Changelog

This file documents notable changes to the project.

Jan-2026

Complete rewrite --- lot of the changes were inspired by the Rust version of the library: gf2_rs.
Renamed the library from bit to gf2 (someone had already taken the name bit on crates.io).
Classes and functions have been moved into the gf2 namespace.
Added gf2::BitStore as a common concept interface for the vector-like classes:
- gf2::BitArray for fixed-size vectors of bits (backed by std::array).
- gf2::BitVector for dynamically-sized vectors of bits (backed by std::vector).
- gf2::BitSpan for non-owning views into any bit-store.
Added iterators for bits, set bits, unset bits, and store words for all bit-stores.
gf2::BitRef allows references to individual bits.
gf2::BitMatrix and associated algorithms for matrices over GF(2).
gf2::BitPolynomial and associated algorithms for polynomials over GF(2).
Documentation now uses Doxygen and published via GitHub Actions to GitHub Pages.
The project uses Doxytest to extract and run tests from code examples in header comments.

Moved the repo to github.
The documentation/site-builder was moved from AsciiDoc/Antora to Markdown/Quarto.
Added the bit::polynomial class for polynomials over GF(2).
Incorporated various fixes and speed-ups from @jason.

The library started as GF2 which evolved to the bit library hosted on GitLab.
