StackState SaaS release notes

Note that the release notes may include details of functionality that is currently only available in the StackState Self-Hosted product.
StackState v4.6.x
v4.6.0 (04-03-2022)
The StackState v4.6 release brings powerful new capabilities:
Important improvements in topology visualization to accelerate troubleshooting.
Support for OpenTelemetry traces, specifically for serverless AWS Lambda applications built with Node.js. This new low-latency data requires no integration, and will immediately enrich your topology with additional relationships and telemetry.
Expanded Autonomous Anomaly Detection capabilities to automatically analyze the golden signals of throughput, latency and error rate. Automatic health checks can then run on this data and alert you as soon as anomalies are found. This will help you to get to the root cause of incidents more quickly and proactively prevent problems before they occur.
Details of the included improvements and bug fixes can be found below.
