OpenSSL 4.1 Alpha 1 introduces DTLS 1.3 support for improved security and faster handshakes, adds GREASE protocol extension for robust TLS handling, and includes AVX-512 optimizations for cryptographic operations. The release also drops Windows-on-Itanium support and adds initial support for Russia's Elbrus 2000 architecture.
PHP 1.0.0 now runs natively on ESP32 microcontrollers through php-baremetal, which cross-compiles the unmodified Zend engine for bare-metal execution. The project uses the official embed SAPI with minimal build-time patches, enabling full PHP features like OPcache, OpenSSL, SQLite, and WiFi directly on five-dollar chips without transpilation or reimplementation.
