8.x to 9.0
==========

*   Internal: The project was ported to TypeScript.
*   Always build a legacy and a modern JS build.
*   Removed the ability to use the project's `tsconfig.json`. 
*   Removed `disableChunkSplitting()`, chunk splitting is now always disabled. Use code splitting instead and remove the call to this method.
*   Now no npm package is built anymore. Define your npm packages that need a transformation via `.compileNpmPackages(...)` (for now only top-level entries support, so either complete vendor or global package name).


7.x to 8.0
==========

*   Removed `enableTypeScript()`. Remove it without replacement, as it is now automatically enabled.
*   Removed `setBrowserList()`. Set the `browserlist` config in your project's `package.json` instead.
