package modelkit

0.2.1 (2026-08-11)

• Restore package builds on OCaml 5.5 by making typed target accessor specializations explicit.
• Test OCaml 5.5 on Linux, macOS, and Windows in addition to the existing OCaml 5.2 and 5.3 matrix.

0.2.0 (2026-08-10)

• Add immutable float64 vectors and matrices, row views, typed targets, feature schemas, sample weights, groups, and validation errors over portable Bigarray storage.
• Define common contracts for immutable specifications, fitted estimators, classifiers, regressors, transformers, scorers, splitters, execution, random-number generation, and numerical backends.
• Add deterministic seeds and random streams, stable sequential execution, and a portable reference backend with cancellation-safe reductions and matrix-vector kernels.
• Establish unit, property, metamorphic, mdx, public API compatibility, sklearn fixture, and reusable numerical-backend conformance tests.
• Add pinned development-only Python tooling and committed metadata for reproducible sklearn reference fixtures and comparative benchmark collection without introducing a runtime Python dependency.
• Verify build, tests, package installation targets, and odoc generation on Linux x86-64, macOS arm64, and Windows x86-64 with OCaml 5.2 and 5.3 in GitHub Actions.

0.1.0 (2026-08-04)

• Establish the initial ModelKit package with an OCaml 5.2 compiler floor and Apache-2.0 licensing.
• Add the portable library skeleton and reserved package boundaries for optional adapters and accelerated backends.
• Add the Dune workspace, generated odoc documentation, formatting checks, and platform-specific opam lock workflow.
• Document project governance, support, and maintenance policies.
