Re: [racket-dev] 5.0.2 changelog
I don't agree with this. We put something in there. It has been there for a full release cycle and we still don't have documentation. Choosing to not mention it is not reasonable. Instead I think a bullet like this is what we should put: * signatures have been restricted to ASL (removed from BSL and ISL and variants). Possibly we should also put something about why (so SK can experiment).
