Changelog for libsecp256k1-2-0.5.1-13.1.x86_64.rpm :

* Fri Aug 02 2024 Michael Vetter - Update to 0.5.1:
* Added usage example for an ElligatorSwift key exchange.
* The default size of the precomputed table for signing was changed from 22 KiB to 86 KiB. The size can be changed with the configure option --ecmult-gen-kb (SECP256K1_ECMULT_GEN_KB for CMake).
* \"auto\" is no longer an accepted value for the --with-ecmult-window and --with-ecmult-gen-kb configure options (this also applies to SECP256K1_ECMULT_WINDOW_SIZE and SECP256K1_ECMULT_GEN_KB in CMake). To achieve the same configuration as previously provided by the \"auto\" value, omit setting the configure option explicitly.
* Fixed compilation when the extrakeys module is disabled.
* The ABI is backward compatible with versions 0.5.0, 0.4.x and 0.3.x.
* Tue May 07 2024 Michael Vetter - Update to 0.5.0: Added:
* New function secp256k1_ec_pubkey_sort that sorts public keys using lexicographic (of compressed serialization) order. Changed:
* The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations. The related configure option --ecmult-gen-precision was replaced with - -ecmult-gen-kb (ECMULT_GEN_KB for CMake). This changes the supported precomputed table sizes for these operations. The new supported sizes are 2 KiB, 22 KiB, or 86 KiB (while the old supported sizes were 32 KiB, 64 KiB, or 512 KiB). ABI Compatibility:
* The ABI is backward compatible with versions 0.4.x and 0.3.x.
* Fri Dec 22 2023 Michael Vetter - Update to 0.4.1:
* The point multiplication algorithm used for ECDH operations (module ecdh) was replaced with a slightly faster one.
* Optional handwritten x86_64 assembly for field operations was removed because modern C compilers are able to output more efficient assembly. This change results in a significant speedup of some library functions when handwritten x86_64 assembly is enabled (--with-asm=x86_64 in GNU Autotools, -DSECP256K1_ASM=x86_64 in CMake), which is the default on x86_64. Benchmarks with GCC 10.5.0 show a 10% speedup for secp256k1_ecdsa_verify and secp256k1_schnorrsig_verify.
* Thu Dec 07 2023 Michael Vetter - Update to 0.4.0: Added:
* New module ellswift implements ElligatorSwift encoding for public keys and x-only Diffie-Hellman key exchange for them. ElligatorSwift permits representing secp256k1 public keys as 64-byte arrays which cannot be distinguished from uniformly random. See: + Header file include/secp256k1_ellswift.h which defines the new API. + Document doc/ellswift.md which explains the mathematical background of the scheme. + The paper on which the scheme is based.
* We now test the library with unreleased development snapshots of GCC and Clang. This gives us an early chance to catch miscompilations and constant-time issues introduced by the compiler (such as those that led to the previous two releases). Fixed:
* Fixed symbol visibility in Windows DLL builds, where three internal library symbols were wrongly exported. Changed:
* When consuming libsecp256k1 as a static library on Windows, the user must now define the SECP256K1_STATIC macro before including secp256k1.h. ABI Compatibility:
* This release is backward compatible with the ABI of 0.3.0, 0.3.1, and 0.3.2. Symbol visibility is now believed to be handled properly on supported platforms and is now considered to be part of the ABI.- Drop Export_SHA256_functions.patch- Drop _service file: no need with regular versioned releases
* Sun Jul 10 2022 Mark Stopka - Remove TODO file from %doc
