## Changelog since v1.22.7

## Changes by Kind

### API Change

- Kubernetes api-server now merges selectors built from matchLabelKeys into the labelSelector of topologySpreadConstraints, 

		return xhttp.AmzChecksumTypeFullObject
	}
	if c.IsSet() {
		return xhttp.AmzChecksumTypeComposite
	}
	return ""
}

// CanMerge will return if the checksum type indicates that checksums can be merged.
func (c ChecksumType) CanMerge() bool {
	return c.Is(ChecksumCRC64NVME) || c.Is(ChecksumCRC32C) || c.Is(ChecksumCRC32)
}

// Hasher returns a hasher corresponding to the checksum type.

### Don't worry about style { #dont-worry-about-style }

* Don't worry too much about things like commit message styles, I will squash and merge customizing the commit manually.

* Also don't worry about style rules, there are already automatized tools checking that.
