Reading the time difference of the later I would assume that due to the active exploits on one has been informed prior - so no preparation. But it seems they are working on it.
There aren’t currently any 97.0.2 builds in koji or bodhi right now, but there is a Firefox 98 build that you can try if you really need an update now and can’t wait for QA.
I’m quite sure that the maintainers are aware of the bugs and their fixes—they work with upstream quite closely. From the commit activity, it looks like Firefox 98 is being prepared to be pushed to all Fedora releases.
