- #41940: Locale string search broken in some cases (and remove some inappropriate db_escape_string() usage)
- #43491: Missing drupal_goto() after saving settings

  TODO:
  + The contact.module was broken; a new patch for contact.module is needed.
  + Documentation is needed.
  + The most important modules need to be updated ASAP.

  for performance's sake.

  TODO: we should write down a couple guidelines for these document them in
        the PHPDoc code of drupal_set_message()!  .

- Patch 20910 by chx: centralize print theme page.

  We added a 'severity' column to watchdog():
    watchdog($type, $message, $link) --> watchdog($type, $message, $severity, $link);

    * Specify a severity in case you are reporting a warning or error.
    * The $link-parameter is now the fourth parameter instead of the third.

  TODO: document this in the upgrade guide.

- Bug 13503: updating the locale settings might impact the interface (eg. menu's) so we have to flush the cache.

- Patch 13180 by chx: renamed check_query() to db_escape_string() and implemtented it properly per database backend.

  Read the manual for pg_escape_string:  "Use of this function is recommended instead of addslashes()." Or read sqlite_escape_string: "addslashes() should NOT be used to quote your strings for SQLite queries; it will lead to strange results when retrieving your data."

- Patch #11728 by Uwe Hermann: fixed some typos in the code comments, Doxygen documentation and screen output.

  Uwe: I dropped the 'iff' chunks as 'iff' stands for 'if and only if'.

- Patch #11179 by stefan: fixed broken URL in context sensitive help.

- Patch #8179 by JonBob: reintroduced menu caching.

- Moved some documentation around and fixed a missing translation.

- Fixing broken .po import (due to file.inc changes).
- Do not show error notice on import page when no languages have been added (no longer necessary due to ability to add-and-import in one step).
- Added a notice about importing possibly taking a while.
- Raised the PHP execution time limit for importing (if not in safe mode, similar to cron.php).

- Patch by JonBob: for consistency and readability, add brief descriptions of each source file inside the @file comment block at the head of the file. This helps with Doxygen indexing, and also allows neophytes to see what a file does immediately on opening the source, regardless of the organization of the hooks.

- Code improvements by Stefan: made all status messages consistent (and easier to translate).

- Patch #9983 by Stefan: various code style improvements.

- New locale module thanks to Gerhard, Goba, Marco, Kristjan and others.

  The new locale module provides every functionality on the web interface, so you don't need to edit the configuration files or add columns, when you add a new language. This module is an integration of the old locale and localegettext modules, plus a bunch of logic to parse Gettext Portable Object files (opposed to Machine Object files, as supported by localegettext).

  Note: I made some minor changes to the context-sensitive help texts and to some of the status messages.

More functionality, less code.  Here is a list of the changes:

- Some user API changes:
   + When $type is 'form', you have to return an associative array of groups.  In turn, each group is an array with a 'title', 'data' and 'weight'.
   + A new $type has been added, namely 'categories'.  User settings can be organized in categories.  Categories can be sorted, as can the groups within a category.  (Ordering 'categories' is somewhat broken due to a bug in the menu system.)

- The 'my account > edit' page will use subtabs for each 'category'.  Read: you can break down the account settings into multiple subpages.

- Profile module improvements:
   + Added support for private fields to the profile module!
   + Improved workflow of profile administration pages.
   + Improved the form descriptions.

- Code improvements:
   + Unified user_edit() and user_admin_edit().
   + Unified and cleaned up the validation code.  Fixed some validation glitches too.

Tabs patch!

CHANGES
-------

 + Introduced tabs. First, we extended the menu system to support tabs. Next, a tab was added for every link that was (1) an administrative action other than the implicit 'view' (2) relevant to that particular page only. This is illustrated by the fact that all tabs are verbs and that clicking a page's tab leads you to a subpage of that page.

 + Flattened the administration menu. The tabs helped simplify the navigation menu as I could separate 'actions' from 'navigation'. In addition, I removed the 'administer > configuration'-menu, renamed 'blocks' to 'sidebars' which I hope is a bit more descriptive, and made a couple more changes. Earlier, we already renamed 'taxonomy' to 'categorization' and we move 'statistics' under 'logs'.

 + Grouped settings. All settings have been grouped under 'administer > settings'.

TODO
----

 + Update core themes: only Xtemplate default supports tabs and even those look ugly.  Need help.

 + Update contributed modules.  The menu() hook changed drastically.  Updating your code adhere the new menu() function should be 90% of the work.  Moreover, ensure that your modue's admin links are still valid and that URLs to node get updated to the new scheme ('node/view/x' -> 'node/x').

- Making sure profile fields are saved properly.

- Added support for 403 handling.  Patch by JonBob.  As a side benefit,
  administrators will be able to define a custom 403 page, just as they
  can define 404 pages now.

  This needs to be documented in the "Changes since / migrating to ..."
  pages.
