# Juju 2.2-beta4 Release Notes

We are delighted to announce the release of Juju and conjure-up 2.2-beta4!
In this release, Juju greatly improves memory and storage consumption,
works on KVM containers, and improves network modelling. conjure-up now
supports Juju as a Service (JAAS), provides a MacOS client, and adds
support for repeatable spell deployments.

The best way to get your hands on this release of Juju and conjure-up is to
install them via snap packages (see https://snapcraft.io/ for more info on
snaps).

        snap install juju --classic --beta

        snap install conjure-up --classic --beta

Other packages are available for a variety of platforms. Please see the
online documentation at

## New and Improved

------------------------------


* SSH Keys of the bootstrap host are now verified before bootstrap,
eliminating the opportunity for a MITM attack (lp:1579593).

* Actions on a unit can now be canceled (lp:1588092)

* OpenStack provider usability improvements:

* added support for neutron networks where port security is disabled
(lp:1680787).

* error handling when an instance fails to boot with “No valid host”
failure.

* experimental Oracle Compute provider

See https://jujucharms.com/docs/devel/help-oracle

Usability improvements:

* instance ids in Juju status are now user friendly.

Known limitations for this beta:

* destroy-controller might show an error if instance deletion takes too
long.

* yakkety bootstrap / workloads not supported.

* Juju’s agent presence data is now aggressively pruned, reducing
controller disk space usage and avoiding some performance issues.

* conjure-up now supports vsphere.


## Fixes

------------------------------


* Resolved json unmarshal errors while bootstrapping with the OpenStack
Provider (lp:1683495).

* MAAS 2.x block storage now works with physical disks, when MAAS reports
the WWN unique identifier. Previously, the storage would remain pending
(lp:1677001).

* Resolved issues with long bridge names (lp:1672327)
