- Add [`--socket-reuse-address`](https://github.com/etcd-io/etcd/pull/12702) flag
- Setting this flag enables `SO_REUSEADDR` which allows binding to an address in `TIME_WAIT` state, improving etcd restart time.
- Reduce [around 30% memory allocation by logging range response size without marshal](https://github.com/etcd-io/etcd/pull/12871).
+- `ETCD_VERIFY="all"` enviroment triggers [additional verification of consistency](https://github.com/etcd-io/etcd/pull/) of etcd data-dir files.
### Package `runtime`
- Optimize [`runtime.FDUsage` by removing unnecessary sorting](https://github.com/etcd-io/etcd/pull/12214).
