## Urgent Upgrade Notes 

### (No, really, you MUST read this before you upgrade)

- Fix: don't use docker config cache if it's empty ([#92330](https://github.com/kubernetes/kubernetes/pull/92330), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]
- Fix: initial delay in mounting azure disk & file ([#93052](https://github.com/kubernetes/kubernetes/pull/93052), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]

	randN = r
	randmu.Unlock()

by cert rotation were created in a combined PEM file that was atomically rotated as `kubelet-client-DATE.pem` in that directory, which meant clients relying on the `node.kubeconfig` generated by bootstrapping would never use a rotated cert.  The initial bootstrap certificate is now generated into the cert directory as a PEM file and symlinked to `kubelet-client-current.pem` so that the generated kubeconfig remains valid after rotation.

- Cloud controller manager's node controller now emits timing metrics for initial `Node` synchronization. These metrics measure the delay between the creation of a new `Node` and the node controller's initial management actions, such as removing the cloud provider taint. These metrics should be consulted when setting cloud controller manager's `--concurrent-node-syncs` flag. ([#119241](ht...

* x509 authenticator: get groups from subject's organization field ([#30392](https://github.com/kubernetes/kubernetes/pull/30392), [@ericchiang](https://github.com/ericchiang))
* Add initial support for TokenFile to the client config file. ([#29696](https://github.com/kubernetes/kubernetes/pull/29696), [@brendandburns](https://github.com/brendandburns))

- Fixed #118052: nodeAffinity on pods can change prior to scheduling gates being removed even when podSpec.affinity is nil in the initial spec, this matches the 1.28 behavior to allow consistent integrators to be written. ([#118199](https://github.com/kubernetes/kubernetes/pull/118199), [@aleskandro](https://github.com/aleskandro)) [SIG Apps, Scheduling and Testing]

- Client-go/reflector: warns when the bookmark event for initial events hasn't been received ([#124614](https://github.com/kubernetes/kubernetes/pull/124614), [@p0lyn0mial](https://github.com/p0lyn0mial)) [SIG API Machinery]
