SciRS2 0.4.4 Released — A Pure-Rust Computer Algebra System Lands in scirs2-symbolic

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.

OxigenAI 0.1.0 Released — Japan's Government Legal AI, Rebuilt in Pure Rust with Formal Verification

OxigenAI is a Pure Rust GovTech reimplementation of the Digital Agency's government legal-AI system (源内 / GenAI). It keeps the familiar law-report API but adds OxiZ SMT contradiction detection and Legalis-RS LegalResult<T> outcome classification — turning a probabilistic LLM+RAG service into a verifiable computational-law platform.

OxiLean 0.1.2 Released — Real SMT Solving, a Full WASM Interpreter, and Keccak-Correct EVM Codegen

OxiLean 0.1.2 lands real SMT solving via OxiZ, a complete 157-instruction WebAssembly bytecode interpreter wired to the real kernel/parse/elab pipeline, keccak256-correct EVM/Solidity ABI selectors, real Gröbner-basis reduction for polyrith, and 33,091 passing tests — all in a Pure Rust theorem prover.

Legalis-RS 0.1.4 Released — One Engine, 23 Jurisdictions: Proof That Law Is Universal Computation

Pure-Rust legal statute engine. 0.1.4 adds 5 new jurisdictions (Korea, Mexico, Malaysia, Russia, Saudi Arabia) for 23 total, 6 production examples proving one generic engine handles Civil/Common/Supranational law, real-time self-healing verification on the OxiZ SMT solver, and auto-generated TypeScript/Python SDKs. 14,705 tests passing.
