#699858 by David_Rothstein, catch, yoroy, sun, ronald_istos, et al: Fix admin/by-task is confusing because it looks too similar to admin/config. Makes admin/by-task a very minimal view, and makes admin/by-module a more fully fledged index.

#620616 by Bojhan, reglogge, lisarex, jhodgdon, and yoroy: Fix inconsistencies in menu description labeling.

#679890 follow-up by Bojhan, aspilicious, and agentrickard: Remove more extraneous 'Please' in the interface.

- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.

#497118 by chx, catch, pwolanin, JoshuaRogers, and Jacob Singh: Remove the function registry. While the hope was that this would result in improved performance for low-end hosts, it comes at the expense of critical development experience problems and less benefit than something like APC. Class registry remains intact to facilitate autoloading.

Of all the patches to accidentally commit without a message. :( Rolling back registry rip. Let's try that again.

- Patch #536440 by Gábor Hojtsy: the attached patch moves the Structure >> Themes section to the top level Appearance item as outlined in the D7UX IA.

  et al.  Can you say 'registry'?  Drupal now maintains an internal registry of
  all functions or classes in the system, allowing it to lazy-load code files as
  needed (reducing the amount of code that must be parsed on each request). The
  list of included files is cached per menu callback for subsequent loading by
  the menu router. This way, a given page request will have all the code it needs
  but little else, minimizing time spent parsing unneeded code.

  Drupal core!  This is an important milestone for the project so enable
  the module and check it out ... :)

  Thanks to Rok Žlender, Károly Négyesi, Jimmy Berry, Kevin Bridges, Charlie
  Gordon, Douglas Hubler, Miglius Alaburda, Andy Kirkham, Dimitri13, Kieran
  Lal, Moshe Weitzman, and the many other people that helped with testing
  over the past years and that drove this home.

  It all works but it is still rough around the edges (i.e. documentation
  is still being written, the coding style is not 100% yet, a number of
  tests still fail) but we spent the entire weekend working on it in Paris
  and made a ton of progress.  The best way to help and to get up to speed,
  is to start writing and contributing some tests ... as well as fixing
  some of the failures.

  For those willing to help with improving the test framework, here are
  some next steps and issues to resolve:

    - How to best approach unit tests and mock functions?
    - How to test drupal_mail() and drupal_http_request()?
    - How to improve the admin UI so we have a nice progress bar?
    - How best to do code coverage?

- Patch #245115 by kkaefer, John Morahan, JohnAlbin et al: after a long discussion we've decided to make the concatenation operator consistent with the other operators.

#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

#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

- Patch #132018 by alienbrain: replace instances of _module_parse_info_file() with drupal_parse_info_file().

- Patch #34755 by chx et al: faster menu system.  HEAD is temporary broken and there is no upgrade path yet.

#100516: CSS preprocessor to cache and compress all .css files. Benchmarks show up to 40% faster page loads.

- Patch #92992 by webchick and neclimdul: clean up documentation that is superseded by the new 'by module' administration dashboard.
