Notable changes:

Bugfixes

• loki.source.podlogs: Fixed a bug which prevented clustering from working and caused duplicate logs to be sent.
  The bug only happened when no selector or namespace_selector blocks were specified in the Agent configuration. (@ptodev)

• pyroscope.scrape no longer tries to scrape endpoints which are not active targets anymore. (@wildum @mattdurham @dehaansa @ptodev)

Enhancements

  Modern container runtimes allow binding to unprivileged ports as non-root. (@ptodev)
