Added — Language Bindings (12 languages, 41-function C API parity)
Java — 22 new JNI functions + 3 helper classes (RecoverableSignature, WifDecoded, TaprootOutputKeyResult): full coverage of ECDSA sign/verify, DER encoding, recovery, ECDH, Schnorr, BIP-32, BIP-39, taproot, WIF, address encoding, tagged hash
Swift — 20 new functions: DER encode/decode, recovery sign/recover, ECDH, tagged hash, BIP-32/39, taproot, WIF, address encoding
React Native — 15 new functions: DER, recovery, ECDH, Schnorr, BIP-32/39, taproot, WIF, address, tagged hash
Python — 3 new functions: ctx_clone(), last_error(), last_error_msg()
Rust — 2 new functions: last_error(), last_error_msg()
Dart — 1 new function: ctx_clone()
Go, Node.js, C#, Ruby, PHP — already complete (verified, no changes needed)
9 new binding READMEs — c_api, dart, go, java, php, python, ruby, rust, swift
Selftest report API — SelftestReport and SelftestCase structs in selftest.hpp; tally() refactored for programmatic reporting
Fixed — Documentation & Packaging
Package naming corrected across all documentation — libsecp256k1-fast* → libufsecp* (apt, rpm, arch); CMake target secp256k1-fast-cpu → secp256k1::fast; linker flag -lsecp256k1-fast-cpu → -lfastsecp256k1; pkg-config Libs -lsecp256k1-fast-cpu → -lfastsecp256k1
RPM spec renamed — libsecp256k1-fast.spec → libufsecp.spec
Debian control — source libufsecp, binary packages libufsecp3/libufsecp-dev
Arch PKGBUILD — pkgname=libufsecp, provides=('libufsecp')
3 existing binding READMEs fixed — Node.js, C#, React Native: removed inaccurate CT-layer claims (C API uses fast:: path only)
README dead link — INDUSTRIAL_ROADMAP_WORKING.md → ROADMAP.md
Fixed — CI / Build
-Werror=unused-function — added [[maybe_unused]] to get_platform_string() in selftest.cpp
Scorecard CI — pinned ubuntu:24.04 by SHA digest in Dockerfile.local-ci
