0.72.0 / 2024-03-04

In this release, we want to highlight the addition of ScrapeClasses.

ScrapeClasses is an experimental feature that allows declaring multiple scrape configurations in the Prometheus/PrometheusAgent objects that can be consumed by selected scrape-related resources, like ScrapeConfig, ServiceMonitor, PodMonitor and Probes. Initial support only allows the declaration of TLS configuration, but we plan to extend ScrapeClasses with more options in the future, e.g. Authorization, relabelings and scrape protocols.
