v4.1.0

CoinSelection now works for TaprootKeyInput and TaprootSingleScriptSigInput.

defaultSigHash may be used with InputCandidate to give an optimal fee for Taproot inputs signed with the default sighash.

v4.0.0

• The TaprootKeyInput will now write an empty witness stack element to represent a missing signature. These inputs without a signature will be recognised when matching an input or reading a transaction.
• TaprootSingleScriptSigInput.anyPrevOutAnyScript() has been removed. All TaprootSingleScriptSigInput inputs now require the Taproot and TapLeafChecksig.
• Fixes Windows build sometimes hanging

v3.1.0

• Add .r and .s getters to SchnorrSignature with a new .fromRS constructor. The underlying bytes for a BIP340 signature can be obtained via .r.x and .s.data.
• Add .xhex convenience getter for ECPublicKey.

v3.0.0

This release adds support for ANYPREVOUT and ANYPREVOUTANYSCRIPT. There have been numerous breaking changes.

• Refactored SigHashType to use OutputSigHashOption and InputSigHashOption. Adds ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Add TapLeafChecksig for single signature checksig tapscripts
• Add TaprootSingleScriptSigInput to sign tapscripts using TapLeafChecksig. Can sign using ANYPREVOUT and ANYPREVOUTANYSCRIPT.
• Replaced sign() with signLegacy(), signLegacyWitness(), signTaproot() and signTaprootSingleScriptSig().
• Added SignDetails with numerous subclasses for providing signing details for inputs. SignatureHasher subclasses and Input sign methods refactored accordingly.
• Taproot signatures are made using SIGHASH_DEFAULT by default.

v2.2.0

Add ECCompressedPublicKey class that forces compressed public keys.

v2.0.0
