What changed, and why it matters
This commit only updates a documentation file (doc/bips.md) listing which Bitcoin Improvement Proposals (BIPs) are implemented in Bitcoin Core. It adds entries for BIPs 327, 328, 373, and 390, all related to MuSig2 multi-signature support. No code, logic, or configuration was changed, so this commit has no direct security impact.
Recommended action
No security action required. Treat as routine documentation maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is a pure documentation change to doc/bips.md, adding four rows to the BIP implementation matrix. The referenced BIPs (327, 328, 373, 390) describe MuSig2 key aggregation, derivation, PSBT fields, and descriptor parsing/signing. The actual implementation code was merged in earlier PRs (29675, 31244, 31247). This commit does not alter any executable code, build system, tests, or network behavior.
