We released a new version of Fabric recently, version 0.2.2. It is much faster and more robust than the previous release. It’s what we used for our NSDI 2014 paper on warranties as a performance comparison point. We also released the version of Fabric that has warranties in it. That’s still a bit less robust, so it’s separate.
