## Changelog since v1.20.0-alpha.0

## Urgent Upgrade Notes

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

	// struct <name>__{int unused;}; typedef struct <name>__ *name;
	//
	// by the DECLARE_HANDLE macro in STRICT mode. The macro is declared in
	// the Windows ntdef.h header,
	//
	// https://github.com/tpn/winsdk-10/blob/master/Include/10.0.16299.0/shared/ntdef.h#L779
	if goos != "windows" {
		return false
	}
	if len(dt.Field) != 1 {
		return false
	}
	if dt.StructName != name+"__" {
		return false
	}

### Deprecation of FlexVolume

FlexVolume is deprecated. Out-of-tree CSI driver is the recommended way to write volume drivers in Kubernetes.
See [this doc](https://github.com/kubernetes/community/blob/master/sig-storage/volume-plugin-faq.md#kubernetes-volume-plugin-faq-for-storage-vendors) for more information.
Maintainers of FlexVolume drivers should implement a CSI driver and move users of FlexVolume to CSI.
