I have just upgraded to Docker 1.10, which is what this site runs under and it seems to have gone well.
Watch this video overview on the new features in version 1.10:
The commands were simple to upgrade the engine to version 1.10 from my Ubuntu box
sudo apt-get update
sudo apt-get upgrade docker-engine
Then after a slight pause my containers were live again and I confirmed the upgrade worked

curl -L https://github.com/docker/compose/releases/download/1.6.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
Then to check the upgrade succeeded
I hope to explore some of the new features in the coming weeks but it's well worth upgrading today. I'll see if there any gotchas but as far as the upgrade has gone, it been plain sailing so far.
