ci: add bitcoin_hashes and bitcoin-network-kind to SEMVER_HARD_FAIL_CRATES

This commit only changes a CI script that lists which Rust crates must follow strict semantic-versioning rules. It adds two already-released 1.0 crates to the hard-fail list so future pull requests will fail automated checks if they accide…

ci: Scan bitcoin-network-kind for semver breaks

This commit only adds a new Rust package (bitcoin-network-kind) to an existing CI script that checks for accidental breaking changes in public APIs. It does not change any library code, runtime behavior, or security-sensitive logic. There …

This commit changes an internal CI script so that only major version-number-breaking API changes are flagged, while minor API changes are ignored. It is a workflow/process tweak with no effect on the actual Bitcoin library code that users …

hashes: Deprecate sha256t_tag macro

This is a routine code-maintenance change: the developers are marking an old helper macro as deprecated and telling users how to write the same code by hand. There is no bug fix, no security patch, and no vulnerability being addressed in t…

This commit fixes two broken type aliases (shortcut names) for HKDF, a cryptographic key-derivation helper, in the rust-bitcoin hashes library. The aliases were pointing at the wrong underlying type after a previous refactor, so any code t…

hashes: implement sha256t::Tag without the macro

This commit is a routine code cleanup in the rust-bitcoin library. It replaces a macro used to define SHA-256 tagged hash identifiers with direct Rust code that does the same thing. The actual hash values and behavior are unchanged; only t…

This commit adds a new convenience method called with_input to the hash engine API. It is purely a quality-of-life change that lets callers chain hash-input calls together. There is no security-relevant change: the existing input method st…

hashes: fix tag name in sha256t_tag macro docs

This is a one-word documentation fix in a Rust macro. The generated documentation for a cryptographic tag structure was accidentally referring to a non-existent variable name, so it displayed broken placeholder text like '[`$hash_name`]' i…

hashes: add one-shot hash method to HashEngine

This commit adds a small convenience method that lets any hash type compute a hash from a chunk of data in a single call. It is a pure API addition with no changes to existing behavior, no bug fixes, and no security-related content.
