**Concurrency** and **parallelism** both relate to "different things happening more or less at the same time".

But the details between *concurrency* and *parallelism* are quite different.

To see the difference, imagine the following story about burgers:

### Concurrent Burgers { #concurrent-burgers }

	// Callbacks with results:
	// If set to nil, it will not be called.

	// agreed is called if all disks agreed.
	agreed func(entry metaCacheEntry)

	// partial will be called when there is disagreement between disks.
	// if disk did not return any result, but also haven't errored
	// the entry will be empty and errs will
	partial func(entries metaCacheEntries, errs []error)

    * If you are not switching kube-proxy between different modes, this change should not require any action.
    * This fixes a bug where restarting the iptables proxier can cause connections to fail (https://github.com/kubernetes/kubernetes/issues/75360).

 *  New: Enforce label length limits in URLs. `HttpUrl` now rejects URLs whose domains aren't valid.
    This includes overly-long domain names (longer than 253 characters), overly-long labels (more
    than 63 characters between dots), and empty labels.
 *  New: Don't include the `Content-Length` header in multipart bodies. Servers must delimit
    OkHttp's request bodies using the boundary only. (This change makes OkHttp more consistent with
