Release 4.2

In this release, the team focused on enhancing monitoring, telemetry, and analytics capabilities of the SDK by improving the integration with Azure App Insights. We have streamlined the integration and default telemetry emitted from the SDK. This include (Waterfall) dialog instrumentation, docs, and examples for querying data, and a PowerBI dashboard. As with any release, we fixed a number of bugs, continue to improve LUIS and QnA integration and further clean our engineering practices. There were additional updates across the other area like Language, Prompt and Dialogs, and Connectors and Adapters.
