juju-core 1.13.3

A new development release of Juju, juju-core 1.13.3, is now available.

Getting Juju

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

juju-core 1.13.3 is available from the Juju development PPA


New and Notable

 * The new command “juju unset <service> <setting1> …” allows a
configuration setting for a service to be removed. Removing the
configuration setting will revert it to the charm default. This is the
first step in solving #1194945.
 * The Windows Azure provider now defines a public storage container
for tools. No configuration changes are required. Closes #1216770.

Resolved issues

 * A bug relating to the formatting of tool versions has been
resolved. This formatting error was only visible when using the -v or
--debug flag. Closes #1216285.

Configuration changes

 * none

Known issues

 * The JUJU_ENV environment variable is not being passed down to
plugins. LP #1216254.
 * An unexpected dependency between the api server and the
provisioning worker (which runs the same process) can cause delays
provisioning new machines. LP #1220027.

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):


For HP Cloud the public bucket is available at:


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.
