5.0.0

This major bump brings a lot of internal improvements. Also, we extracted some integrations out of the SDKs and put them
in their own package called @sentry/integrations. For a detailed guide how to upgrade from 4.x to 5.x refer to our migration guide.

Migration from v4

If you were using the SDKs high level API, the way we describe it in the docs, you should be fine without any code
changes. This is a breaking release since we removed some methods from the public API and removed some classes from
the default export.
