[!NOTE]
Along with this release we also introduce a new command line tool poctl. It is designed specifically for managing Prometheus Operator Custom Resources. This project is currently under active development and fully experimental, so expect breaking changes and rough edges. We encourage you to try it out and provide the feedback.

[!WARNING]
Another notable change is that we have switched the logging framework from go-kit/log to slog which may lead to some differences in the log output.

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.
