Notable changes:

Breaking changes

• The experimental dynamic configuration feature has been removed in favor of Flow mode. (@mattdurham)

• The oracledb integration configuration has removed a redundant field metrics_scrape_interval. Use the scrape_interval parameter of the integration if a custom scrape interval is required. (@schmikei)

• Upgrade the embedded windows_exporter to commit 79781c6. (@jkroepke)

• Prometheus exporters in Flow mode now set the instance label to a value similar to the one they used to have in Static mode ( by default, customized by some integrations). (@jcreixell)

• phlare.scrape and phlare.write have been renamed to pyroscope.scrape and pyroscope.scrape. (@korniltsev)

  • loki.source.api - receive Loki log entries over HTTP (e.g. from other agents). (@thampiotr)
