  ==> This fix requires to run update.php!

TODO:

- Some modules such as the buddy list module and the annotation module in the contributions repository are also using session_register().  They should be updated.  We should setup a task on Drupal.

- There is code emitting '<div align="right">' which doesn't validate.

- Does our XML feeds validate with the charset changes?

- The forum module's SQL doesn't work properly on PostgreSQL.

- Fixed critical bug #1788: cloud module pings too much.  Modified patch by
  Kjartan.

  This update requires some database changes so make sure to run update.php.

- Changed the type of the string fields in the locale table to BLOB.
  This fixes bug #987.  For PostgreSQL this is not required because
  its string comparisons are case-senitive.  Not idea about MSSQL.

- update.php improvements and a grammatical fix from Al.  Thanks.

- Fixed bug in book_prev().  Patch by Andy Colson.

- Book optimizations: updated to use inner joins.  Patch by Andy Colson.
  This should address bug #1373.

  TODO: add index to MSSQL database scheme.

- Fixed a typo in the PostgreSQL database scheme.  Patch by Michael Frankowski.

- Fixed a typo in the MSSQL database scheme.  Patch by Michael Frankowski.

- Removed dependency on "register_globals = on"!  Patches by Michael Frankowski.

  Notes:

  + Updated the patches to use $foo["bar"] instead of $foo['bar'].
  + Updated the INSTALL and CHANGELOG files as well.

- Tiny improvement to the "./scripts/code-clean.sh" script.

- Fixed "undefined variable" warning.  Patch by Ax.

- Applied  Michael Caerwyn's "%s -> %d" patch.

- Changed all occurences of '%d' to %d as suggested on the mailing list.

- Fixed bug #1545: incorrect sequence tables on PostgreSQL.  Patch by Neil.

  In addition, I have updated update.php so it makes the corresponding
  changes for MySQL users.

- Applied modified version of Al's "block delta" patch.  I left out the
  blogroll feature as I think it would get very confusing.  I don't mind
  to add it but it need some thought and documentation as it somewhat
  conflicts with the existing cloud module.

  These changes require you to run update.php.

- Made sure that update.php enables the newly created admin module.
  This should fix the other half of bug #1508.

- Removed some dead wood: we don't need the menu table any more.

- Some fixes and improvements as suggested by Gary.

- Fixed type: "form" -> "forum".  Patch by Ulf Rompe.

- forum: fixed link to new topic
- forum: new topic shows default forum correctly
- forum: first_new is back; the anchor didn't consider multiple pages
- forum: use standard pager, needed some changes/fixes to pager.inc
- forum: some cleanup
- forum: taxonomy hook
- renamed first_new to simply new
- added an optional parameter to pager_query for the count query
- used the optional count param for paging forum topics
- internal change: moving a topic doesn't duplicate the node anymore but just
  changes the forum (term); no change in functionality, and shadow still
  works (suggested by Dries).  This probably also made some queries somewhat
  lighter.
- bug fixed: anonymous users always saw "n (n new)" in the replies column
- updated pager help and moved from _help to phpdoc

- Small improvement to the admin menu based on feedback from Michael.

- Fixed links to admin page.  Added help text.

- Clean URL patch.

- Added an extra parameter to watchdog() which lets you specifiy an "action"
  or "operation" link.

- Made the main page of the administration section show an overview of all
  watchdog entries with such action link.

- Fixed typo in PostgreSQL database scheme.

- Fixed typo.  Patch by Marco.

Patch by Marco:

- rewrote taxonomy_get_tree() for improved performance and cleaner code
- fixed a bug in _taxonomy_term_select() with multiple parents
- added hooks in vocabulary and term insert, update and delete
- fixed a bug in taxonomy_save_vocabulary() (cache_clear_all() was never
called)

- Refactored the administration pages.

- Make sure user names are unique.

Applied patch by Natrak:

- page_header() now adds Last-Modified and ETag http headers.
- When running PHP as an Apache module page_header() will check the HTTP
  headers for conditional gets, and will only push the content when it
  fails. (Works for html and xml pages as they are all cached). Note:
  this is a PHP limitation, so until PHP makes it work for other web
  servers this won't work for them.
- Added created field to cache database to hold the timestamp when the
  cache was created.
- Changed cache_get() to return an object with ->data and ->created.
- Update forum and locale modules.

- Some changes to the update.php script: revised the instructions a bit,
  added some logic and a link to "upgrade 4.0.x to 4.1.x", etc.

- Added missing query to change the session field from VARCHAR(32) to TEXT.
  Reported by Bert Garcia.

- Added Stefan's page module improvements.

  [NOTE: the PostgreSQL database scheme needs updating.]

Patch by Natrak:

- Modules and themes now use the same functions to find and administer
  files.
- Modules can now be placed in sub-directories.
- Theme descriptions can no longer be edited. This will be handled by
  Dries' theme_conf patch.
- Update required to keep old modules enabled.

- Committed Marco's block rewrite:

   + Blocks are not longer called if not rendered: major performance
     improvement.
   + Fixed some bugs (preview option was broken, path option was broken).
   + Removed "ascii"-type blocks.
   + Added permission to for "PHP blocks"
   + ...

  NOTES:

   + You'll want to run "update.php":

       ALTER TABLE blocks DROP remove;
       ALTER TABLE blocks DROP name;

   + You'll want to update your custom modules as well as the modules in
     the contrib repository.  Block function should now read:

       function *_block($op = "list", $delta = 0) {
         if ($op == "list") {
           return array of block infos
         }
         else {
           return subject and content of $delta block
         }
       }

- updated database dump.
- removed tables modules, layout and referrer (don't forget to backup!).

- fixing the statistics module SQL updates so they work for users that haven't
  used the statistics module before.

- Committed Jeremy's incarnation of the statistics module.  Last minutes
  changes include:

    * a couple of coding style changes, renamed some "stats" into
      "statistics", etc.

    * removed the "Who's online" block from the user module.

    * added db_affected_rows() to the resp. database abstraction
      layers and made the statistics module use db_affected_rows()
      instead.

    * added update logic to "update.php".

- Made sure the sequence table is properly initialized for comments.

- Commited Marco's new comment module and forum module!!!
