v0.2.0-rc3

This release sees a variety of bug fixes and new features that should get us close to a final 0.2.0 release. There have also been a few minor adjustments to the v2 API in this release to solve problems people were seeing.

etcd

• New leader election module (see https://github.com/coreos/etcd#leader-election)
• Documentation added for the lock module (see https://github.com/coreos/etcd#lock)
• Flags added to adjust heartbeat and election timeouts
• Remove the PrevValue field from the Node object (see http://thread.gmane.org/gmane.comp.distributed.etcd/56)
• Add a dir parameter for explicitly creating, updating and deleting directories (see #349)
• Dashboard module had a variety of bug fixes
• Added directory TTL API documentation

etcdctl

• etcdctl --debug dumps the cluster peers to ease debugging
• etcdctl ls --recursive prints out the key space recursively now
• etcdctl --peers is parsed identically to the etcd flag

Getting Started

To get started on OSX run the following in a terminal:

curl -L  https://github.com/coreos/etcd/releases/download/v0.2.0-rc3/etcd-v0.2.0-rc3-Darwin-x86_64.tar.gz -o etcd-v0.2.0-rc3-Darwin-x86_64.tar.gz
tar xzvf etcd-v0.2.0-rc3-Darwin-x86_64.tar.gz
