## [Unreleased]
## [0.3.1] - 2023-04-10
We strongly recommend updating to 0.3.1 if you use or plan to use Clang >=14 to compile libsecp256k1, e.g., Xcode >=14 on macOS has Clang >=14. When in doubt, check the Clang version using `clang -v`.
#### Security
- Fix "constant-timeness" issue with Clang >=14 that could leave applications using libsecp256k1 vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow and secret-dependent memory accesses in conditional moves of memory objects when libsecp256k1 is compiled with Clang >=14.
#### Added
- Added tests against [Project Wycheproof's](https://github.com/google/wycheproof/) set of ECDSA test vectors (Bitcoin "low-S" variant), a fixed set of test cases designed to trigger various edge cases.
#### Changed
- Increased minimum required CMake version to 3.13. CMake builds remain experimental.
#### ABI Compatibility
The ABI is compatible with version 0.3.0.
## [0.3.0] - 2023-03-08
@ -25,7 +38,6 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
- Removed the configuration header `src/libsecp256k1-config.h`. We recommend passing flags to `./configure` or `cmake` to set configuration options (see `./configure --help` or `cmake -LH`). If you cannot or do not want to use one of the supported build systems, pass configuration flags such as `-DSECP256K1_ENABLE_MODULE_SCHNORRSIG` manually to the compiler (see the file `configure.ac` for supported flags).
#### ABI Compatibility
Due to changes in the API regarding `secp256k1_context_static` described above, the ABI is *not* compatible with previous versions.
## [0.2.0] - 2022-12-12
@ -45,7 +57,6 @@ Due to changes in the API regarding `secp256k1_context_static` described above,
- Module `schnorrsig`: renamed `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`.
#### ABI Compatibility
Since this is the first release, we do not compare application binary interfaces.
However, there are earlier unreleased versions of libsecp256k1 that are *not* ABI compatible with this version.
