Paul Thurrott has blogged about the release of Windows Live Writer 14 beta. You can find about WLW 14 through the link to his blog.
(the reason why it is 14 because Writer is a subset of the blogging functions of Word, and other Live software is at 12. Thus, this may be a preview of the blogging functions of Word 14! they also skipped 13 due do superstition)
