In trying to find a way to notify developers of D7 API changes, the best
solution we've come up with is to formally publish to the Drupal Development
Mailing List. API change notifications will occasionally be posted here with
a title starting with "Drupal 7 API Change notification"

These two API changes were recently committed to Drupal 7:

   1. *hook_block_info_alter() has been renamed to
   *. If your D7 module was using hook_block_info_alter() it will need to be
   updated. Issue: #560746: Rename hook_block_info_alter() to
   hook_block_list_alter() and add
   See block_example.module<http://api.drupal.org/api/function/block_example_block_list_alter/7>for
sample usage.|

   2. *Content types no longer have a body field unless one is explicitly
   added*. This means that:
      - If your content type requires a body field, you must call
      node_add_body_field() in hook_install(). Example in

      - the has_body and has_body_label attributes no longer do anything
      - In at least one
      a Drupal core reinstall was required.

   Issue: #553306: Make nodes have no body field by default. Remove
   deprecated APIs for body field <http://drupal.org/node/553306>
