    @tzulitai I've reviewed the new subsection. I think it's fine as is.

> There needs to be a documentation that explains how to use the new serializer upgrade APIs in {{TypeSerializer}}, and how the methods work with checkpoints. This documentation should probably be placed under "Application development --> Streaming --> Working with State".
> Ideally, it should also come with a minimal example for users that perhaps use serialization frameworks that already have built-in backwards compatibility (such as Thrift).
