Description

After upgrading to React 17, I get that warning from yarn:

warning " > @sentry/react@5.27.2" has incorrect peer dependency "react@15.x || 16.x".
warning " > @sentry/react@5.27.2" has incorrect peer dependency "react-dom@15.x || 16.x".

Same thing here. 👍

According to https://reactjs.org/blog/2020/10/20/react-v17.html#no-new-features there should be nothing that stops us from just adding 17.x to the list I guess?

@kamilogorek that should be the case, yes. I'm using 5.27.2 with React 17 in some projects without issues, although I'm not using all the exposed features of the package so there might be some edge cases I haven't run into.
