v0.29.1

Compare Source

v0.29.0

Compare Source

• Deprecate ThirtyTwoByteHash #​686

  This trait turned out to be problematic during upgrade because we support a ranged dependency for
  bitcoin_hashes. Consider implementing From<T> for Message for your type iff your type is a 32
  byte hash (ie, output from a hash algorithm that produces a 32 byte digest like sha256). When
  using the impl, consider using Message::from instead of hash.into() because we will be
  introducing generics in a future version and the compiler will not be able to work out the target
  type.

• Bump MSRV to Rust v1.56.1 #​693

• Upgrade hashes using range dependency version = ">= 0.12, <= 0.14" #​690

• Depend on latest secp256k1-sys (vendors secp256k1 v0.4.1) #​688

v0.28.2

Compare Source

• Implement Hash for Scalar #​674
• Implement Ord and PartialOrd for RecoverableSignature #​611
• Add byte accessors to ElligatorSwiftSharedSecret #​676

v0.28.1

Compare Source

• Update secp265k1-sys to 0.9.2 (contains some fixes for WASM and a FFI binding fix)
• Various improvements to the SerializedSignature type #​658 #​659

v0.28.0

Compare Source

• Add bindings to the ElligatorSwift implementation #​627
• Depend on recent release of bitcoin_hashes v0.13.0 #​621
• Add a verify function to PublicKey #​618
• Add serialize function for schnorr::Signature #​607
• Bump MSRV to 1.48 #​595
• Remove implementations of PartialEq, Eq, PartialOrd, Ord, and Hash from the
  impl_array_newtype macro. Users will now need to derive these traits if they are wanted.
