  FormAPI now offers the 'image_button' element type, allowing developers to
  use icons or other custom images in place of traditional HTML submit buttons.

  The $row argument of db_result() was removed from the database abstraction
  layer in 6.x core, as it was a database dependent option. Developers need to
  use other handling to replace the needs of this method. */

/* TODO New user_mail_tokens() method may be useful.
  user.module now provides a user_mail_tokens() function to return an array
  of the tokens available for the email notification messages it sends when
  accounts are created, activated, blocked, etc. Contributed modules that
  wish to make use of the same tokens for their own needs are encouraged
  to use this function. */

  There is a new hook_watchdog in core. This means that contributed modules
  can implement hook_watchdog to log Drupal events to custom destinations.
  Two core modules are included, dblog.module (formerly known as watchdog.module),

  included in the logging_alerts module. See syslog or emaillog for an
  example on how to implement hook_watchdog.
