# juju-core 1.23.1
A new proposed stable release of Juju, juju-core 1.23.1, is now available.
This release may replace version 1.23.0 on Thursday April 23.
## Getting Juju
juju-core 1.23.1 is available for vivid and backported to earlier
series in the following PPA:
https://launchpad.net/~juju/+archive/proposed
Windows and OS X users will find installers at:
https://launchpad.net/juju-core/+milestone/1.23.1
Proposed releases use the "proposed" simple-streams. You must configure
the `agent-stream` option in your environments.yaml to use the matching
juju agents.
## Notable Changes since 1.23.0
### Experimental: Addressable LXC Containers and KVM Instances on AWS and MAAS
The Juju AWS and MAAS providers now support starting LXC containers. The
MAAS providers also supports networking on KVM. Containers and Virtual
Machines will be given statically allocated private IP addresses from
the same subnet as their host machine. For example on MAAS you can now:
juju deploy wordpress --to lxc:0
juju add-unit mysql --to kvm:1
This experimental feature can be enabled when the environment is
bootstrapped like so:
JUJU_DEV_FEATURE_FLAGS="address-allocation" juju bootstrap
These two units can now talk directly on the private subnet.
## Resolved issues
* Addressable containers cannot resolve non-fqdn in maas
Lp 1445063
* Vivid bootstrap and destroy-environment intermittently fails
Lp 1446662
