* Generics migration This attempts to migrate this library in the least invasive way by preserving as much of the original API as possible. It does not change the tests in a meaningful way nor does it attempt to upgrade any logic that can be simplified or improved with generics. This is purely an API migration, and still requires a lot of additional work to be fully ready. * Fix a few broken tests around serialization * Add v2 suffix * Temporarily change mod name for testing * Rename module to /v2
