- Mofified patch #8862 by puregin: improved book module documentation.

- Patch #11600 by jhriggs: the module_load_all() function will currently behave unexpectedly if a module cannot be found (has been removed, renamed, etc). Once one module fails to load, all subsequent modules will not be loaded due to a short circuit condition when performing a boolean AND.

- Patch #11577 by drumm: changed t('ago') -> t('%time ago', ...) to make it
  translatable in languages such as Spanish.

- Fixed bug #11312: menu caching to aggresively.  I did not apply the proposed
  patch but moved the menu-logic to the $may_cache clause and added some checks
  to avoid SQL overhead.  I think this is the most performant solution.

- Patch #10677 by drumm: removed dead code.  Leftover.

Bug: the default filter setup had the wrong filter delta for the linebreak filter. Now it matches updates.inc.

  I rewrote this patch for simplicity.

- Patch #11530 by Frodo: fixed long filter tips.

- Patch #9292 by Gerhard: fixed another array_merge + PHP5 woe.

- Modified patch #10613 by killes: generate a 'page not found'-page when a requested node does not exist.  I modified the patch to avoid duplicate 'not found'-checking in the second bulk.

- Patch #11271 by Ber: fixed form_radios() to generate valid XHTML code.  This makes the code generated by the poll module XHTML compliant.

- Similarly, I updated form_checkboxes() to generate valid XHTML code.

- Patch #11298 by nato: the function _forum_topics_read was not returning only nodes of type 'forum' resulting in the forum overview listing counting all node types as topics; attached patch modifies queries to return counts of only 'forum' type nodes.

- Patch #11431 by Gerhard: made sure no empty strings are exported + replaced some double quotes by single quotes.

- Bugfix: provide an absolute URL to the 'ping servers'.

- Orphaned the node_link() hook as per #9769.

- Code improvement: removed some redundant code from the book module.

- Fixed critical bug #10664: made comment in collapsed mode work.  One more down.

- Patch #11426: the forum module generated an empty table for forums with no child forums.

- Fixed bug #11405: unchecking the "publish" box in the default workflow admin page (admin/node/configure/defaults) did not cause the default workflow to change.  This was caused by the fact that node_validate() forced the value of the status field to "1".

- Bugfix: the filter tips contained a non-existing ID which resulted in invalid XHTML code.

- Bugfix: the filter module generated an empty <ul></ul> (= invalid XHTML) when no filter tips are present.

- Patch #10613 by Gerhard: calling a non-existent username or user ID in the blog module URL now returns a 404 error instead of an empty blog page.

- Patch #4925 by erikhopp: comment module emits too many id="comment"s, so the comment form's one has been renamed to 'comment-form'.  This is also more consistent with the 'node-form' one.
