    throwing in 5.0.0, we inadvertently removed the ability for callers to peek the trailers
    (by catching the `IllegalStateException` if they weren't available). This new API restores that
    capability.

 *  Fix: Don't crash on `trailers()` if the response doesn't have a body. We broke [Retrofit] users
    who read the trailers on the `raw()` OkHttp response, after its body was decoded.

### SIG Scalability

[SIG Scalability][] is responsible for scalability testing, measuring and
improving system performance, and answering questions related to scalability.

For the 1.8 release, SIG Scalability focused on automating large cluster
scalability testing in a continuous integration (CI) environment. The SIG
defined a concrete process for scalability testing, created

- Add metric etcd_lease_object_counts for kube-apiserver to observe max objects attached to a single etcd lease. ([#97480](https://github.com/kubernetes/kubernetes/pull/97480), [@lingsamuel](https://github.com/lingsamuel)) [SIG API Machinery, Instrumentation and Scalability]

- Reduce critical section in watchcache to fix kube-apiserver scalability under heavy load of list requests ([#122027](https://github.com/kubernetes/kubernetes/pull/122027), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

- CephRBD volume plugin ( `kubernetes.io/rbd`) was removed in this release. And its csi migration support was also removed, so the `rbd` volume type became non-functional. Alternative is to use RBD CSI driver (https:...
