## 0.9.1 (2023-08-17)
### Fixed
- `Scalar` conversion to `SecretKey` ([#137])

[#137]: https://github.com/RustCrypto/nacl-compat/pull/137

## 0.9.0 (2023-07-22)

COMPATIBILITY NOTE: previous versions of this crate provided a `ChaChaBox`
construction which is incompatible with the one in libsodium. This release
makes breaking changes to that construction which provide compatibility with
the libsodium implementation. No backwards compatibility is provided for the
construction in previous releases of this crate. We apologize for the
inconvenience.

### Added
- `SEALBYTES` constant ([#81])
- `serde` impl for `SecretKey` ([#101])
- Generic implementation of `CryptoBox` ([#113])

### Changed
- Use `crypto_secretbox` crate for symmetric cryptography ([#82], [#109])
- Replaced `x25519-dalek` with `curve25519-dalek` v4; MSRV 1.60 ([#88], [#130])
- Use `MontgomeryPoint` as `PublicKey`'s inner type ([#91])
- Make `seal` and `unseal` inherent methods ([#118])
  - `seal` => `PublicKey::seal`
  - `seal_open` => `SecretKey::unseal`
- Consistent constructors for `PublicKey`/`SecretKey` ([#119])

### Removed
- `rand_core` reexport ([#116])
