#100641 by kkaefer, ChrisKennedy and RobRoy: change 'Submit' buttons to 'Save' to compliy with the desktop metaphor and actually tell what the button does ('we know it submits the form, but what it does?')

#82499 by Jose A Reyero and a little bit from myself: send emails localized in the language needed in specific situations, and centralize mail composing operations with hook_mail()

  unanimously agreed to rollback the deletion API.  We all support the
  features this patch added, yet not its actual design and implementation.
  After some talk, we decided that it would be better for Drupal -- in the
  long term -- not to go with a solution that isn't 100%. We also recognize
  that in the short term, this patch would have been useful addition. So
  let's figure out how we can implement this properly in D7.

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

  This is a very important patch, but one that is merely an enabler.
  Hopefully we'll see more people submitting "action patches" in the
  near future.

  Thanks for the hard work and persistence, John.  *If* you decide
  to update the Drupal Pro Development book to Drupal 6, make sure
  to add a chapter on actions. ;)
