#363013 by mannkind: Use getwd() rather than realpath(__FILE__) to determine drupal root, so we don't break symlinks.

- Patch 42498 by m3avrck: unified cron-trackers and added a section that lets you figure out whether cron is running (usability improvement).

  for performance's sake.

  up the documentation a little.

  chx: can you double-check whether the global $conf variable is secure?
       (That is, make sure it can't be send using the URL or something.)

  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.

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

- 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.

- Patch #9983 by Stefan: various code style improvements.

- #1322: Adding a warning if the cron fails to complete.
- Simplifying odd commenting syntax

- Removed the hard-coded list of watchdog types.  The list is compiled
  dynamically and can be extended through the watchdog() call.  (Chris
  could use it to move the cron message to their own category.)

- Improved module loading when serving cached pages.  Moshe's bootstrap patch.

- Used legend and fieldset tags for the configuration page.

- Tidied up the usage of module_invoke() and module_invoke_all().  Patch by
  Jonathan Chaffer.

- Made cron.php add a watchdog entry upon completion.

- A large batch of updates, amongst them a rewritten node system.  More
  information available on the mailing list.

  easier. Also changed the <? tag to <?php in some cases.

- node.module:
    + added missing t()-functions (reported by Nick).

- locale.module:
    + renamed '$lang' to '$language' (reported by Nick).

- cron.php:
    + potential improvement (thanks KJ)

CHANGES:

- Rewrote the cron system.  Removed cron.module and moved all cron
  related options to settings.module.  Cron was a confusing thing:
  it has been made simpler both in terms of code and configuration.

   + You had to rehash your modules to make the cron show up in
     the list.  This is no longer required.

   + You couldn't tell what cron "watchdog" or cron "story" were
     up to.  Instead, we now display a clear description message
     for every cron involved.

   + The user interface of setting.module - and the admin section
     in general, looks a bit ackward but I couldn't care less and
     don't want to see this improve at the time being.

- Improved setting.module:
   + Now uses variable_set().
   + Added some help and documentaition on how to setup cron.

- Improved ./export.

- Updated CHANGELOG.


TODO:

- I'm now going to look into UnConeD's question with regard to
  check_output() and $theme->node(), as well as the filter and
  macro stuff.  I'll probably be fine-tuning setting.module a
  bit more on my way.

- Uhm.  Rewrote the module system: less code clutter, less run-time
  overhead, and a lot better (simpler) module API.  I had to edit a
  LOT of files to get this refactored but I'm sure it was worth the
  effort.

  For module writers / maintainers:

  None of the hooks changed, so 95% of the old modules should still
  work.  You can remove some code instead as "$module = array(...)"
  just became obsolete.  Also - and let's thank God for this - the
  global variable "$repository" has been eliminated to avoid modules
  relying on, and poking in drupal's internal data structures.  Take
  a look at include/module.inc to investigate the details/changes.

- Improved design of the content modules "story", "book" and "node"
  (to aid smooth integration of permisions + moderate.module).  I'm
  still working on the permissions but I got side tracked for which
  I "Oops!".

- fixed issue depricated call-by-reference issues
- fixed small visual glitch in includes/function.inc
- changed SQL tables around a bit to be more consistent
  (result: small changes to a lot of different files)
- improved robustness of includes/node.inc
- improved output of cron.module
- improved output of node.php

- applied David Norman's patch to turn all <?'s into fully qualified
  <?php's.

- removed redundant spaces

- fixed 2 small bugs in account.php
- drastically improved administration section
- drastically revamped story administration:
  added new feature to schedule the publishing of stories
- applied correct naming conventions to submission.php
- fixed 1 small glitch in boxes
- somewhat expanded the documentation
= changed one SQL table
- updated the faq with info on drupal
- ... and more things I forgot about
