Prusa released firmware version 7.0.0 for most of their printers, and they say it has some security fixes that warranted giving people time to update their printers first before publishing the release to GitHub.
My CORE One is 100% local only so probably not a concern, but I'm still updating it now and not waiting.

N.B. on https://help.prusa3d.com/downloads you have to press "More" and find the specific model/variant if it isn't shown.
