Changelog

Sourced from fynch's changelog.

[0.3.2] - 2026-07-07

Changed

• Delegated the optional Gumbel noise and Gumbel-Softmax helpers to drawset.

[0.3.1] - 2026-07-07

Changed

• Switched the optional gumbel feature from kuji to drawset.

[0.3.0] - 2026-07-03

Fixed

• fast_soft_sort now implements Blondel et al. (2020) soft sort as the reference implementation (google-research/fast-soft-sort) defines it, ascending with L2 regularization. The previous construction applied PAVA to sorted - rho with the operand roles inverted, so its outputs matched the reference only on inputs whose sorted values happen to equal their ranks, and its small-regularization limit was rho * strength (tending to zero) instead of the hard-sorted values. Outputs change for effectively all inputs; the parameter is now named regularization_strength to match its role (smaller = closer to hard sort).

Added

• fast_soft_rank: the $O(n \log n)$ Blondel soft rank via the permutahedron projection, ascending with L2 regularization, returning soft ranks in input order. Distinct from the $O(n^2)$ pairwise-sigmoid soft_rank relaxation.
• tests/blondel_reference.rs with a fixture generated from the reference implementation, pinning both functions to externally produced values (inputs with ties and negatives, strengths 0.1 / 1.0 / 10.0), plus a hard-limit rank test independent of the fixture.

[0.2.2] - 2026-06-26

Added

• Optional logp feature implementing logp::BregmanGenerator for Shannon and SquaredL2.

[0.2.1] - 2026-06-26

Added

• sparsemap_explicit and sparsemap_loss_explicit for SparseMAP over a small explicit vertex set.

[0.1.4] - 2026-06-10

Changed

• Bumped innr to 0.4.
• README and CONTRIBUTING polish; publish gated on cargo-semver-checks.
