Release notes [1][2][3]:
> ### 1.13.0 (2017-01-18) ###
>
> **IMPORTANT**: In Docker 1.13, the managed plugin api changed, as
> compared to the experimental version introduced in Docker 1.12. You
> must **uninstall** plugins which you installed with Docker 1.12
> *before* upgrading to Docker 1.13. You can uninstall plugins using the
> `docker plugin rm` command.
>
> If you have already upgraded to Docker 1.13 without uninstalling
> previously-installed plugins, you may see this message when the Docker
> daemon starts:
>
> ```
> Error starting daemon: json: cannot unmarshal string into Go value of
> type types.PluginEnv
> ```
>
> To manually remove all plugins and resolve this problem, take the
> following steps:
>
> * Remove plugins.json from: `/var/lib/docker/plugins/`.
> * Restart Docker. Verify that the Docker daemon starts with no errors.
> * Reinstall your plugins.
>
> […]
> ### 1.13.1 (2017-02-08) ###
>
> **IMPORTANT**: On Linux distributions where `devicemapper` was the
> default storage driver, the `overlay2`, or `overlay` is now used by
> default (if the kernel supports it). To use devicemapper, you can
> manually configure the storage driver to use through the
> `--storage-driver` daemon option, or by setting "storage-driver" in
> the `daemon.json` configuration file.
>
> […]
> ### v17.03.0-ce (2017-03-01) ###
>
> **IMPORTANT**: Starting with this release, Docker is on a monthly
> release cycle and uses a new YY.MM versioning scheme to reflect this.
> Two channels are available: monthly and quarterly. Any given monthly
> release will only receive security and bugfixes until the next monthly
> release is available. Quarterly releases receive security and bugfixes
> for 4 months after initial release. This release includes bugfixes for
> 1.13.1 but there are no major feature additions and the API version
> stays the same. Upgrading from Docker 1.13.1 to 17.03.0 is expected
> to be simple and low-risk.
