Subject Re: Upgrade from 0.8 trunk to 0.8 GA?
Date Mon, 10 Dec 2012 07:24:55 GMT
That being said, does it make sense to release a 0.7.3?  Since there are
some fixes post 0.7.2, which are not 0.8 related.  Currently, I am using
trunk, cuz a few things are fixed with shutting down gracefully after no
activity, etc....
