	// Xcode is the version string that gets embedded into Xcode builds for the
	// Tailscale iOS app and macOS standalone (aka "macsys") app.
	//
	// It is the same as Short, but with 100 added to the major version number.
	// This is because Apple requires monotonically increasing version numbers,
	// and very early builds of Tailscale used a single incrementing integer,
	// which the Apple interprets as the major version number. When we switched
	// to the current scheme, we started the major version number at 100 (v0,
	// plus 100) to make the transition.
	Xcode string
	// XcodeMacOS is the version string that gets embedded into Xcode builds for
	// the Tailscale macOS app store app.
	//
	// This used to be the same as Xcode, but at some point Xcode reverted to
	// auto-incrementing build numbers instead of using the version we embedded.
	// As a result, we had to alter the version scheme again, and switched to
	// GitHash's commit date, in the format "YYYY.DDD.HHMMSS"
	XcodeMacOS string
	// Winres is the version string that gets embedded into Windows exe
	// metadata. It is of the form "x,y,z,0".

	// Track is the release track of this build: "stable" if the minor version
	// number is even, "unstable" if it's odd.
	Track string
	// MSIProductCodes is a map of Windows CPU architecture names to UUIDv5
	// hashes that uniquely identify the version of the build. These are used in
	// the MSI installer logic to uniquely identify particular builds.
