[ANN] juju-core 1.13.1 has been released

[David Cheney]

juju-core 1.13.1
================

A new development release of Juju, juju-core 1.13.1, is now available.

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

The location of the PPA has changed, please note the new location.

juju-core 1.13.1 is available from the Juju development PPA

https://launchpad.net/~juju/+archive/devel

New and Notable
---------------

 * The debug-hooks subcommand is now implemented. Closed issue #1027876.
 * The status subcommand now accepts service/unit filters, to limit
output; see “juju help status” for more information. Partially
addresses issue #1121916.
 * The juju cli command now returns a better error message when run
against an environment that has not been bootstrapped. Closes issue
#1028053.

Resolved issues
---------------

 * The juju-metadata plugin was excluded in error from the 1.13.0
release. This has been corrected.
 * The destroy-environment subcommand now requests confirmation before
running, with an option to quietly proceed (-y/--yes). Closed issue
#1121914.
 * The cost calculation for the openstack provider was updated to bias
towards the lowest number of CPU cores when choosing a machine type
matching the provided instance constraints. This closes issue
#1210086.

Configuration changes
---------------------

 * None

Testing on Canonistack and HP Cloud
-----------------------------------

A publicly readable bucket has been created for holding the Juju tools
on Canonistack. To use it, put this in your ~/.juju/environments.yaml
(all on one line):

        public-bucket-url:
https://swift.canonistack.canonical.com/v1/AUTH_526ad877f3e3464589dc1145dfeaac60

For HP Cloud the public bucket is available at:

        public-bucket-url:
https://region-a.geo-1.objects.hpcloudsvc.com/v1/60502529753910


As an unstable release we do not make guarantees about clean upgrade
paths of running environments from one 1.13.x version to another.
However, live-upgrades should work now, and will be a supported
feature of stable releases.

We encourage everyone to subscribe the mailing list at
juju-dev at lists.canonical.com, or join us on #juju-dev on freenode.
