QQQ 4.0 established a semantic-versioning contract on Java 21, consolidated middleware packages and aligned the framework libraries through a bill of materials. Its notes identify specific correctness and authorization fixes rather than a blanket claim of safety.
QQQ 4.0 established a semantic-versioning contract on Java 21, consolidated middleware packages and aligned the framework libraries through a bill of materials. Its notes identify specific correctness and authorization fixes rather than a blanket claim of safety.

For maintainers, authorization checks must follow effective inputs and stored ownership, not merely the screen that initiated a request. The release notes document the supported scope and migration details.
