## 0.3.1
### New Additions
- Added `CharStrategy::new_borrowed`.
## 0.3.0
### New Additions
- `Union` now supports weighting via `Union::new_weighted`. Corresponding
syntax to specify weights is also available in `prop_oneof!`.
- Added `TupleUnion`, which works like `Union` but permits doing static
dispatch even with heterogeneous delegate strategies.
- `prop_oneof!` is smarter about how it combines the input strategies.
- Added `option` module to generate weighted or unweighted `Option` types.
- Added `result` module to generate weighted or unweighted `Result` types.
- All `bits` submodules now have a `masked` function to create a strategy for
generating subsets of an arbitrary bitmask.
### Potential Breaking Changes
- `Union::new` now has a generic argument type which could impact type
inference.
- The concrete types produced by `prop_oneof!` have changed.
- API functions which used to return `BoxedStrategy` now return a specific
type.
- `BitSetStrategy<T>` is no longer `Copy` for non-`Copy` types `T` nor `Debug`
for non-`Debug` types `T`.
- `BitSetLike::max` has been renamed to `BitSetLike::len`.
## 0.2.1
### New Additions
- Added `prop_assert!` macro family to assert without panicking, for quieter
test failure modes.
- New `prelude` module for easier importing of important things.
- Renamed `Singleton` to `Just`. (The old name is still available.)
- Failure messages produced by `proptest!` are now much more readable.
- Added in-depth tutorial.
## 0.2.0
### Breaking Changes
- `Strategy` now requires `std::fmt::Debug`.
### New Additions
- `Strategy` now has a family of `prop_flat_map()` combinators for producing
dynamic and higher-order strategies.
- `Strategy` has a `prop_recursive()` combinator which allows generating
recursive structures.
- Added `proptest::bool::weighted()` to pull booleans from a weighted
distribution.
- New `prop_oneof!` macro makes it easier to select from one of several
strategies.
- New `prop_compose!` macro to simplify writing most types of custom
strategies.
## 0.1.1
### New Additions
Add `strategy::NoShrink`, `Strategy::no_shrink()`.
