- Patch #10990 by TDobes: adds a "create new blog entry" link at the top of each user's own blog page, similar to the "post new forum topic" link displayed at the top of forum pages. This adds consistency as well as convenience for users.

- Patch #6166 by Moshe: node preview should not display links.  Push the links to the theme instead of the theme having to pull them in using node_link().

  TODO:
    1. Update theme upgrade instructions in the handbook: node_link() is gone.
    2. Remove page_link() just like we removed node_link().

- Patch #12363: fixed glitch in user_access() as pointed out by TDobes.

- Patch #13334 by Axel: added a simple script to prefix a database scheme.

- Patch #13263 and #13265 by arnab: added word-based truncation and made the comment module use it to extract subjects.

- Removed hardcode font size from drupal.css as per #13095.

- 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."

- Caching index statistics
- Minor code cleanup

- Patch #8506 by Gerhard: added basic node_load() caching.

- Adding the missing flood tables.  Sorry.

- 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.

- Modified patch #8552 by Gerhard: added 'add child page' link to book pages you can edit.

- Modified patch #7235: do a better job checking the OS and acting upon it.

  the configuration file.

- Patch #12353 by Stefan: usability improvement: don't show 'throttle fields' unless the throttle module is enabled.

- Patch #12783 by Stefan: various small consistency/usability improvements.

- Patch #12885 by Ber: improved the Doxygen documentation of drupal_set_html_head().

- Patch #11977 by matteo: taxonomy_term_count() did not take node-level permissions into account and could return an incorrect number.

- Patch #11940 by kps: if the user is not allowed to view a newly submitted node, redirect him to the main page.

   + throttle module: flush cache when the throttle enables/disables
   + throttle module: prevent throttle being enabled by 0 users or guests when disabled
   + system module: remove requirement for statistics.module
   + block module: update help text to reflect access log is no longer required
   + statistics module: throttle is now enabled/disabled, not using levels 0-5

- Patch #12886 by thorne: fixed XHTML problem: the bluemarine theme used a border=0 attribute on the img tag for the site logo.

  * There are only two throttle levels instead of 5, namely 'enabled' and 'disabled'.  This makes it a _lot_ easier to predict when the throttle will kick in.  However, if you maintain a module that is throttle-aware, it needs to be updated!

  * The throttle mechanism now uses the current number of anonymous users or the current number of authenticated users to kick in.  This is a _lot_ more intuitive than the old throttle mechanism.

  * The throttle block has been removed -- you can now use the "Who's online" block to determine the good throttle settings.

  * Most of the documentation has been removed because it was deprecated.

  * It's less code!

- Performance improvement: made 'sid' the primary key of the sessions table.
  That should improve performance of session handling as well improve
  performance of the "Who's online"-block.  Drupal.org's sessions table
  contains appr. 40.000 sessions on a slow day and rendering the "Who's
  online"-block became a performance bottleneck.

  This change has yet to be tested on a busy site so things might go wrong.

- Patch #11427: added 'edit own forum topics' permission.

- Patch #12658 by menesis: when an administrator adds a user, the 'authenticated user' role was not assigned to the new user.

- On popular demand, patch #10178 by jhriggs: made it possible to expand menu items.

- Patch #11871 by killes: forum topics could be displayed multiple times when node-level permission were used.
