We are very happy to announce the release of Habitat 0.23.0. As usual, we have a number of new features as well as bug fixes, so please read on for all the details. If you just want the binaries, head on over to our downloads page: [https://www.habitat.sh/docs/get-habitat/](https://www.habitat.sh/docs/get-habitat/) Thanks again for using Habitat!

## Breaking Change: 0.23.0 Supervisors cannot communicate with earlier versions

As of today’s release, supervisors will be communicating system information (SysInfo) using protobuf. This change is necessary in order to allow multi-service supervisors to reliably gossip with one another. [#2314]

Please note: you will need to delete `/hab/sup/default/data` when you upgrade.

([https://github.com/habitat-sh/habitat/pull/2314](https://github.com/habitat-sh/habitat/pull/2314))

## Support optional package bind validation

Optional package binds are now properly validated on service loading in the Supervisor. Any package bind provided that is not a required or an optional bind will correctly cause an error. [#2294](https://github.com/habitat-sh/habitat/pull/2294) [#2284](https://github.com/habitat-sh/habitat/pull/2284)

## Add configurable update frequency

Based on popular demand, users can now have their supervisors check for updates more frequently if their workflow requires it. [#2316](https://github.com/habitat-sh/habitat/issues/2316)

This also adds better debug messaging when update workers die. The messages emitted when an update worker dies may raise a red flag in the mind of an observer when none is warranted. A dying update worker is a healthy milestone of the updater lifecycle. This is now a debug message to protect those sensitive to death. This also clearly states the old and new release versions. [#2320](https://github.com/habitat-sh/habitat/pull/2320)
