 - Setting timeouts in the HTTP client used by the IBM MQ scaler ([#1758](https://github.com/kedacore/keda/pull/1758))
 - Fix cleanup of removed triggers ([#1768](https://github.com/kedacore/keda/pull/1768))
 - Eventhub Scaler: Add trigger parameter `checkpointStrategy` to support more language-specific checkpoints ([#1621](https://github.com/kedacore/keda/pull/1621))
+- Fix Azure Blob scaler when using multiple triggers with the same `blobContainerName` and added a optional `metricName` field ([#1816](https://github.com/kedacore/keda/pull/1816))
