• Add ETCD_HTTP_READ_TIMEOUT and ETCD_HTTP_WRITE_TIMEOUT (#880)
• Add ETCDCTL_PEERS configuration to etcdctl (coreos/etcdctl#95)
• etcdctl takes stdin for mk (coreos/etcdctl#91)

v0.4.4

Minor bugfix release for etcdctl, logging and documentation.

• Fix --no-sync flag in etcdctl (#83)
• Improved logging for machine removal (#844)
• Various documentation improvements (#858, #851, #847)

v0.4.3

• Avoid panic() on truncated or unexpected log data (#834, #833)
• Fix missing stats field (#807)
• Lengthen default peer removal delay to 30mins (#835)
• Reduce logging on heartbeat timeouts (#836)

• 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
