> New and Notable
> ---------------
> 
> This release includes several improvements
> 
> * juju-core now respects the default-series configuration key to control 
> the release series of the target environment.
> * juju-core now supports all EC2 regions. Please raise a bug on the 
> juju-core project if you experience an issue using juju-core with the 
> EC2 provider.
> 
> Known bugs and limitations
> --------------------------
> 
> As this is an early release of Juju in Go there are a number of features 
> which are still to be implemented. A non exhaustive list of known issues 
> is as follows.
> 
> * EC2 is the only supported provider.
> * Raring series environments are not supported.
> Most types of relations are supported, but they are not displayed in 
> juju status. #1073966
> * The ssl-hostname-verification configuration key is not valid in an 
> environments.yaml configuration. The EC2 provider does perform ssl host 
> verification by virtue of only talking to https endpoints. As a 
> temporary measure, please remove this key from your environments.yaml. 
> #1074025

FYI, the point of this key is not to turn it on. It should ALWAYS
default to on, and was only defaulted to off for one release to not
break backward compatibility.

The point is to be able to turn it off for private cloud/testing/etc.
