way to see the preview without saving and seeing the results on the site.

  Anything else that can be removed?  Less is more.

- Patch #4166 by daBrado: don't show the profile fields when the user does
  not have the 'access users' permission set.

- Patch #8382 by jseng/junyor: allows autodiscovery of BloggerAPI via RSD.

- Patch #9031 by Ber: if the comment module is not available comment_num_all()
  should not be called.

- Patch #9049 by JonBob: fixed a number of tab issues.

- If you are allowed to vote, results are now shown on a separate node tab "node/id/results".
- Poll voting now submits to a separate URL and uses drupal_goto to go back to the poll node

- Updated node.module to use drupal_goto after submission: this allows people to refresh after submission without any problems.

- Patch by Steven and me: refactored the form handling of nodes. The node system is now using form_set_error() and friends like the rest of Drupal does. This makes for both a consistent user experience and consistent code. It simplifies the forms and validation code, however, it does change the node API slightly:

    * The _validate hook and the _nodeapi('validate') hook of the node API (1) no longer take an 'error' parameter and (2) should no longer return an error array. To set an error, call form_set_error().

    * The _form hook of the node module no longer takes a form hook and should not worry about displaying errors. Ditto for _nodeapi('form_post') and _nodeapi('form_pre').

- Made it possible to edit blog posts and made the blog module use tabs.

- Patch #8952 by Morbus: watchdog module beautifications.

  * slightly reorders the functions in anticipation of http://drupal.org/node/view/9010.
  * reorders help definitions to match the alphabetical nature of the menu items.
  * tweaked visual appearance of menu code (whitespace, etc.)
  * minor tweaks to "warning" help to match style of others.

- Patch #9006 by Killes: For some reason there is a array_merge that nobody seems to need. It generates an error under php5. Found by redLED.

- Patch #8973 by JonBob: Drupal contains many undefined variables and array indices, which makes PHP throw a lot of warnings when the reporting level is set to E_ALL. Things run fine with these warnings, but as a matter of code style if nothing else we should probably strive to avoid them. The attached fixes most of the more egregious offenders (about 95% of the warnings when I load /node on my test site).

- Patch #8952 by Morbus: made the watchdog module more doxygenish:

   * @file header with a oneliner and blurb description about watchdog.module.
   * standardized the text between admin/help#watchdog and admin/logs.
   * tweaked the descriptions of log types available ever so slightly.
   * removed anything that referred to the old settings page.
   * added an assumed 'type' to one of the menu's.

- Patch #8941 by JonBob: allow local tasks to be ordered by weight, as well
  as simplifying the theming of local tasks so they can be more easily
  rendered in a non-tab manner.

- Bug #8898 by Morbus: fixed incorrect date being displayed in the forum overview when a topic has no comments yet.

- Fixing some usability bugs with aggregator admin: some forms lacked status messages, and redirected to themselves
- Now uses drupal_goto after every form submission [1]. Patches for other modules will follow.

[1] http://lists.drupal.org/archives/drupal-devel/2004-06/msg01147.html

- Preventing caching of page when status messages are present (needed for redirects after form submission to work properly)
- Double-quotes to Single-quotes

- Fixed 'pass by reference'-bug in the validation code and further simplified
  it.
