If the remote handler is blocked on a send, and the client is trying to send without the remote receiving,
the operation would become deadlocked if the channels are full.

### Typed handlers

Typed handlers are handlers that have a specific type for the request and response payloads.

```go
    // Create a typed handler.

	// - missing format.json (unformatted drive)
	// - format.json is valid but invalid 'uuid'
	if err = p.checkDiskStale(); err != nil {
		return ctx, done, err
	}

	// Disallow recursive tracking to avoid deadlocks.
	if ctx.Value(healthDiskCtxKey{}) != nil {
		done = p.updateStorageMetrics(s, paths...)
		return ctx, done, nil
	}

	if contextCanceled(ctx) {
		return ctx, done, ctx.Err()
	}

completely eliminate the IP allocation issue. More information [here](https://github.com/kubernetes/kubernetes/issues/21523#issuecomment-191498969)
  * Daemon becomes unresponsive (rarely) due to kernel deadlocks. More information [here](https://github.com/kubernetes/kubernetes/issues/21866#issuecomment-189492391)

### Provider-specific Notes

#### Various

   Core changes:

  * Change default clusterCIDRs from /16 to /14 allowing 1000 Node clusters by default.
  * Allow Debian Jessie on GCE.
  * Node problem detector addon pod detects and reports kernel deadlocks.
* OpenStack
  * Provider added.
* VSphere:
  * Provider updated.

release 3.5.0 and the community embraced it. The new release comes with improvements to the Security, performance, monitoring and developer experience. There are numerous bug fixes to lease objects causing memory leaks, and compact operation causing deadlocks and more. A couple of new features are also introduced like the migration to structured logging and build in log rotation. The release comes with a detailed future roadmap to implement a solution to traffic overload. A full and detailed list of changes...

### Fixes

* 🐛 Allow exit code for dependencies with `yield` to always execute, by removing capacity limiter for them, to e.g. allow closing DB connections without deadlocks. PR [#5122](https://github.com/tiangolo/fastapi/pull/5122) by [@adriangb](https://github.com/adriangb).
