- Patch #15948 by matteo: the book module should call the nodeapi hook when printing printer-friendly pages.

- Patch #14936 by Junyor: the 'add comment link' was not available for polls.

- Patch #15690 by Goba: the vocabulary node types checks in taxonomy.module are very vulnerable to having node types names as prefixes of other node type names %%%s%% as it is there with %%blog%% will match a lot more, then just this simple node type.  Since the node types are stored in a comma separated list, the solution is to search for 'blog' or '%%,blog,%%' or 'blog,%%' or '%%,blog', that is matching only for that node type, or matching that node type in a list, or at the beginning of a list, or at the end of a list. It does not look elegant, but this is the solution for the format used.

- Patch #15500 by Morbus: ignore unpublished comments when determining last_post.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

- 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 #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.

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

   1. Fixed broken watchdog calls: two watchdog calls omitted the type parameter, and thus injected logs into the type field, instead of the message field.
   2. Removed t() functions from user contributed content.

- Patch #12555 by svemir: fixed problem with the 'Preview comment' button not being present when previews are optional.

- Patch #11977 by matteo: added extra DISTINCT()s to two SQL queries to make them work with node-level permissions.

- Bug 13503: updating the locale settings might impact the interface (eg. menu's) so we have to flush the cache.

- Patch #11977 by matteo: taxonomy_term_count() did not take node-level permissions into account and could return an incorrect number.

- Patch #11940 by kps: if the user is not allowed to view a newly submitted node, redirect him to the main page.

- Patch #12658 by menesis: when an administrator adds a user, the 'authenticated user' role was not assigned to the new user.

- Patch #11871 by killes: forum topics could be displayed multiple times when node-level permission were used.
