This setting will be removed in a future release, Go 1.22 at the earliest.

### Go 1.10

Go 1.10 changed how build caching worked and added test caching, along
with the [`gocacheverify`, `gocachehash`, and `gocachetest` settings](/cmd/go/#hdr-Build_and_test_caching).
There is no plan to remove these settings.

### Go 1.6

Go 1.6 introduced transparent support for HTTP/2,

* Webhook always retries connection reset error. ([#53947](https://github.com/kubernetes/kubernetes/pull/53947), [@crassirostris](https://github.com/crassirostris))
* Adjust batching audit webhook default parameters: increase queue size, batch size, and initial backoff. Add throttling to the batching audit webhook. Default rate limit is 10 QPS. ([#53417](https://github.com/kubernetes/kubernetes/pull/53417), [@crassirostris](https://github.com/crassirostris))

#### Caching

Config translation typically takes the overwhelming majority of Istiod's resource usage. In particular, protobuf encoding. As a result, caching has been introduced, storing the already encoded `protobuf.Any` for a given resource.

			printSpaces(initPrintNum+printLevel1), strings.Join(matchingSubsets, ","))
		if len(nonmatchingSubsets) > 0 {
			fmt.Fprintf(writer, "%s(Non-matching subsets %s)\n",

                     * happens, add on class-path or module-path if allowed, or keep patching otherwise.
