They just released the beta of Office 2024, so no. However, they have drastically shortened the support lifecycle for offline editions which has made it a lot more expensive to use non-subscription Office. Office 2016 was supported for ten years, Office 2021 is supported for five.

With a three year release cycle, you used to be able to skip up to two versions of Office and still get security updates. Now you can't skip any because five years of support is too short to get you to the release six years out.
