v2.2.0

Added

• New Cardano-specific fuzzers covering: (@KtorZ, @Riley-Kilgore)

  • Address
  • Assets
  • Certificate
  • Transaction

• New chaos-testing framework under aiken/fuzz/scenario (@KtorZ, @Riley-Kilgore)

• New data() -> Fuzzer<Data> (@KtorZ)

v2.1.1

Added

More primitives for fuzzers:

• tuple,tuple3, tuple4, tuple5, tuple6, tuple7, tuple8, tuple9 @ariady-putra

v2.1.0

Added

• More primitives for combining fuzzers:
  • either2, either3, either4, either5, either6, either7, either8, either9
  • pick(xs: List<a>) -> Fuzzer<(Int, a)>
  • label_if(str: String, predicate: Bool) -> Void

Changed

• Have bytearray primitives simplify towards the null bytestring (32 zeroes),
  so that it's easier to identify in simplified examples.

v2.0.0

Changed

• Integrated with aiken==1.1.0 and aiken-lang/stdlib==v2
