## Nomad 0.12.0
### Enterprise Licensing
Enterprise binaries for Nomad are now publicly available via
[releases.hashicorp.com](https://releases.hashicorp.com/nomad/). By default all
enterprise features are enabled for 6 hours. During that time enterprise users
should apply their license with the [`nomad license put
...`](https://www.nomadproject.io/docs/commands/license/put) command.
Once the 6 hour demonstration period expires, Nomad will shutdown. If restarted
Nomad will shutdown in a very short amount of time unless a valid license is
applied.
~> **Warning:** Due to a [bug][gh-8457] in Nomad v0.12.0, existing clusters
that are upgraded will **not** have 6 hours to apply a license. The minimal
grace period should be sufficient to apply a valid license, but enterprise
users are encouraged to delay upgrading until Nomad v0.12.1 is released and
fixes the issue.
### Docker access host filesystem
Nomad 0.12.0 disables Docker tasks access to the host filesystem, by default.
