* Changes secret, configMap, downwardAPI and projected volumes to mount read-only, instead of allowing applications to write data and then reverting it automatically. Until version 1.11, setting the feature gate ReadOnlyAPIDataVolumes=false will preserve the old behavior. ([#58720](https://github.com/kubernetes/kubernetes/pull/58720), [@joelsmith](https://github.com/joelsmith))

- Upgraded `coredns` to `v1.11.1`. ([#120116](https://github.com/kubernetes/kubernetes/pull/120116), [@tukwila](https://github.com/tukwila))
- `EnqueueExtensions` from plugins other than `PreEnqueue`, `PreFilter`, `Filter`, `Reserve` and `Permit` are now ignored.
  It reduces the number of kinds of cluster events the scheduler needs to subscribe/handle. ([#121571](https://github.com/kubernetes/kubernetes/pull/121571), [@sanposhiho](https://github.com/sanposhiho))

* ✨ Allow custom middlewares to raise `HTTPException`s and propagate them. PR [#2036](https://github.com/tiangolo/fastapi/pull/2036) by [@ghandic](https://github.com/ghandic).

	// unsigned right shift (divide by two), convert, and
	// double. However, before we do that, we need to be
	// sure that we do not lose a "1" if that made the
	// difference in the resulting rounding. Therefore, we
	// preserve it, and OR (not ADD) it back in. The case
	// that matters is when the eleven discarded bits are
	// equal to 10000000001; that rounds up, and the 1 cannot
	// be lost else it would round down if the LSB of the
