Breaking change wishlists.

v4.0.0 (TBD)

See code changes and v4.0 upgrade guide for any breaking changes.

Secure etcd by default?
Change /health endpoint output.
- Previously, {"health":"true"}.
- Now, {"health":true}.
- Breaks Kubernetes kubectl get componentstatuses command.
Deprecate etcd --proxy* flags; no more v2 proxy.
Deprecate v2 storage backend; no more v2 store.
- v2 API is still supported via v2 emulation.
Deprecate etcdctl backup command.
clientv3.Client.KeepAlive(ctx context.Context, id LeaseID) (<-chan *LeaseKeepAliveResponse, error) is now clientv4.Client.KeepAlive(ctx context.Context, id LeaseID) <-chan *LeaseKeepAliveResponse.
- Similar to Watch, KeepAlive does not return errors.
- If there's an unknown server error, kill all open channels and create a new stream on the next KeepAlive call.
Rename github.com/coreos/client to github.com/coreos/clientv2.
