SciRS2 0.5.1 is a correctness and Pure-Rust hardening release: exact autograd gradients for matrix functions (Sylvester / Daleckii–Krein / reduced-SVD VJP), a restored CoreError #[non_exhaustive] contract, honest GPU/CUDA reporting, public Zarr v2/v3, and the removal of the C/MPFR rug, C rusqlite, and tokenizers dependencies. 36,606 tests, zero warnings — the sovereign scientific-computing layer of the COOLJAPAN ecosystem.
OxiArc 0.3.3 is a correctness release: Brotli now round-trips high-entropy and incompressible data byte-for-byte across all quality levels 1–11. A package-merge Huffman code generator and an extended insert-length table fix two long-standing encoder bugs. Pure Rust, on-the-wire compatible, 1,679 tests passing.
