- Patch #15500 by Morbus: ignore unpublished comments when determining last_post.  (This matches the behavior in HEAD.)

- Patch #15337 by Gerhard: fixed bug in upgrade path.  The 'update_start' variable got corrupted.

- Patch #15399 by adschar: fixed PHP5 error when a new session is inserted into the session table.

- Patch #11366 by Junyor: fixed problem with comment counts.

- Patch #14710 by tangent: only show post button if preview is optional or if we are in preview mode.  We show the post button in preview mode even if there are form errors so that optional form elements (e.g., captcha) can be updated in preview mode.

- Patch #14334 by killes: fixed PHP warning.

- Patch #14288 by Goba: "the archive module calendar indexes the array used to build up the header cells by the short names of the days. In Hungary, we have both Wednesday and Sunday start with the same two letters, so if I translate the short versions with the same two letters, the second associative array index will overwrite the first. The obvious soluion was to swap the array, and index by the full day name, which is expected to be unique in all languages."

   * user/view/$n has been replaced with user/$n.
   * More blank lines in the right places.
   * Prevent unwanted case fallthrough.

- Added a note about PHP5 compatibility to avoid future confusion.  DRUPAL-4-5 only.

- Patch #13405 by Moshe: make you actually do something useful with the init hook.  A recent patch to 4.5 and HEAD made this patch run too early in the request (for non-cached pages).

- Modified patch #6475 by Killes: sites -> drupalsites -> drupal-sites.
