  Below we will outline all the breaking changes you should consider when upgrading.
  **TL;DR** If you only use basic features of Sentry, or you simply copy & pasted the setup examples from our docs, here's what changed for you:
  +- If you installed additional Sentry packages, such as`@sentry/tracing` alongside your Sentry SDK (e.g. `@sentry/react` or `@sentry/node`), make sure to upgrade all of them to version 7.
  - Our CDN bundles are now ES6 - you will need to [reconfigure your script tags](#renaming-of-cdn-bundles) if you want to keep supporting ES5 and IE11 on the new SDK version.
  - Distributed CommonJS files will be ES6. Use a transpiler if you need to support old node versions.
  - We bumped the TypeScript version we generate our types with to 3.8.3. Please check if your TypeScript projects using TypeScript version 3.7 or lower still compile. Otherwise, upgrade your TypeScript version.
