## [Unreleased]

## [0.3.2] - 2023-05-13
We strongly recommend updating to 0.3.2 if you use or plan to use GCC >=13 to compile libsecp256k1. When in doubt, check the GCC version using `gcc -v`.

#### Security
- Module `ecdh`: Fix "constant-timeness" issue with GCC 13.1 (and potentially future versions of GCC) that could leave applications using libsecp256k1's ECDH module vulnerable to a timing side-channel attack. The fix avoids secret-dependent control flow during ECDH computations when libsecp256k1 is compiled with GCC 13.1.

#### Fixed
- Fixed an old bug that permitted compilers to potentially output bad assembly code on x86_64. In theory, it could lead to a crash or a read of unrelated memory, but this has never been observed on any compilers so far.

#### Changed
- Various improvements and changes to CMake builds. CMake builds remain experimental.
- Made API versioning consistent with GNU Autotools builds.
- Switched to `BUILD_SHARED_LIBS` variable for controlling whether to build a static or a shared library.
- Added `SECP256K1_INSTALL` variable for the controlling whether to install the build artefacts.
- Renamed asm build option `arm` to `arm32`. Use `--with-asm=arm32` instead of `--with-asm=arm` (GNU Autotools), and `-DSECP256K1_ASM=arm32` instead of `-DSECP256K1_ASM=arm` (CMake).

#### ABI Compatibility
The ABI is compatible with versions 0.3.0 and 0.3.1.

## [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`.

The number was given by the build system since the introduction of autotools in Jan 2014 (ea0fe5a5bf0c04f9cc955b2966b614f5f378c6f6).
Therefore, this version number does not uniquely identify a set of source files.
