There's just one very small change in this release, that may fix a problem people are having with dates in noteblog-style blogs. I don't have a set of steps to create the problem on my system, that's why I'm not sure if this is the fix or not, but I did find a problem.
One thing that was clear from reviewing the CMS code, you won't get good results with stream types if you make the calendar entries by hand.
You should use the big gray plus icon at the top of the icon bar at the left of the window to create new blog entries. It automatically sets the attributes up the way the CMS is expecting them.
If you don't use the plus to create blog entries, you may see problems with dates. This may have been responsible for some of the problems we've been seeing.
