#352121 by valthebald, Damien Tournoud, mr.baileys: The safe string check on translations should only be applied to the default textgroup. Strings in other textgroups such as blocks and menu items are displayed via escaping and filtering, and might contain arbitrary HTML.

#329797 by berenddeboer, redndahead, danielb: The tablesort code did not account for possibly nested tables; only match immediate descendats, so elements of nested tables are not matched.

#455172 by budda, RoboPhred, andypost: Fix drupal_mail() documentation, so that it encourages to set the body of the email as an array (like core does).

#461938 by grendzy, JamesAn: Use filter_xss_admin() on site name and site slogan, just like footer message and mission

#339466 by patryk, c960657, alexanderpas: Remove url() wrapping from remote links and link in a more user friendly OpenID provider list.

#243253 by Benjamin Melançon, dww: Update status should not attempt to request update data until a limit is reached. Fixed Drupal instances when drupal.org is down and gets less load on Drupal.org if data is not found.

#236657 by hctom, swentel: In system_clear_cache_submit(), the function arguments were swapped (but it did not affect how it actually worked).

#373225 by jpulles, Josh Waihi: When changing columns, PostgreSQL needs explicit type casting to ensure that values are kept properly.

#145733 by kepten, brianV: The session.use_cookies PHP setting is required by Drupal, but it can be turned off, so try to ensure it is turned on at all times.

#197266 by ufku, lilou, Dave Reid, c960657, drewish: Save a query by only calling file_space_used() when a limit is provided.

#482646 by Dave Reid: For proper HTTP query simpletesting, we should pass on the instance identifier (database prefix).

#226479 by gpk, BrianV, catch: We should always show the node access rebuild button. The check on when to show it was fragile, so the button might not have been there when actually needed.

#246096 by Sutharsan, Pedro Lozano, mr.baileys, andypost: Actions set to run on cron were not actually triggered.

#465190 by Heine: The Anonymous name is a plain text setting, so it should be escaped properly for output.

#398902 by Nick Urban, alexanderpas, kscheirer: password equality checking was not using strict type checking; we should assume these are strings and compared character to character

#460420 by wulff, andypost: drupal_set_title() in forum_overview() is not needed; menu already sets the title and is localized

#468732 by andypost: cache_clear_all() mentioned cache_flush_delay incorrectly; it should say we use cache_lifetime

#452704 by andypost, catch: Names of compressed CSS and JS files should have a prefix, so that names starting in ad* will not happen. Those are easily blocked by firewalls, Firefox's Adblock, etc.

#454992 by sun, bengtan: _drupal_flush_css_js() should not have 'q' as a possible CSS query character, since that is the Drupal path name character too

#193577 by Rob Loach, Damien Tournoud, andypost: JavaScript string split() function does not behave like PHP explode(); causes problems with multiple node body break tags

#448268 by dww: Make sure that submitting the themes admin form clears out the update status cache, just like the modules admin form does.

#292565 by grendzy, John Morahan, Jody Linn: remove path munging on 403/404 pages, which caused problems for login redirects

#239945 by Xano, JeremyFrench, Damien Tournoud, andypost: Should not iterate over the children in taxonomy_get_tree() anymore if we reached max_depth.

#353328 by catch, BrianV: When a new commment is added, the redirection path should point to page, where the new comment is.

#220592 by dww and pwolanin: Always use the database for caching in update module, so that drupal.org project data persists. Improves both local and drupal.org site performance.
