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](https://github.com/getsentry/sentry-javascript/blob/master/MIGRATION.md).
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
