Released YYYY-MM-DD.
Released 2020-01-22.
This is technically a breaking change, but we expect that nearly everyone should be able to upgrade without any compilation errors. The only exception is if you were implementing the Arbitrary::size_hint method by hand. If so, see the “changed” section below and the API docs for Arbitrary::shrink for details.
arbitary::size_hint::recursion_guard helper function for guarding against infinite recursion in size_hint implementations for recursive types.Arbitrary::size_hint signature now takes a depth: usize parameter. This should be passed along unmodified to any nested calls of other size_hint methods. If you're implementing size_hint for a recursive type (like a linked list or tree) or a generic type with type parameters, you should use the new arbitrary::size_hint::recursion_guard helper function.size_hint implementations from #[derive(Arbitrary)] for recursive types.Released 2020-01-16.

Unstructured::int_in_range that would incorrectly trigger when given valid ranges of length one.Released 2020-01-14.
Released 2020-01-14.
"derive" cargo feature, to enable #[derive(Arbitrary)] for custom types. Enabling this feature re-exports functionality from the derive_arbitrary crate.Arbitrary implements the shrink method for you now.Arbitrary for std types implement shrinking now.Arbitrary::arbitrary_take_rest method allows an Arbitrary implementation to consume all of the rest of the remaining raw input. It has a default implementation that forwards to Arbitrary::arbitrary and the custom derive creates a smart implementation for your custom types.Arbitrary::size_hint method for hinting how many raw bytes an implementation needs to construct itself. This has a default implementation, but the custom derive creates a smart implementation for your custom types.Unstructured::choose method to choose one thing among a set of choices.Unstructured::arbitrary_len method to get an arbitrary length for a collection of some arbitrary type.Unstructured::arbitrary_iter method to create an iterator of arbitrary instance of some type.Arbitrary trait was simplified a bit.Unstructured is a concrete type now, not a trait.RingBuffer and FiniteBuffer are removed. Use Unstructured instead.Arbitrary implementation for char.Arbitrary implementation for String.
