v0.10.1

• Update Orion to 0.17 which includes Poly1305 implementation based on formally verified arithmetic from fiat-crypto (@brycx).
• Test implementation with now standardized test vectors from the spec (@brycx).
• Bump MSRV to 1.52 (@brycx).
• Enable Dependabot to automatically check for updates for dependencies (@brycx).

v0.10.0

• Fix stack overflow occurring from incorrect Display implementation (@aldebaranzbradaradjan #14)
• Fix non-propagated error in Branca.encode (@brycx #12)
• Fix issue with compliance to the specification: Allow empty input when encoding & decoding tokens (@brycx #13)
• MSRV bumped to 1.41
• (Breaking change): Correctly handle binary data (@ganwell #10 (fix by @brycx)). Previously, non-UTF8 encoded tokens would not decode to the correct payload if the token was created with a different Branca implementation.
• (Security): Correctly return error on invalid base62 tokens. Previously, this would panic whereas documentation would indicate an error was supposed to be returned (@brycx 7da3274)
• Document that encode() panics if it fails to generate random bytes for the nonce.
• Add basic fuzzing targets (@brycx #17)
• (Breaking change): Fix that the nonce, returned by the builder context, was never used for encoding (@brycx #19)
• (Breaking change): Return OverflowingOperation error if adding TTL to timestamp would overflow (@brycx #21)
• Fix incorrect timestamps used for token creation with Branca struct (@brycx #22)

v0.9.2

• Token expiration is now checked after authentication and decryption to remove the impossibility of knowing if an expired token is valid or not. (Credit: @brycx #8)
• Updated Branca dependencies. f3d348f
• Replaced .description() with .to_string() to remove warnings in Rust 1.45.2 971364f
• Use as_secs() in Branca::new() #9
• More test vectors from the JS implementation were added #6

v0.9.1

• Fix Invalid ExpiredToken error logic (#3)
• Update orion to v0.15 (#4) (Now 0.15.1)
• Change summary of TTL in documentation.
• Update branca dependencies.
• Migrate to GitHub Actions from Travis.

v0.9.0

• Replaced Ring and chacha20-poly1305 crates with Orion by @brycx (#1)
  • Brings Unofficial Windows / WSL Support. (A Windows CI will be added to support this.)
  • Secret key comparison runs in constant-time with manual PartialEq implementation.
  • Also removes the internal hChaCha20 implementation.
• (Breaking Change) Removed set_nonce() API.
• Examples and tests now integrated into library.
• Various Documentation fixes (Rustdoc friendly).

v0.8.0

• Added Branca::new() interface to simplify generating Branca tokens.
• Migrated Key and Nonce fields from Vec to &[u8] in exception to the Branca struct.
• Self variable in Branca struct is now borrowed rather than owned.
• hChaCha20 module is now a private module. (Only needed internally by the encode/decode) methods.
• Branca now uses Ring for nonce generation
• Added Documentation to all fields.

v0.5.0

• Implementation is now written in Pure Rust (Zero unsafe code or FFI usage)
  • Migrated to chacha-poly1305-aead crate with in-tree hchacha20 implementation by @tarcieri
• Message data type changed from String --> &str.
• Removed sodiumoxide.
• Switched from chrono --> std::time for timestamps.
• Added more tests and examples.
• Typical bug fixes and bounds checks for the keys and nonces.

v0.2.0

• Now uses sodiumxide for XChaCha20-Poly1305 cryptography functions.
• Switched Key type to using a Vec instead of a String.
• Added Travis CI.

v0.1.1

Initial release.
