Just tried bumping up my React Native project to 1.10.741.
The compilation seems to get stuck (doesn't finish, I waited a bunch and usually only takes a few seconds) at the following warnings (which are new, do not appear with ClojureScript 1.10.597).

It might be a Figwheel issue but I'm not sure, decided to post here in case somebody has a similar problem or a solution.
