## [0.3.1.0] -- 2023-07-19

### Added
- Added support to `Data.Text`. ([#95](https://github.com/lsrcz/grisette/pull/95))
- Added `Arbitrary` instances for bit vectors. ([#97](https://github.com/lsrcz/grisette/pull/97))
- Added pretty printers for Grisette data types. ([#101](https://github.com/lsrcz/grisette/pull/101))
- Added `ExtractSymbolics` instances for tuples longer than 2. ([#103](https://github.com/lsrcz/grisette/pull/103))

### Fixed
- Fixed the `Read` instance for bit vectors. ([#99](https://github.com/lsrcz/grisette/pull/99), [#100](https://github.com/lsrcz/grisette/pull/100))

## [0.3.0.0] -- 2023-07-07

### Added
- Added the conversion between signed and unsigned bit vectors. ([#69](https://github.com/lsrcz/grisette/pull/69))
- Added the generation of `SomeSymIntN` and `SomeSymWordN` from a single `Int` for bit width. ([#73](https://github.com/lsrcz/grisette/pull/73))
- Added the `FiniteBits` instance for `SomeSymIntN` and `SomeSymWordN`. ([#83](https://github.com/lsrcz/grisette/pull/83))
- Added more flexible instances for symbolic generation for `Either`, `Maybe` and list types. ([#84](https://github.com/lsrcz/grisette/pull/84))
- Added an experimental `GenSymConstrained` type class. ([#89](https://github.com/lsrcz/grisette/pull/89))

### Changed
- Changed the operations for `SomeIntN` and `SomeWordN` to accepting dynamic runtime integers rather than compile-time integers. ([#71](https://github.com/lsrcz/grisette/pull/71))
- Comparing the equality of `SomeIntN`/`SomeWordN`/`SomeSymIntN`/`SomeSymWordN` with different bit widths returns false rather than crash now. ([#74](https://github.com/lsrcz/grisette/pull/74))

### Fixed
- Fixed the compatibility issue with sbv 10+. ([#66](https://github.com/lsrcz/grisette/pull/66))
- Fixed build error with newer GHC. ([#70](https://github.com/lsrcz/grisette/pull/70))
- Fixed the merging for `SomeSymIntN` and `SomeSymWordN`. ([#72](https://github.com/lsrcz/grisette/pull/72))

## [0.2.0.0] - 2023-04-13

### Added
- Add term size count API. ([#48](https://github.com/lsrcz/grisette/pull/48), [#53](https://github.com/lsrcz/grisette/pull/53))
- Add timeout to solver interface. ([#49](https://github.com/lsrcz/grisette/pull/49), [#50](https://github.com/lsrcz/grisette/pull/50))
- Add parallel do-notation for parallel symbolic compilation. ([#51](https://github.com/lsrcz/grisette/pull/51))
- Added some missing instances for symbolic values and bit vectors. ([#46](https://github.com/lsrcz/grisette/pull/46), [#61](https://github.com/lsrcz/grisette/pull/61))
- Add missing instances for `MonadFresh` and `FreshT`. ([#59](https://github.com/lsrcz/grisette/pull/59))

### Changed
- New safe operator interfaces. ([#56](https://github.com/lsrcz/grisette/pull/56))
- Redesigned symbolic value interface.
  - `Sym Bool`/`Sym Integer`, etc., are no longer available and are replaced with `SymBool` and `SymInteger`. ([#41](https://github.com/lsrcz/grisette/pull/41))
  - New symbolic bit vector interface. Added unsized bit vector. ([#41](https://github.com/lsrcz/grisette/pull/41))

### Removed
- Dropped merging cache for `UnionM`. This fixed some segmentation fault errors. ([#43](https://github.com/lsrcz/grisette/pull/43))

### Fixed
- Fix CEGIS when no symbolic input is present. ([#52](https://github.com/lsrcz/grisette/pull/52))
- Fix overlapping `ToSym` and `ToCon` instances. ([#54](https://github.com/lsrcz/grisette/pull/54))
