- Patch #144634 by chx: fixed critical bug that prevented language negotiation to work after/when drupal_goto() is called.

#176805 by dww: conditional linking to dblog pages in update.php, so if the module is not enabled, we don't get broken links

- Patch #179937 by quicksketch: made the table header magic more robust.  When a table disappears from the HTML, an error would otherwise be thrown.

#179474 by JirkaRybka and pwolanin: proper depth counting for menu tabs when parents are missing inbetween

#178999 by sammys: register header(Location) as a shutdown function in drupal_goto() so the redirection takes place after the session data was written to the database

#104662 by chx: the search block form might not be available on the search page itself, so that target was not right for search block form submissions

#86857 by pwolanin and webchick: autogenerate log message for book page changes when made from the outline view (ie. node title or weight can be changed and is now in the log message)

#176141 by yched and myself: only print install page layout, if there is some output to send to the user. If JSON output is generated, it is already printed and should not be themed with HTML.

#148084 by yhager: two missing images from the RTL pushbutton support file set (while the RTL sheets are still in development)

#168620 by hass: remove extraneous @charset rules from the compressed CSS files, because Safari chokes on them. Actual testing was done at #150759

#90570 by bdragon and chx: GET query and fragment information were not possible to define in menu links

#167284 by Heine and pwolanin: proper field type placeholders in IN() queries, setting a best practice to avoid vulnerabilities

#158927 by John Morahan: first time, the default admin theme name is '0', so block initialization gives warnings. Avoid this initialization until we have a theme selected

- Patch #135926 by mooffie: hook_link is called by the wrong parameters.  Fixed disconnect between node_view() and hook_link().

#145251 by chx: document that one needs to include the proper 'op' value in arrays passed to drupal_execute() to trigger the right action

#177829 by jjeff: search indexing did not invoke the nodeapi alter hook, so what the user seen and what was indexed was different

#177927 by chx: use path=/ in PHP comment settings cookie creation, so cookies set around the site are available in other 'directories'

#177906 by douggreen: JavaScript cookie detection should use path=/ to avoid broken situations when run at a 'subdirectory'

#160043 by chx: array_filter for book admin settings form, which is required based on http://lists.drupal.org/pipermail/development/2006-September/019917.html
