Unreleased

1.1.0 - 2026-07-08

Added

• NestedKriging: divide-and-conquer Gaussian process for large designs — partition of (X, y) into groups with one Kriging submodel each, unified hyperparameters, and aggregated predictions (PoE / gPoE / BCM / rBCM and the optimal nested-kriging NK aggregation), with Python/R/Octave/Matlab/Julia bindings (#317).
• Vecchia approximated log-likelihood objective VLL(m), with local prediction and a factorization-free "light" mode (#318).

Fixed

• Fork-after-threads deadlock in forked child processes (#319).
• Windows CI on the windows-2025-vs2026 runner image: CMake pinned to the version providing the "Visual Studio 18 2026" generator, and Octave/conda setup (#320).
• Thread Sanitizer job: removed false-positive data races caused by GCC's uninstrumented OpenMP runtime (libgomp) (#320).
• Constructor argument consistency across bindings: R Kriging now accepts objective="VLL(m)" and the "quadratic" trend, with noise as the last argument (aligned with Python/WarpKriging); Julia Kriging/NestedKriging accept a parameters dict like the other classes (#323).

Documentation

• Documentation, licensing and metadata review: fixed stale dependency and architecture docs, added scientific and input-warping references, added CITATION.cff, NOTICE and this changelog, and README features/license/ citation sections (#321).
