## [0.5.0] - 2024-05-06
11+
12+
#### Added
13+
- New function `secp256k1_ec_pubkey_sort` that sorts public keys using lexicographic (of compressed serialization) order.
14+
15+
#### Changed
16+
- The implementation of the point multiplication algorithm used for signing and public key generation was changed, resulting in improved performance for those operations.
17+
- The related configure option `--ecmult-gen-precision` was replaced with `--ecmult-gen-kb` (`ECMULT_GEN_KB` for CMake).
18+
- 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).
19+
20+
#### ABI Compatibility
21+
The ABI is backward compatible with versions 0.4.x and 0.3.x.

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.
