+## [0.1.0] — 2026-05-03
+
+### Added
+- Initial public release.
+- `compute_dnnu`, `compute_dnnu_from_predictor`, `compute_g2` top-level API.
+- `IntegratorConfig` / `IntegrationResult` data classes.
+- `InterpLogOmegaPCHIP` and `adaptive_simpson_interpolated` lower-level building blocks.
+- Helpers: `maybe_log10f`, `clean_sort_unique`, `simpson_atol_from_dnnu_tol`, `g2_to_dnnu`.
+- Constants module (`Neff0`, `Omega_nh2`, `ln10`).
+- Optional Cobaya adapter `sagenet_dnnu.cobaya_theory.SageNetDnnuTheory` mirroring upstream `SageNetTheoryFinal` behaviour.
+- 22 unit tests covering f-mode detection, input cleaning, tolerance round-trip, PCHIP edge clamping, adaptive Simpson on analytical integrands, end-to-end log-Gaussian validation, and irregular-grid robustness.
+- GitHub Actions CI matrix on Python 3.9–3.12.
+- Two runnable examples in `examples/`.
