- Make etcd server return `raft.ErrProposalDropped` on internal Raft proposal drop in [v3 applier](https://github.com/coreos/etcd/pull/9549) and [v2 applier](https://github.com/coreos/etcd/pull/9558).
- e.g. a node is removed from cluster, or [`raftpb.MsgProp` arrives at current leader while there is an ongoing leadership transfer](https://github.com/coreos/etcd/issues/8975).

- Improve [functional tester](https://github.com/coreos/etcd/tree/master/functional) coverage: [proxy layer to run network fault tests in CI](https://github.com/coreos/etcd/pull/9081), [TLS is enabled both for server and client](https://github.com/coreos/etcd/pull/9534), [liveness mode](https://github.com/coreos/etcd/issues/9230), [shuffle test sequence](https://github.com/coreos/etcd/issues/9381), [membership reconfiguration failure cases](https://github.com/coreos/etcd/pull/9564), [disastrous quorum loss and snapshot recover from a seed member](https://github.com/coreos/etcd/pull/9565), [embedded etcd](https://github.com/coreos/etcd/pull/9572).

- Remove [`pkg/cors` package](https://github.com/coreos/etcd/pull/9490).
- Change [`--experimental-enable-v2v3`](TODO) flag to `--enable-v2v3`; v2 storage emulation is now stable.
- Move internal package `"github.com/coreos/etcd/snap"` to [`"github.com/coreos/etcd/raftsnap"`](https://github.com/coreos/etcd/pull/9211).
- Move internal package `"github.com/coreos/etcd/etcdserver/auth"` to `"github.com/coreos/etcd/etcdserver/api/v2auth"`.

### API
- Add [`snapshot`](https://github.com/coreos/etcd/pull/9118) package for snapshot restore/save operations (see [`godoc.org/github.com/etcd/snapshot`](https://godoc.org/github.com/coreos/etcd/snapshot) for more).

- Add [`watch_id` field to `etcdserverpb.WatchCreateRequest`](https://github.com/coreos/etcd/pull/9065) to allow user-provided watch ID to `mvcc`.
- Corresponding `watch_id` is returned via `etcdserverpb.WatchResponse`, if any.
- Add [`fragment` field to `etcdserverpb.WatchCreateRequest`](https://github.com/coreos/etcd/pull/9291) to request etcd server to [split watch events](https://github.com/coreos/etcd/issues/9294) when the total size of events exceeds `--max-request-bytes` flag value plus gRPC-overhead 512 bytes.
