AWS IoT TwinMaker introduces new features to improve the performance of data panels powered by the TwinMaker Grafana Plugin. For a complete list of features, see the changelog on AWS IoT TwinMaker App in Grafana.
A few key features included in this new version are:

Customers can now define the maximum number of alarms that are retrieved by the Get Alarms Query, which provides a way to configure payload size.
The Get Property Value History by Entity query and Get Property Value History by Component Type query now support template variables such as propertyName. This enables developers to create dynamic time-series data panels that will display different properties/metrics based on selected entities.
