WordPress 7.0 "Armstrong", released on 20 May 2026, raised the minimum PHP version from 7.2.24 to 7.4, the first minimum-PHP increase since WordPress 6.6. PHP 8.3 remains the recommended minimum.
Laravel 13 shipped on 17 March 2026 with a first-party AI SDK, JSON:API resources and vector search, and it now requires PHP 8.3 or newer. Laravel 12 stopped receiving bug fixes on 13 August 2026.
PHP 8.1 stopped receiving security fixes on 31 December 2025. As PHP2Shell shows, unsupported branches now get no upstream patches for new vulnerabilities.
Two critical PHP flaws dubbed "PHP2Shell" allow unauthenticated remote code execution on PHP installations serving web requests. Update to PHP 8.5.12, 8.4.27, 8.3.36 or 8.2.35 now; PHP 8.1 and older get no upstream fix.
