   - **go.etcd.io/etcd/client/v3** - client library used to contact etcd over
   the network (grpc). Recommended for all new usage of etcd.
 
-  - **go.etcd.io/etcd/client/v2** - legacy client library used to contact etcd
-  over HTTP protocol. Deprecated. All new usage should depend on /v3 library.
-
   - **go.etcd.io/raft/v3** - implementation of distributed consensus
   protocol. Should have no etcd specific code. Hosted in a separate repository:
   https://github.com/etcd-io/raft.
