Comment 12 for bug 1469744

I certify Juju 1.22.6 is compatible with trusty previous jujus and with the Juju ecosystem at large.

Ubuntu juju 1.22.6 on trusty is compatible with 1.22.x from upstream Juju. It is suitable deploying and maintaining environments in public and private clouds. Juju is compatible with the versions of quickstart (and deployer) provide by Ubuntu main. Upgrades from 1.18.4 and 1.20.11 work fine. The version is suitable for local testing and charm development.

This version addresses the aws, azure, and joyent degradations that trusty users have experienced as public clouds introduced new regions, AZs, and networks. For example. Deploying the landscape-scalable bundle will likely fail using 1.20.11 un AWS because of the high probability of getting an unsupported AZ. Juju 1.22.6 handle the situation.
