PHP 8.6.0 Beta 3 has been released, featuring automatic closure optimizations that enhance performance through stateless closure caching and static inference. This update also introduces several quality-of-life improvements, including a new clamp() function, the #[\Override] attribute for constants, and stricter error handling for streams. Additionally, PHP's bundled Oniguruma regex engine has reached its end-of-life, marking a significant infrastructure change, while the minimum requirements now include autoconf 2.71 and newer database servers. Looking ahead, the PHP team is exploring ambitious features for version 8.7, such as primary constructors and native JSX-style markup syntax, aimed at improving developer ergonomics
