[David Cheney]

juju-core 1.9.4
===============

A new experimental release of Juju, juju-core 1.9.4, is now available 
for testing. This is an early release of the Go port of Juju and should 
be considered experimental.

Getting Juju
------------

juju-core 1.9.4 is available from the Gophers PPA

https://code.launchpad.net/~gophers/+archive/go

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
* The juju-core package currently cannot be installed in parallel with 
juju 0.5/0.6 due to conflicting ownership of /usr/bin/juju (and others). 
This may be mitigated in the future with alternatives.
destroy-service is not yet implemented. As a workaround you can remove 
all the units assigned to a service. This is issue #1027878.
* terminate-machine is not yet implemented. #1073976
* Constraints are not yet implemented. #1027873
* Subordinate charms are not yet implemented.
