Downgrade from beta16

I just upgraded to beta16 and now I get the following error client is newer than server (client API version: 1.24, server API version: 1.23). Is it possible to downgrade back to beta15?

I just discovered a way around this. It is a documented feature of the docker-client

I simply set the API version to 1.23 using export DOCKER_API_VERSION=1.23
