Did Joe Johnson retire from the NBA?

I do not keep up with the NBA except for a hog or two and wonder if he retired at the end of last season etc.
He sure made a ton of money.

There were reports this summer that he wanted to continue playing but I don’t think anyone has picked him up. Call him involuntarily retired at this point.

Thanks, I assumed frankly his days were over, he is just not a young guy who a team might want for the future.
