Starting in 2020, no one on the planet wanted to name their product "Anything 2020" and since it was slipping a bit at the time, they went with CF2021. We've kept that cadence and naming. Now all future versions will be on the "odds" every 2 years. So CF2023, CF2025, etc. And, hopefully, when we hit the next prime, maybe we can have a nice surprise for folks. 😉
