  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.

  Usernames can now be themed; eg. an icon/avatar could be added.

  TODO: update contributed modules + update the migration docs.

- Patch 20910 by chx: centralize print theme page.

  Less is more.

- Patch #15957 by Goba: reintroduce translateable watchdog types.

  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.

- Fixed colspan bug reported by Steven.

- Fixed typo and reworded the filter.

  changes are:

  1. Simplified the statistics pages: there are less pages and on the
     remaining pages there is a lot less visual clutter (less columns and
     better presentation).

  2. Reorganized the 'administer - logs' menu: flattened the menu structure
     and removed a number of links.

  3. Improved performance.  Most statistics pages used about 160 slow SQL
     queries which made the statistics pages fairly unusable on my system.
     The new pages use at least 10 times less SQL queries and render much
     faster.  They are actually usable.

  4. There is now a 'track'-tab on node pages, and a second subtrab on the
     user accounts 'track'-tab for people with the 'access statistics'
     permission.  They can be used to resp. track the node and the user.
     This makes the statistics more accessible.

  5. Changed the way watchdog messages are filtered.  This makes it easier
     to introduce new watchdog types.

  6. Reworked the statistics module's permissions.

  7. Less code: 223 insertions(+), 343 deletions(-).

  8. Fixed several glitches: for example, the statistics pages sorted the
     'Name' column by user ID instead of by name.  Unfortunately, it is
     too difficult to backport these to DRUPAL-4-5.

  TODO:

  1. Review the statistics modules help pages.

  2. Help fine-tune the interfaces/views.

  NOTES:

  1. You'll want to run update.php.

- 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."

- Added generic flood control mechanism to throttle certain operations per hostname (eg. posting comments, requesting passwords, sending e-mails).  See flood_register_event() and flood_is_allowed() for details.

- Patch #12455 by Steven: optimized SQL query.  This problem caused Drupal.org's
  cron runs to time out.

- Patch #8179 by JonBob: reintroduced menu caching.

#10648: Fix watchdog-related tablesort coloring bug in IE, add support for <tr> attributes to theme_table() and reduce specificy of watchdog coloring CSS rules.

- 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: use capital letters for header titles (and added some missing t() functions).

   * Adds missing quotes around the username in "session closed" watchdog messages from user.module (session opened has quotes, but session closed does not).
   * Changed "view detals" after watchdog entries to "details".

- 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 #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.

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').

- 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.

- Patch 6675 by Ax: reorganized the menu's of the watchdog and statistics module
  to be more intuitive and moved some help text to Doxygen comments.

  configurable!  Menu items can be disabled, repositioned, added and
  so on.

  Upgrading to requires you to run update.php.

  This functionality depricates some of the 'navigation modules' in the
  contributions repository.  Furthermore, modules can now 'suggest'
  menu items and site adminstrators can choose to enable them.  Modules
  in the contributions repository should try to take advantage of this.

Truncate UTF-8 patch. Introduced a new function truncate_utf8() for chopping off strings at unsure locations, without risking incomplete UTF-8 data.

- Patch by Steven: removed redundant permission checks.  These are no longer
  required thanks to the new 404 handling.

- Patch 5592 by Goba: introduced a new function, drupal_map_assoc().

- Avoid SQL queries if possible.

- Usability improvement: changed 'messages' to 'logs'.

Patch 5287 by Stefan: multiline help texts should become inside a single $output.
