Yeah, updates to the Unicode database are generally pretty low-impact. For some time now, the properties of all existing characters have been frozen -- the updates are just adding new characters, most of which are either 1) extremely obscure languages that you'll probably never run into or 2) emoji. Either way, you're unlikely to see anything go horribly wrong because you're using an older version of the Unicode standard. Time zones, on the other hand...
