This is a completely re-written version of Joken that focused on:

- Performance:
  - avoid setting encoder everytime
  - use Jason
  - use benchmarks to find bottlenecks
- Portability of configuration:
  - previous versions made it awkward to pass configuration forward
  - the new module approach makes it easier to think about tokens
  - Enhanced typespecs
- Extensibility
  - a new hook system
  - JWKS as a hook (new library)
- Documentation
  - A series of guides to ease on adopting Joken2

And many other things... check the CHANGELOG.md file and the
