How to test

Installing pre-released versions of Juju
You can take a sneak peek at the features being released:
Juju 2.8 series brings several features to the Juju community.
Improved resource usage
Juju agents (jujud processes) now use less memory, particularly for long-lived models.
Several internal changes have led to speed improvements while executing hooks. This means that all Juju operations should run faster on Juju 2.8 than previous versions.

Feature Development Easier selection of custom image metadata
From 2.8, it will now be much easier to supply custom virutal machine image ncluding for non-Ubuntu operating systems such as CentOS and openSUSE. The details have been provided in a seperate post.
Juju 2.8 will make it much easier to configure Juju to use centos and windows images on clouds like AWS or Openstack which use simplstreams metadata to catalog the available images. This feature will be in 2.8-rc1 or the 2.8-rc1+develop-8c74d2a53a edge snap before that.
There’s 3 basic commands:
juju metadata add-image
juju metadata delete-image
juju metadata list-images
In its simplest form, add-image is used to register an image id for a specified series. Other attributes from s…
Backup and restore
juju-restore tool moved to its 0.9 release. It allows you to restore to a previous release of Juju, in case a future version triggered an issue with your model.
Hi everyone -
new release of juju-restore available. This adds autoloading the credentials from the machine agent config on the current controller node, so you don’t have to do that yourself. It also fixes a bug that miscounted HA nodes in backup files.
The main change though is that juju-restore now supports restoring a backup that was taken from an earlier Juju version if the --allow-downgrade option is passed. This means that if you take a backup before upgrading the controller, a…
New Actions workflow, enable with JUJU_FEATURES environment variable
Juju 2.8 introduces a new evironment variable:
JUJU_FEATURES. It is intended for selectively enabling features that are expected to be introduced as defaults in Juju 3.0. The first feature to make use of
JUJU_FEATURES is the new actions workflow.
The UX around Juju Actions has undergone a fairly radical re-design to address some long standing issues and deliver some nice usability improvements.
An early version of this was delivered in Juju 2.7. Coming in Juju 2.8 is a more polished iteration.
running an action defaults to synchronous (block until done)
running actions can be cancelled
new ability to display progress log messages
cleaner plain text output option
stdout and stderr included in output
