made me curious to what is meant by ref return. Is this a recent improvement in DMD?

No. We've been able to return by ref for ages. However, when std.datetime was originally written back in 2010, there were bugs that prevented it from working for a number of the functions in std.datetime. Unfortunately, I can't remember what the bugs were at this point, but they've long since been fixed, and I just finally got around to making it so that those functions in std.datetime return by ref instead of void.
