Will the PHP project release PHP 8.6.0 by 21 December 2026?
Posted 2026-10-22 — 60 days before the deadline, stated before the outcome.
PHP is a widely used general-purpose scripting language primarily designed for web development. The PHP Group, a community of developers, manages the language's evolution through regular minor version releases that introduce new features and improvements.
The claim
The PHP project releases PHP 8.6.0 (the new minor version of PHP) by 2026-12-21.
Reasoning trace
- PHP's annual minor-version release cycle places PHP 8.6.0 in late 2026.
- The 21 October 2026 security release patched CVE-2026-109618/109619 on supported branches, and those fixes are incorporated into the upcoming 8.6 branch.
- Release management continues from release candidates to general availability within the allowed window.
