+## 1.13.1 (2017-02-06)
+
+**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:
+
+1. Remove plugins.json from: `/var/lib/docker/plugins/`.
+2. Restart Docker. Verify that the Docker daemon starts with no errors.
+3. Reinstall your plugins.
