9.0.0 (2024-04-08)

🛑 Breaking changes

• update Reducer, Transducer and other types (95c43f3)
• BREAKING CHANGE: update generics in Reducer, Transducer and other types
  • swap generic type args in Reducer and IReducible to be same order as in Transducer, IXform, i.e. Reducer<A, B> maps items from type A to type B, not the other way (as was)!
  • this new order is more logical, less confusing and also in line with upcoming async transducers pkg
  • changes in userland should be minimal (if any), only impacted are custom reducer definitions
  • update all pkg internal occurrences
  • various other small refactorings, type/arg updates, e.g.
    • add generics for reduced()/ensureReduced()/unreduced()
    • update step() return type (incl. undefined)
    • add StructField generics
