 > **Stable line (2026)** — First maintained **stable** release **[v1.0.0](https://github.com/PurHur/php-compiler/releases/tag/v1.0.0)**; **v1.1.0** prep adds M5 fast-path stability, enum/property-hook parity, `preg_match` JIT, `spl_autoload*`, and php-in-PHP JIT helpers. Demo-ready VM + AOT for a **web-capable PHP subset**, reference examples **000–009**, and an experimental **self-host** path. Not full Zend PHP compatibility — see [what’s missing](https://purhur.github.io/php-compiler/docs/pages/missing-implementation.html).
