SciRS2 0.6.1 replaces placeholder and silently-wrong code paths with real implementations: genuine model-serving codegen, a critical DLPack SIGBUS fix, honest GPU-dispatch and hardware-detection reporting, and a symbolic-engine soundness fix — plus F-distribution ppf, spatial hamming distance, and new finance facades. Pure Rust, Apache-2.0.
SciRS2 0.6.0 introduces the pure-Rust oxicuda-* CUDA stack as a direct, per-crate NVIDIA performance backend and decentralizes GPU out of scirs2-core. Ten crates — fft, symbolic, interpolate, special, stats, graph, linalg, optimize, datasets, and vision — gain an off-by-default, runtime-probed, f64-native cuda feature standing alongside the existing wgpu/WebGPU portability path, now standardized under one wgpu feature name across the ecosystem. A default build still compiles zero oxicuda. Pure Rust, Apache-2.0.
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.
SciRS2 0.5.0 brings real pure-Rust wgpu/WebGPU acceleration — GpuNdarray, GPU graph algorithms, GPU optimizers (L-BFGS/CG/Newton), GPU RBF interpolation — plus correct Pantelides DAE index reduction, high-order SDE Lévy-area, Hilbert curves, and a maturing symbolic CAS. The NumPy/SciPy/scikit-learn replacement, in pure Rust.
SciRS2 0.4.4 turns scirs2-symbolic into a full computer algebra system — EML-IR-native canonical form, real OxiZ SMT verification, Cranelift JIT, symbolic regression, and LaTeX export. A pure-Rust SymPy/Mathematica alternative on top of the NumPy/SciPy replacement.
SciRS2 is the pure-Rust SciPy/scikit-learn replacement. 0.4.3 introduces the brand-new scirs2-symbolic crate (symbolic differentiation + algebraic simplification), full WASM TypeScript declarations & React hooks, an inverse wavelet packet transform, and modernized dependencies — 34,883 tests, 2.94M lines, 32 crates, zero warnings.
SciRS2 0.4.2 — pure-Rust SciPy/NumPy/scikit-learn replacement, 2.94M SLoC, 27,632 tests, 29 crates. This release adds Neural Architecture Search, CMA-ES, Mamba SSM, async/unified GPU memory, H-matrix compression, streaming FFT, DLPack zero-copy, and Apache Iceberg/DataFusion IO. No C/Fortran.

SciPy-compatible scientific computing and AI framework in 100% Pure Rust. 2.91M SLoC, 29 crates, 25,800+ tests. Flash Attention 2, LoRA/DoRA/GPTQ, ONNX export, GPU PDE/FFT/SpMV, Temporal GNNs, NeRF/instant-NGP, WebGPU backend, Delta Lake / Kafka I/O and more. 10–100× faster, zero system deps. The sovereign scientific computing and AI foundation for the entire COOLJAPAN ecosystem (now 21M+ SLoC total).
SciRS2 0.3.4 is the pure-Rust SciPy/NumPy/scikit-learn replacement: 2.59M SLoC, 19,700+ tests, 29 workspace crates. This release upgrades OxiARC to 0.2.5 and purges the last C-library (GMP/MPFR) and the zip crate from the dependency tree for a leaner, smaller-attack-surface, 100% Pure Rust supply chain.
SciRS2 is a pure-Rust SciPy/NumPy/scikit-learn replacement — 2.59M SLoC, 19,700+ tests, 29 crates, no C or Fortran. The 0.3.2 patch upgrades the Python bindings to pyo3 0.28.2 (Python::attach) for free-threaded CPython 3.13, plus benchmark modernization with std::hint::black_box.
2.59 million lines of pure Rust. SciPy-compatible APIs, 10-100× faster with SIMD, no C/Fortran deps, 29 crates, 19,700+ tests, Python + WASM + no_std. The sovereign scientific computing and AI foundation for the entire COOLJAPAN ecosystem.
Production-grade BLAS and LAPACK entirely in Rust. Up to 172% of OpenBLAS performance on Apple M3, full sparse solvers, f128 precision, RuntimeAutoTuner, no_std support. The sovereign mathematical foundation for SciRS2 and the entire COOLJAPAN scientific computing stack.
2.59M SLoC. 29 crates. 19,700+ tests. 10–100x faster than NumPy/SciPy. The complete sovereign scientific computing platform is here — no C, no Fortran, no Python.
OxiBLAS 0.2.0 is a major step up: cache-oblivious recursive and parallel factorizations, batched BLAS, runtime auto-tuning, multifrontal sparse solvers, mixed-precision refinement, NUMA-aware allocation, and no_std support — with the Fortran FFI retired in favor of a fully pure Rust workspace.
TenRSo is a production-grade, Rust-native tensor computing stack — generalized contraction plus a cost-based planner, sparse/low-rank mixed execution, CP/Tucker/TT decompositions, and out-of-core processing. This release candidate adds masked einsum, executor element-wise ops, TT-SVD gradients, and CP regularization as we approach our first stable cut.
SciRS2 is a pure-Rust SciPy/NumPy/scikit-learn replacement, and 0.3.0 is the biggest release yet — transformers, GNNs, diffusion, MoE/RLHF, Gaussian processes, MCMC, survival analysis, radar/compressed sensing, LOBPCG/AMG, plus new Julia and Python bindings. 19,644 tests, ~2.59M lines of Rust. No C, no Fortran.
SciRS2 is the pure-Rust SciPy/NumPy replacement. 0.2.0 restores the entire workspace to zero compile errors, makes Pure Rust OxiFFT the default FFT backend (rustfft now optional), rebuilds the neural stack, and ships the first WebAssembly bindings. ~11,400 tests, zero warnings. No C. No Fortran.
Pure-Rust SciPy/NumPy replacement. 0.1.5 is a polish release — workspace version alignment, strict scirs2-core import policy, correct GPU feature wiring, and a leaner dependency tree. OxiFFT stays the Pure Rust default. No C, no Fortran, no system dependencies.
