In v0.9, changes will be made to the command line options to improve usability. These will be breaking changes; that is,
in many cases the v0.8 command line options will no longer work. The
[Pantheon documentation](https://docs.pantheon.pegasys.tech/en/latest/Reference/Pantheon-CLI-Syntax/) will be
updated to reflect these changes. Any further information required about the changes will be included in the v0.9 release notes.
### Private Network Quickstart
In v0.9, the Private Network Quickstart will be moved to a separate repository and the existing Private Network
Quickstart removed from the Pantheon repository. The [Private Network Quickstart tutorial](https://docs.pantheon.pegasys.tech/en/latest/Getting-Started/Private-Network-Quickstart/)
will be updated and use the Private Network Quickstart in the separate repository.
## 0.8.4
### Docker Image
If you have been running a node using the v0.8.3 Docker image, the node was not saving data to the
or referring to the custom [configuration file](https://docs.pantheon.pegasys.tech/en/latest/Getting-Started/Run-Docker-Image/#custom-configuration-file)
or [genesis file](https://docs.pantheon.pegasys.tech/en/latest/Getting-Started/Run-Docker-Image/#custom-genesis-file).
To recover the node key and data directory from the Docker container:
Where `container` is the name or ID of the Docker container containing the Pantheon node.
The container can be running or stopped when you copy the key and data directory. If your node was
fully synchronized to MainNet, the data directory will be ~2TB.
When restarting your node with the v0.8.4 Docker image:
* Save the node key in the [`key` file](https://docs.pantheon.pegasys.tech/en/latest/Configuring-Pantheon/Node-Keys/#node-private-key) in the data
directory or specify the location using the [`--node-private-key` option](https://docs.pantheon.pegasys.tech/en/latest/Configuring-Pantheon/Node-Keys/#specifying-a-custom-node-private-key-file).
* Specify the `<destination_directory` as a [volume for the data directory](https://docs.pantheon.pegasys.tech/en/latest/Getting-Started/Run-Docker-Image/#data-directory).
