Do you still need to take a covid test before boarding a plane?

I live in Illinois, and will be traveling to Pennsylvania, I heard that they brought back the mask mandate so now I'm curious if I will have to do the test. I'm fully vaccinated even had the the booster shot. I checked online but I'm not 100% sure if the website has been updated or anything.
