I found another HTML typo, and replaced a <u></u> by <strong></strong> because <u> does not validate as 'XHTML 1.0 stict'.

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

- Patch #15976 by Neil: if one single admin modifiable menu item is added then it is not put in the menu table because the comparison is > 1 instead of > 0.

- 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- Patch #15500 by Morbus: ignore unpublished comments when determining last_post.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 #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."
