   ACK 3977d27baebb7267448e1c4aef1fda4471523831
3. in CHANGELOG.md:15 in 3977d27bae outdated

   11 #### Changed
   12  - The point multiplication algorithm used for ECDH operations (module `ecdh`) was replaced with a slightly faster one.
   13  - 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`.

   15+#### ABI Compatibility
   16+This release is compatible with the ABI of 0.4.0 and 0.3.x.

   Compatibility with 0.3.x is backward-only, right?
