0.77.0 / 2024-09-19

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.
