Yeah. "New" 5e (will work for a few years, after which you can probably just say "D&D").
"Want to play D&D? We use the latest stuff." Is
already what most people do (assuming that they even need the second sentence).
If you're someone who switches editions regularly (say, playing a 1e game occasionally, or whatever) you can say "2024" or just "24". A lot of people use "5.24" but that works better in the typing than it does in the speaking.
If you really have to, you could join those hooked on a marketing scheme from 20 years ago (like
@Maxperson above) and call it 5.5. I mean, I hate it, but anyone familiar with 3.5 will at least know what you mean by it...
