- Added a feature to report an event about a Pod if kubelet observes a failed attach operation, even if the kubelet is running with `--enable-controller-attach-detach=false`. ([#124884](https://github.com/kubernetes/kubernetes/pull/124884), [@carlory](https://github.com/carlory))

- For volumes that allow attaches across multiple nodes, attach and detach operations across different nodes are now executed in parallel. ([#89240](https://github.com/kubernetes/kubernetes/pull/89240), [@verult](https://github.com/verult)) [SIG Apps, Node and Storage]

This combination of Flask, Flask-apispec with Marshmallow and Webargs was my favorite backend stack until building **FastAPI**.

Using it led to the creation of several Flask full-stack generators. These are the main stacks I (and several external teams) have been using up to now:

* <a href="https://github.com/tiangolo/full-stack" class="external-link" target="_blank">https://github.com/tiangolo/full-stack</a>

			HandlerFunc(adminMiddleware(adminAPI.SetPolicyForUserOrGroup)).
			Queries("policyName", "{policyName:.*}", "userOrGroup", "{userOrGroup:.*}", "isGroup", "{isGroup:true|false}")

		// Attach/Detach policies to/from user or group
		adminRouter.Methods(http.MethodPost).Path(adminVersion + "/idp/builtin/policy/{operation}").HandlerFunc(adminMiddleware(adminAPI.AttachDetachPolicyBuiltin))

		// Remove user IAM

attached to that node. If that volume can only be attached to one node at a
time (GCE PDs attached in RW mode, for example), then the volume must be
manually detached before Kubernetes can attach it to other nodes.
  * If a volume is already attached to a node any subsequent attempts to attach it
again (due to kubelet restart, for example) will fail. The volume must either
be manually detached first or the pods referencing it deleted (which would

         * In theory, cancel() could execute arbitrary listeners -- bad to do while holding a lock.
         * However, we don't expose currentFuture to users, so they can't attach listeners. And the
         * Future might not even be a ListenableFuture, just a plain Future. That said, similar
         * problems can exist with methods like FutureTask.done(), not to mention slow calls to

possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program. It is safest to
attach them to the start of each source file to most effectively convey
the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

   * nulls as long as the *last* element is *not* null.
   *
   * (To "go out of its way," the method tracks a `set` bit so that it can distinguish "the final
   * split has a last element of null, so throw NPE" from "the final split was empty, so look for an
   * element in the prior one.")
