And, there may be bugs.<br /><br />One option would be to shorten the release cycle to get this out in an official release sooner. But then that means less will get into the release.Robert Haashttps://www.blogger.com/profile/08393677427643988650noreply@blogger.comtag:blogger.com,1999:blog-20038672.post-60324458591645602722011-07-22T03:32:56.447-04:002011-07-22T03:32:56.447-04:00Very goog news.
