Today we're announcing etcd v3.1.0-rc.1, as part of etcd v3.1 release process.

Please try the alpha and report any bugs to help stabilize the v3.1 release.

Some highlights of what’s new in etcd 3.1:

V3 features:

  • gRPC smart proxy with watch coalescing and key caching
  • Authentication
  • Lease information lookup RPC
  • Automatic client endpoint synchronization to cluster

General server features:

  • Faster linearizable reads
  • Server gateway for static client endpoints
  • Automatic cluster leadership transfer on server shutdown
  • Membership health checking to prevent accidental quorum loss
  • Embeddable etcd server

Complete release notes for 3.1 will be bundled with the 3.1 general release.
