  you logged out.  Patch by Jeremy.

- Bugfix: fixed the authmap table in the MSSQL scheme.  Patch by Moshe.

- Bugfix: properly themes some error messages in the user module.  Patch
  by Moshe.

- Bugfix: increased the size of variable's tables the 'name' field.  Patch
  by Gerhard.

- Bugfix: don't set a name and e-mail address for the anonymous user.  Fixes
  bug #3740.

- Bugfix: renamed the 'statistics' table to 'node_counter' as 'statistics' is
  a reserved SQL keyword.  Required for both PostgreSQL and MSSQL.  Patch by
  Adrian.

- Bugfix: renamed the 'path' table to 'url_alias' as 'path' is a reserved SQL
  keyword.  Required for both PostgreSQL and MSSQL.  Patch by Adrian.

- comment.module: fixed an ambigous 'timestamp' query

- forum.module: prev/next links no longer excerpt from the title+body in
their title attribute. they now excerpt from only their title. this is
more consistent with rest of drupal, and GROUP BY on node.body which
isn't appreciated by MSSQL. also replaced some '' with NULL which caused
errors in MSSQL

- statistics.module: replaced a USING join with a standard ON join. USING
is not as widely supported, and functionally equivalent.

- Fixed translation bugs with statistics module.  Patch by Gabor.

- Removed 'homepage' field from user table.  Patch by Gabor.

- Added 'real name' field to the profile module.  Patch by Gabor.

- Patch by Bart Jansen:

  <quote>

  This adds session support for anonymous users and fixes a bug/typo.

    1. changed rid for user #0 from 0 to 1 (rid 1 == anonymous user) to make
       inner join work.

    2. replaced "if ($user .." by "if ($user->uid .." because now $user is
       always set (my previous change probably caused this).

    3. db_next_id("user_uid") -> db_next_id("users_uid");
  </quote>

  I repeat:

  "This adds session support for anonymous users and fixes a bug/typo."

- Gerhard's uid 0 patches.  These patches bring various performance
  improvements.  Requires a database update.

- Small bugfix for the database.mysql sql structure with the new indexes
  introduced in yesterday's forum query patch.  Patch by Matt.

- Tested and committed Kjartan's performance patches.  (Fixed the access check
  in update.php though.)

  PostgreSQL and MSSQL database scheme as well.

- Made sure the update script updates the correct tables when database
  prefixing is enabled.  Patch by Bart Jansens.

- Improved the breadcrumb navigation of the book and the forum module as per
  Keith Instone's suggestions.

- Updated page titles (or block titles) and links to match.  Suggested by
  Keith Instone.

- Added missing 'thread' field to the comment table of the MySQL database scheme.
  Fixes bug #2590.

- Fixed typo in database.pgsql.  Patch by Michael.

- Fixed braino in PostgreSQL database scheme.

- Fixed braino in MySQL database scheme.  Patch by Gerhard.

- Committed Jeremy's session patch: this brings us one step closer to having
  session for anonymous users.

- Fixed typo: 'vharchar' -> 'varchar'.  Patch by Michael Frankowski.

- Committed Marco's comment module patch:

    + Dramatically improves performance of large discussions/threads: only
      very few SQL queries are required.
    + Replaces custom pager with standard pager.

  Modifications by me:

    + Reworded some code comments.
    + Removed dependencies on pager internals.

- Changing the node body to type 'mediumtext'.  Addresses bug #2155.

- Commited the URL aliasing patch.  Thanks Matt.

  This update requires you to run update.php!

- Bugfix: fixed the CREATE FUNCTION in database.mssql as it needs to be prefixed with GO for some obscure reason.  Patch by Kjartan.

- Bugfix: fixed the defaults for blocks in database.mssql so the NOT NULL fields get values.  Patch by Kjartan.

- Bugfix: changed check_form() to use htmlspecialchars() instead of drupal_specialchars() as this caused Drupal to emit incorrect form items in presence of quotes.  Example:

  <input type="submit" class="form-submit" name="op" value="Submit "top nodes" block changes" />

  IMO, drupal_specialchars() is better called xmlspecialchars() to avoid confusion.

- Bugfix: when an anonymous user visits a site, they shouldn't see any content (except the login block, if it is enabled) unless they have the "access content" permissions.  Patch by Matt Westgate.

- Improvement: improved the error checking and the error messages in the profile module.  Updated the code to match the Drupal coding conventions.  Modified patch from Matt Westgate.

- Improvement: don't generate the <base href=""> tag in the base theme; it is already emitted by theme_head().  Patch by Kristjan.

- Improvement: don't execute any SQL queries when checking the permissions of user #1.  Patch by Kjartan.

- Improvement: made a scalable layout form that works in IE and that behaves better with narrow themes.  Part of patch #51 by Al.

- Improvement: removed some redundant print statements from the comment module.  Modified patch from Craig Courtney.

- Bugfix: renamed the SQL field 'types' to 'nodes' because 'types' is a reserved keyword in MySQL 4.  This fixes critical bug #1618.  Patch by Marco.

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

- Bugfix: made sessions work without warnings when register_globals is turned off. The solution is to use $_SESSION instead of session_register().  This fixes critical bug #1797.  Patch by Marco.

- Bugfix: sometimes error messages where being discarded when previewing a node.  Patch by Craig Courtney.

- Bugfix: fixed charset problems.  This fixes critical bug #1549.  Patch '0023.charset.patch' by Al.

- Code improvements: removed some dead code from the comment module.  Patch by Marco.

- Documentation improvements: polished the node module help texts and form descriptions.  Patch '0019.node.module.help.patch' by Al.

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.

- 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.

- Added default table values to MSSQL database scheme.  Patch by Moshe.  Fixes bug #1571.

- 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 the admin menu is enabled after a fresh install.  This is
  required to make the menu show up.

  This partly fixes bug #1508.

- Some MSSQL related fixes by Moshe.

- Added missing tid-column to the forum table.  Patch by Anarcat.

- Added missing 'created' field to 'cache' table.

- All LIMIT queries must go through the pager or through db_query_range().
  The syntax for db_query_range() was enhanced so it matches db_query(). So
  you may pass extra arguments of the SQL statement which are checked via
  check_query() and then substituted into the SQL statement. After these
  optional arguments, you always pass $from and $count parameters which
  define your range.  Most often, the $from is 0 and the count is the max
  number of records you want returned.  Patch by Moshe.

- The pager_query() function for PEAR was enhanced so that it adds  proper
  GROUP BY statement counting the number of records to be paged. Patch by
  James Arthur.

- MSSQL database scheme by Moshe.

- Added a database scheme for Microsoft's SQL server.
