refactor(bip32): Xpub child tweak api

This commit is a straightforward API refactor in the BIP-32 (Bitcoin key derivation) code. It replaces a function that returned a raw secret key and chain code with one that returns a new structured type called XpubChildTweak. The actual c…

refactor(bip32): rename Xpub and Xpriv derivation methods

This is a routine code cleanup in a Bitcoin library. It renames key-derivation methods on extended public and private keys (Xpub/Xpriv) to clearer names and removes old aliases. There is no security bug being fixed and no new vulnerability…

Add try_push to Buffer trait

This commit adds a new `try_push` method to an internal `Buffer` trait used during Base58 encoding. It is a straightforward, additive change that lets encoding code gracefully handle a full fixed-size buffer in no-allocation builds. There …

consensus_encoding: Rename _with decoder functions

This commit is a simple renaming of internal Rust functions from names ending in '_with' to names ending in '_with_decoder'. It does not change what the code does, only what the functions are called, to avoid confusion with another functio…

2026-07-05 automated rustfmt nightly

This commit is a routine automated code-formatting run by the rustfmt tool. It only changes whitespace, import order, and line breaks in five files. There are no functional changes, no bug fixes, and no security-related modifications.

ci: adapt default and no feature bip32 test for rbmt 0.4.0

This is a routine update to the project's automated testing configuration. A tool used to run example tests changed its syntax, so the developer updated one line to keep the same tests running the same way. There is no user-facing change a…

Add {Lower,Upper}Hex to ecdsa::Signature

This commit adds new ways to print ECDSA Bitcoin signatures as hexadecimal text (lowercase and uppercase), matching formatting already available for Taproot signatures. It also makes the existing Display implementation reuse the new LowerH…

Add From/TryFrom for Signature/SerializedSignature

This commit adds standard Rust conversion traits (From/TryFrom) between an ECDSA signature and its serialized byte form. It is a small API-consistency change that mirrors traits already present on the Taproot signature type. There is no in…

Replace Signature Display with call to SerializedSignature

This commit fixes a formatting bug in how Bitcoin ECDSA signatures are printed as text. Previously, the signature was printed in two separate pieces (the DER-encoded signature and the sighash byte), which could mishandle formatting options…

Add PartialOrd, Ord to ecdsa::Signature

This commit simply adds standard sorting traits (PartialOrd and Ord) to an ECDSA signature type and its associated sighash type, matching what already exists for similar types. There is no indication this fixes or introduces a security pro…

Remove PrivateKeyExt and make PrivateKey::as_inner private

This commit is a routine API cleanup, not a security fix. It removes a helper trait called PrivateKeyExt and hides a low-level accessor method (as_inner) that exposes the underlying secret key object. The same signing behavior is preserved…

refactor: split bip32 xkey parse errors

This commit is a code cleanup: it splits one big error type into several smaller, more specific error types for BIP-32 extended key parsing. It does not change what the code accepts or rejects, only how errors are named and organized. Ther…

style: reorder bip32 error impls

This commit is a pure code-style change. It reorders the implementation blocks for several error types in a Bitcoin-related Rust library so that the order of traits (From, std::error::Error, Display, helper methods) is consistent. No logic…

Remove Encodable and Decodable impls for crate types

This commit removes old serialization/deserialization trait implementations (called Encodable and Decodable) from many Bitcoin data types in the rust-bitcoin library. It is described by the project as a cleanup step toward replacing the ol…

Replace uses of consensus in tests

This commit only changes test code and documentation examples in the rust-bitcoin library. It replaces older consensus encoding/decoding helper functions with newer equivalents from a different internal module. There is no change to produc…

Replace uses of bitcoin::consensus with consensus_encoding

This commit swaps out an older Bitcoin data-encoding system for a newer one across six files. It is a routine internal refactoring change. There is no direct evidence in the commit that it fixes a security vulnerability, but any encoding c…

Add XOnlyPublicKey::verify

This commit adds a new convenience method, XOnlyPublicKey::verify, that lets users verify Schnorr (taproot) signatures without calling the underlying secp256k1 library directly. It is a straightforward API addition with no obvious security…

Add tests to verify 0 return for overflow

This commit only adds new unit tests to verify that a previously changed function, Target::from_compact, returns zero when a Bitcoin 'compact' difficulty value overflows a 256-bit target. It does not change any production code. The tests c…

Return 0 on Target::from_compact overflow

This commit fixes a bug in how rust-bitcoin converts Bitcoin 'compact' difficulty targets into full numeric Target values. Previously, if the compact value encoded a number too large to fit in a valid Target, the code would silently produc…

refactor: split bip32 path parse errors

This commit is a code cleanup (refactor) that splits one combined error type into two separate error types for parsing BIP32 derivation paths. It does not change the actual parsing rules or fix any security bug. It only changes how error m…
