Notable changes:

Enhancements

• Logs from underlying clustering library memberlist are now surfaced with correct level (@thampiotr)

• Allow setting informer_sync_timeout in prometheus.operator.* components. (@captncraig)

• For sharding targets during clustering, loki.source.podlogs now only takes into account some labels. (@ptodev)

Bugfixes

• Fixed an issue in the pyroscope.write component to prevent TLS connection churn to Pyroscope when the pyroscope.receive_http clients don't request keepalive (@madaraszg-tulip)

• Fixed an issue in the pyroscope.write component with multiple endpoints not working correctly for forwarding profiles from pyroscope.receive_http (@madaraszg-tulip)

• Fixed a few race conditions that could lead to a deadlock when using import statements, which could lead to a memory leak on /metrics endpoint of an Alloy instance. (@thampiotr)

• Fix a race condition where the ui service was dependent on starting after the remotecfg service, which is not guaranteed. (@dehaansa & @erikbaranowski)

• Fixed an issue in the otelcol.exporter.prometheus component that would set series value incorrectly for stale metrics (@YusifAghalar)

• 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 Alloy configuration. (@ptodev)

• Fixed an issue in the pyroscope.write component to allow slashes in application names in the same way it is done in the Pyroscope push API (@marcsanmi)

• Fixed a crash when updating the configuration of remote.http. (@kinolaev)

• Fixed an issue in the otelcol.processor.attribute component where the actions delete and hash could not be used with the pattern argument. (@wildum)

• Fixed an issue in the prometheus.exporter.postgres component that would leak goroutines when the target was not reachable (@dehaansa)
