* Fix typos and formatting errors in changelog
* Add requestAnimationFrame and remove "New helpful warnings"
**what is the change?:**
In response to helpful code review -
- Add mention of dependency on `requestAnimationFrame` and need to
polyfill that as well as `Map` and `Set`
- Remove "New helpful warnings" section; it was incomplete, and there
are so many new and updated warnings that it might not be reasonable
to cover them in the changelog.
