Zeit Now: Long expiration date for static assets

now.newer-properties.json

{
	"version": 2,
	"trailingSlash": true,
	"headers": [
		{
			"source": "/(.*)\\.(js|css|map|json|ico)",
			"headers" : [
				{
					"key" : "Cache-Control",
					"value" : "public, max-age=31536000, immutable"
				}
			]
		}
	],
	"redirects": [
		{
			"source": "/favicon.ico",
			"destination": "/favicon.ico",
			"statusCode": 204
		}
	]
}

now.older-properties.json

{
	"version": 2,
	"routes": [
		{
			"src": "/(.*)\\.(js|css|map|json|ico)$",
			"headers": { "Cache-Control": "public, max-age=31536000, immutable" },
			"continue": true
		},
		{
			"src": "/favicon.ico",
			"dest": "/favicon.ico",
			"status": 204
		},
		{
			"handle": "filesystem"
		}
	]
}

Both versions work at the moment, but routes is getting deprecated in favor of properties like headers, redirects, rewrites, trailingSlash (and handle: filesystem isn't needed anymore with newer properties).
