libsecp256k1/CHANGELOG.md

@@ -5,6 +5,31 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [0.8.0] - 2026-08-03
+
+#### Added
+ - New function `secp256k1_context_set_sha256_compression` for overriding the internal SHA256 compression function used by the library at runtime (e.g., to route SHA256 through a hardware-accelerated implementation).
+ - New module `silentpayments` implements sending and receiving of Silent Payments according to [BIP 352](https://github.com/bitcoin/bips/blob/master/bip-0352.mediawiki). See:
+   - Header file `include/secp256k1_silentpayments.h` which defines the new API.
+   - Usage example `examples/silentpayments.c`.
+ - The `silentpayments` API currently requires full access to the transaction data (light client scanning is not implemented).
+
+#### Fixed
+ - Module `ellswift`: `secp256k1_ellswift_xdh` now treats secret keys greater than or equal to the curve order as invalid and returns 0 as documented. Previously, keys greater than the curve order were silently reduced modulo the order and accepted. The probability that a securely generated key is greater than the curve order is negligible, and thus the old behavior does not constitute a security issue.
+
+#### Changed
+ - The field multiplication and squaring routines of the 5x52 (64-bit) implementation are now force-inlined. This speeds up many library functions with GCC and MSVC (Clang is largely unaffected), e.g. `secp256k1_ecdsa_verify` and `secp256k1_schnorrsig_verify` by up to ~11%, at the cost of a somewhat larger compiled library. Force-inlining is disabled in unoptimized builds and when optimizing for size.
+ - CMake: Shared libraries built with CMake on OpenBSD and NetBSD now create the full versioned filename (e.g. `libsecp256k1.so.6.2` instead of `libsecp256k1.so.6`) and symlink chain, matching the behavior of GNU Autotools builds.

+#### Removed
+- Removed previously deprecated pointer `secp256k1_context_no_precomp`. Use `secp256k1_context_static` instead.
+- Removed previously deprecated function alias `secp256k1_schnorrsig_sign`. Use `secp256k1_schnorrsig_sign32` instead.
+- Removed macro `SECP256K1_GNUC_PREREQ` defined in the header file `include/secp256k1.h`. This macro was used in the library headers to check for GNU C extensions. The macro was not actually meant to be part of the public API of libsecp256k1. If you happened to use it in your code nevertheless, use the macros `__GNUC__` and `__GNUC_MINOR__` (defined by compilers with GNU C extensions) directly, or copy the macro definition from an old libsecp256k1 header file into your code.

+#### ABI Compatibility
+The symbols `secp256k1_context_no_precomp` and `secp256k1_schnorrsig_sign` were removed.
+Otherwise, the library maintains backward compatibility with versions 0.7.0 and 0.7.1.
