* Line width is 140 characters
* Lines of code surrounded by `// tag::NAME` and `// end::NAME` comments are included
  in the documentation and should only be 76 characters wide not counting
  leading indentation. Such regions of code are not formatted automatically as
  it is not possible to change the line length rule of the formatter for
  part of a file. Please format such sections sympathetically with the rest

		case cur.endOffset() > size:
			return false // Region extends beyond the actual size
		case pre.endOffset() > cur.Offset:
			return false // Regions cannot overlap and must be in order
		}
		pre = cur

// alignSparseEntries mutates src and returns dst where each fragment's

//
// If the current file is sparse and r is an io.ReadSeeker,
// then readFrom uses Seek to skip past holes defined in Header.SparseHoles,
// assuming that skipped regions are all NULs.
// This always reads the last byte to ensure r is the right size.
//
// TODO(dsnet): Re-export this when adding sparse file support.

- Added regions ap-northeast-3 and eu-west-3 to the list of well known AWS regions. ([#70252](https://github.com/kubernetes/kubernetes/pull/70252), [@nckturner](https://github.com/nckturner))

    Federation control system then creates and maintains a single
    global virtual IP to load balance incoming HTTP(S) traffic across
    some or all the registered clusters, across all regions. Google's
    GCE L7 LoadBalancer is the first supported implementation, and
	is available in this release.

- Fixed CSI migration of Azure Disk in-tree StorageClasses with topology requirements in Azure regions that do not have availability zones. ([#109154](https://github.com/kubernetes/kubernetes/pull/109154), [@jsafrane](https://github.com/jsafrane))

*   Azure NSG rules can be consolidated to reduce the likelihood of hitting Azure resource limits (available only in regions where the Augmented Security Groups preview is available).  ([#55740](https://github.com/kubernetes/kubernetes/pull/55740), [@itowlson](https://github.com/itowlson))
