Changes

Mitigate CVE-2026-43284 and CVE-2026-43500

This release includes mitigation for CVE-2026-43284 and CVE-2026-43500, aka “Dirty Frag” .

Relay proxy dropped connection fix

Improvements are made in error recovery for the relay proxy when clients close connections. Previously, when a client closed a connection, it could result in connection in an inconsistent state. Then subsequent requests could attempt to use the connection and fail because the state maintained by the proxy server was not consistent with the state of the connection in PHP-FPM. This change causes a FastCGI abort to be used when a client terminates a connection early, releasing PHP-FPM resources as early as possible and preventing connection reuse.

New “Standard Magento” stack

This release introduces a new web-server-v4 image family. Note that this family is not compatible with images in the invoker based web-server and they must not be considered interchangeable.
