- Patch #252013 by Eaton, pwolanin, Susurrus et al: drupal_render() now printes #markup, not #value.

  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.

- 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.

- 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.
