# Juju 2.2-rc1 Release Notes We are delighted to announce the release of Juju and conjure-up 2.2-rc1! 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 https://jujucharms.com/docs/devel/reference-releases#development Please note that if you are upgrading an existing controller, please make sure there is at least 6G of free disk space. The upgrade step for the logs can take a while, in the vicinity of 10 or more minutes if the current logs collection is at its maximum size.
