## [Unreleased]

10+
#### Added
11+
- New module `ellswift` implements ElligatorSwift encoding for public keys and x-only Diffie-Hellman key exchange for them.
12+
ElligatorSwift permits representing secp256k1 public keys as 64-byte arrays which cannot be distinguished from uniformly random. See:
13+
- Header file `include/secp256k1_ellswift.h` which defines the new API.
14+
- Document `doc/ellswift.md` which explains the mathematical background of the scheme.
15+
- The [paper](https://eprint.iacr.org/2022/759) on which the scheme is based.
16+
17+
#### Changed
18+
- When consuming libsecp256k1 as a static library on Windows, the user must now define the `SECP256K1_STATIC` macro before including `secp256k1.h`.
19+
1020
## [0.3.2] - 2023-05-13
1121
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`.
