Announced on May 19, 2025, the Red5 Cloud v1.9.0 update introduced new features and valuable enhancements. Here is what you need to know about this update.

New Features

• Automatic node scaling can now be triggered by CPU load and memory usage instead of publisher/subscriber count. More accurate and efficient resource scaling based on actual system performance.
