- Watchdog improvement: added a 'view' link for 'access denied' messages.

  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.

- Patch #13020 by chx: let Drupal handle multiple database layers.

- Removed the PEAR database backend.  It's no longer being used/maintained.

   * Less logic in theme code.
   * Encourages use of the menu system.
   * Easier to find where a title or breadcrumb comes from in other people's code because there are less places to look. Look in menu and then grep for the appropriate set function. Looking for calls to theme_page() is hard because there are too many of them.
   * Very slightly more efficient.

- Refactored the queue module: removed the queue module's field from the node table.  With help from Gerhard.

- Slight addition to INSTALL.txt with regard to PHP versions.

- Updated/reworded some node type descriptions as per Boris' suggestions.

- Adding missing {} around a table name in update.php.

- Patch #13405 by Moshe: make you actually do something useful with the init hook.  A recent patch to 4.5 and HEAD made this patch run too early in the request (for non-cached pages).

   1. Fixed broken watchdog calls: two watchdog calls omitted the type parameter, and thus injected logs into the type field, instead of the message field.
   2. Removed t() functions from user contributed content.

  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.

   + Make bootstrap functionality work with HEAD.
   + Move functions into bootstrap.inc so that statistics_exit() works for cached pages.  (Does this close any issues?)

- Patch #13443 by Moshe: got rid of the semi-implemented 'page link' feature. All themes currently support primary and secondary links so page links are now deprecated.  Check your contributed modules and update them accordingly.

    + added support for multi-site configurations.
    + tidied up some old cruft and added code comments.

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

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

1) Clean up the text analyser: make it handle UTF-8 and all sorts of characters. The word splitter now does intelligent splitting into words and supports all Unicode characters. It has smart handling of acronyms, URLs, dates, ...

2) It now indexes the filtered output, which means it can take advantage of HTML tags. Meaningful tags (headers, strong, em, ...) are analysed and used to boost certain words scores. This has the side-effect of allowing the indexing of PHP nodes.

3) Link analyser for node links. The HTML analyser also checks for links. If they point to a node on the current site (handles path aliases) then the link's words are counted as part of the target node. This helps bring out commonly linked FAQs and answers to the top of the results.

4) Index comments along with the node. This means that the search can make a difference between a single node/comment about 'X' and a whole thread about 'X'. It also makes the search results much shorter and more relevant (before this patch, comments were even shown first).

5) We now keep track of total counts as well as a per item count for a word. This allows us to divide the word score by the total before adding up the scores for different words, and automatically makes noisewords have less influence than rare words. This dramatically improves the relevancy of multiword searches. This also makes the disadvantage of now using OR searching instead of AND searching less problematic.

6) Includes support for text preprocessors through a hook. This is required to index Chinese and Japanese, because these languages do not use spaces between words. An external utility can be used to split these into words through a simple wrapper module. Other uses could be spell checking (although it would have no UI).

7) Indexing is now regulated: only a certain amount of items will be indexed per cron run. This prevents PHP from running out of memory or timing out. This also makes the reindexing required for this patch automatic. I also added an index coverage estimate to the search admin screen.

8) Code cleanup! Moved all the search stuff from common.inc into search.module, rewired some hooks and simplified the functions used. The search form and results now also use valid XHTML and form_ functions. The search admin was moved from search/configure to admin/search for consistency.

9) Improved search output: we also show much more info per item: date, author, node type, amount of comments and a cool dynamic excerpt à la Google. The search form is now much more simpler and the help is only displayed as tips when no search results are found.

10) By moving all search logic to SQL, I was able to add a pager to the search results. This improves usability and performance dramatically.

- 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 #11271 by Ber: fixed form_radios() to generate valid XHTML code.  This makes the code generated by the poll module XHTML compliant.

- Similarly, I updated form_checkboxes() to generate valid XHTML code.

- Simplified/reorganized version of patch #9620 by Jeremy: fixed errors when writing to cache.

- Made it possible for the i18n module to hook in.

Replace hardcoded <html lang="en"> with a locale dependant one. This is especially important for asian sites where this has an effect on font selection.

- Patch #10663 by JonBob: documentation improvements: fixed some typos and improved consistency to the use of Doxygen/api.module commands in the comments.

- Patch #6809 by TDobes: fixed the textarea hook so WYSIWYG editors are made possible again.

  TODO: apply the documentation and htmlarea module patches.

- Patch #10166 by jvandyk: bugfix: valid_url() believed that URLs with encoded spaces in them (eg. http://example.org/my%20file.html ) are not valid.

- Patch #10195 by JonBob: bugfix: common.inc used the function ob_get_clean() which is only available in PHP >= 4.3.

- Theme system changes.  Please consult http://drupal.org/node/view/9576 for details.

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

- The upload (filehandler) module has landed!
