0.3.0-dev

First developer preview of the v0.3 rewrite

This is the first dev build of the full PyLua v0.3 rewrite: a Python 3.12-focused interpreter implemented in Luau with a CPython-style pipeline (Lexer → Parser → AST → Compiler → Bytecode → VM). It’s a ground-up redesign for correctness, maintainability, and a Lupa-inspired API (Python-in-Luau). Expect rough edges and behavior may change before a stable release.
