- Patch #216072 by recidive, David Rothstein, ptalindstrom et al: switched from numeric block IDs to string IDs.

  The short explanation is that Drupal uses a lot of numeric deltas in the block system; blocks are identified by the 'module' and the 'delta'. In early Drupal, delta was numeric, but somewhere along the line it was changed to be possibly a string. In modern Drupal, block overrides are easily done via block-MODULE-DELTA.tpl.php.  The primary motivation to switch to string IDs everywhere is to make these deltas friendlier to themers:

    block-user-0.tpl.php --> block-user-navigation.tpl.php
    block-user-1.tpl.php --> block-user-login.tpl.php

  You get the picture.

- Patch #30984 by webchick, keith.smith, kkaefer, Crell et al: provide descriptions for permissions on the permission administration page.

#153998 by David_Rothstein and myself: clean up permissions in book, blog, blogapi, forum and locale modules

#203582 by David_Rothstein: some core hook_access() implementations are not using the passed in account

#67895 patch by myself, tested by JirkaRybka and blackdog: move poll votes with poll options, when an option is removed, instead of dropping all old votes, solving an old data loss bug

#200069 by keith.smith: new standard for 'more information' links in module help texts, as the handbook we referred to before was renamed

#197297 by DanW (as GHOP 17), and keith.smith: clean up lots of help texts, update to drag and drop functionality, drupal.module removal, etc

 - whitespaces at end of lines
 - indentation
 - control structure usage
 - whitespace in empty lines
 - phpdoc comment formatting

#189009 by AjK: edit own poll permission was missing from poll module (although available for other content types)

#184198 by Eaton: move button title change in polls to the theme, so it does not interfere with the cached form

#184867 by deekayen, catch and keith.smith: fix some spelling errors in our source code and messages printed

#72487 by chx, pwolanin and moshe weitzman: let node_access() work on arbitrary users, so independent user access checks can be done in a request

- Patch #168028 by dvessler, merlinofchaos, pwolanin et al: both theme functions and templates may need include files. Flush your caches.

#111127 by chx: cache node_load(), so heavy operations loading data from external sources and only invoked once (note that you should do everything dynamic in the view op, not the load op)

#110511 by bjaspan: poll listing page should have a 'count_sql' because the original query uses group by, so it is not countable properly

  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
