PHP 8.6.0 RC6 has been released as the final release candidate just nine days before the stable version is scheduled for launch on November 19, 2026. This release includes four targeted fixes related to core ABI padding, a date library update, fileinfo regressions, and a memory safety issue in streams, but no new features. Developers are encouraged to test RC6 in non-production environments and report any issues, while avoiding deployment in production until the stable release. The upcoming stable version is expected to introduce several enhancements, including partial function application, a native polling API, and a new range-limiting function

The changes span Core ABI padding, a timelib date bump, libmagic Fileinfo regressions, and a Streams use-after-free. Test it in non-production environments now, but hold off on production until GA ships on 19 November.
