PMD Release Notes

29-November-2024 - 7.8.0

The PMD team is pleased to announce PMD 7.8.0.

This is a minor release.

🚀 New and noteworthy

🌟 New and changed rules

New Rules

• The new Apex rule QueueableWithoutFinalizer detects when the Queueable interface is used but a Finalizer is not attached. Without attaching a Finalizer, there is no way of designing error recovery actions should the Queueable action fail.
