Hooks Release Notes

Pulse Hooks collect query-level execution details from supported services and publish them to Pulse for observability and analysis. Each release improves compatibility with supported Pulse releases, enhances reliability, introduces new platform support, and expands monitoring capabilities.

You can reach out to Acceldata Support to get the links.
