Jon Carstens covered some of the work during his NervesConf talk as a well.

After the 2.x changes were available Josh Kalderimis joined in and started looking at ease of use which led to a lot of various improvements but the biggest one is the alternative device authentication method: Shared Secret

Since then we have contributions from 19 people where Eric Oestrich dominates the stats. Followed by Josh Kalderimis. Then Jon Carstens.

There are a lot of things planned. SmartRent, NervesCloud and other users of the project are in active collaboration on improving the featureset, the performance and the user experience. We want this to be not just a great tool for developers that choose Nerves but a surprising delight and joy to use.

Migration

You should be able to migrate using the Ecto migrations. Nothing should be break if you migrate a 1.x install to the 2.x releases. We still recommend that you set aside time for dealing with anything unusual that might come up.

You may also need some time to deprovision the AWS resources you no longer need.
