## v4.0.0 (TBD)
See [code changes](https://github.com/coreos/etcd/compare/v3.3.0...v4.0.0) and [v4.0 upgrade guide](https://github.com/coreos/etcd/blob/master/Documentation/upgrades/upgrade_4_0.md) for any breaking changes.
### Breaking Changes
- Deprecate [v2 storage backend](https://github.com/coreos/etcd/issues/9232).
- v2 API is still supported via [v2 emulation]().
- `clientv3.Client.KeepAlive(ctx context.Context, id LeaseID) (<-chan *LeaseKeepAliveResponse, error)` is now [`clientv4.Client.KeepAlive(ctx context.Context, id LeaseID) <-chan *LeaseKeepAliveResponse`](TODO).
- Similar to `Watch`, [`KeepAlive` does not return errors](https://github.com/coreos/etcd/issues/7488).
- If there's an unknown server error, kill all open channels and create a new stream on the next `KeepAlive` call.
