PHP 8.5.3 and PHP 8.4.18 have been released, addressing various bugs including garbage collector leaks, memory leaks, and issues with the DOM class. While both versions share many core fixes, PHP 8.5.3 introduces additional safeguards for JIT-enabled Opcache systems and prevents certain cloning and comparison behaviors for internal enums. Updates in both releases include Timelib version 2022.16 and improvements in multibyte string reliability, ensuring better handling of certain errors. Sites experiencing crashes may benefit from upgrading to PHP 8.5.3, whereas those stable on 8.4.18 may choose to upgrade solely for the added protections in the newer version

PHP 8.5.3 and PHP 8.4.18 have been released with bug fixes for issues such as garbage collector leaks, null dereferences, and memory leaks. The two versions share most core patches, but PHP 8.5.3 adds extra safeguards for systems using JIT-enabled Opcache and prevents internal enums from being cloned or compared in certain ways.
