Two Unwakeable releases within a month is a record. Anyway, Unwakeable 1.5.6 is available for download.
Unwakeable was again denied for inclusion in the WordPress Themes Directory. All the issues you see listed on that trac ticket have been fixed. I have yet to submit Unwakeable 1.5.6 to the themes directory.
The biggest change in 1.5.6 is the inclusion of comment_form. The WordPress Themes Directory requires use of comment_form. K2 had a custom form in place for comments, so I removed that form and replaced it with the comment_form function. Changes other than that were pretty negligible (ie: replacing blog_info(‘url’) with ‘echo home_url()’).
You can see Unwakeable 1.5.6 in action here.
