OxiProj 0.1.5 is a correctness release for the EPSG authority (proj.db) coordinate path: twelve defects — from a 3.28x-oversized ellipsoid to a 380 m operation-selection miss — found and fixed against the Homebrew PROJ 9.7.0 oracle, every number measured, not derived. 2,855 tests passing, 0 failing.
OxiProj 0.1.4 is a maintenance release: two Python-packaging fixes (missing LICENSE files in the maturin sdist, PyPI trusted publishing), a corrected cs2cs Quick Start example, ecosystem dependency bumps across seven COOLJAPAN crates, and a documentation-accuracy pass that corrects the README's own parity-corpus numbers. No public API changes, no behavior changes, no source changes to any library crate.
OxiProj 0.1.3 is a maintenance release: no public API changes, no behavior changes. It pulls forward real hardening from five upstream COOLJAPAN crates — a 44-agent HDF5 interop audit, a CUDA async-copy race-condition fix, faster zero-copy DEFLATE decoding, and OxiZ's soundness sweep — plus a `wide` 1.6 deprecation cleanup in the SIMD scalar power path. Still 100% Pure Rust, no C, no FFI.
OxiProj 0.1.2 is a hardening/correctness release for the Pure-Rust PROJ replacement: automatic epoch-aware datum pathfinding, exact-autodiff Tissot distortion reachable from the public engine API, guaranteed-bounds interval-arithmetic transforms, SIMD batch lane-correctness fixes, and an SQL-injection fix — still no C, no FFI.
Two days after its debut, OxiProj 0.1.1 adds Python (PyO3) and WASM bindings, Tissot indicatrix and covariance/autodiff analysis, SIMD + rayon + oxicuda GPU reprojection, and geo-types/geozero/GeoParquet interop. Still a Pure-Rust PROJ replacement — no C, no FFI.
OxiProj 0.1.0 debuts: a 100% Pure-Rust replacement for proj-sys / PROJ. A near-complete port of PROJ 9.8.0 with ~197 projections, full Karney geodesics, ISO-19111 CRS, the EPSG proj.db via oxisql-sqlite-compat, and 1345 passing tests — no C, no FFI.
