Today we released etcd 0.2.0 which introduces major features including an improved v2 API, two new modules for fair locking and leader election, and tons of new features.

Major Changes

v2 API

etcd 0.2.0 introduces a new API endpoint at /v2. This API has been built on all of the feedback we have gotten from the community of users who have been building projects on etcd. The major features of the new API include:

Update: This blog post refers to functionality in an older version of etcd, 0.4.x. Check out the updated Docker guide for up-to-date information.

Just a few updates on the CoreOS alpha for you. The latest release (160.0.1) includes:

CoreOS is designed to deliver high-density compute resources. The best way to take advantage of this concept on a small scale is run a personal utility cluster (or single machine) to run various utilities like IRC bouncers and the handful of websites that you inevitably end up hosting. CoreOS is a small, efficient operating system, which means you get more bang for your buck even on small cloud instances.

CoreOS can now be run on Google Compute Engine! We're working hard to support all of the awesome unique features of GCE, but for now CoreOS functions the same as our other supported platforms.

This etcd release, v0.1.2, is putting some final polish on the 0.1 series of releases. The big feature is a new dashboard designed to visualize the latency of the followers in the network and give you the ability to browse and edit the keyspace. Checkout this Youtube video for details.

There have been a lot of requests from all of you about running CoreOS on physical gear. You want to use all of the features of CoreOS like atomic system upgrades, distributed configuration and Docker containers with the increased speed, flexibility and simplicity of bare metal. It makes a lot of sense to us too and we have been working to get the pieces in place for you to get CoreOS on your bare metal.

We just uploaded images for OpenStack, VMware and KVM to make it easy for more of you to be involved in the CoreOS developer alpha. These images come fresh from our build system and we would love your feedback on what is working and what isn't.

etcd is ready for its first release! We just marked v0.1.0 and uploaded binaries for Linux and OSX.

These are the major features in this release:

Our first vagrant images are ready to try. If you are new to vagrant checkout our Vagrant guide for install instructions. Already have vagrant? Then it is as simple as:

git clone
cd coreos-vagrant
vagrant up
vagrant ssh

Thanks to @mitchellh (vagrant creator) for helping us get this going.
