I just released v0.6 of [fips203ipd][fips203ipd-git].
[fips203ipd][fips203ipd-git] is an embeddable, dependency-free,
[MIT-0][] licensed, [C11][] implementation of the [FIPS 203 initial
public draft (IPD)][fips203ipd] with scalar, [AVX-512][], and [Neon][]
backends. The final version of [FIPS 203][fips203ipd] will become
ML-KEM, [NIST's][nist] standarized post-quantum [key encapsulation
mechanism (KEM)][kem].
[Git Repository][fips203ipd-git], [API Documentation][fips203ipd-api-docs],
[Original Announcement][fips203ipd-announce], [pqc-forum Announcement][pqc-forum-announce]
### Changes in v0.6
- Add [Neon][] backend
- Add MacOS support to test suite (thanks [Rod][rod-chapman]!)
- Add backend auto-detection, `BACKEND` command-line build parameter,
and `fips203ipd_backend()` function
- Add [Raspberry Pi 5 (Cortex-A76)][pi5] benchmarks
- Add "Backends" documentation section with brief notes about each backend
### Benchmarks
Here are median cycle count as measured by the included `bench` tool for
each parameter set, function, compiler, and backend from several of my
systems.
For context, the results below are competitive with the [eBATS][]
results ([kyber512][], [kyber768][], [kyber1024][]), although the
comparison is inexact because the results were measured with different
tools and because [Kyber][] and ML-KEM differ slightly.

**Update (2024-05-16):** Added cycle counts for scalar backend (clang
and gcc), added bar charts, added downloadable [CSVs][csv]. The
[CSVs][csv] and [SVGs][svg] generated by the [Python][] scripts in the
[`scripts/bench-chart/` directory of the Git repository][bench-chart].
