on GitHub

1.22.0 (2026-11-12)

⚠ BREAKING CHANGES

• loki.enrich: Removes target_match_label, logs_match_label and metrics_match_label from loki.enrich and prometheus.enrich. The target_to_log_match and target_to_metric_match arguments are now required.
• otelcol.connector: This may render certain configurations invalid. These bad configurations were silently accepted before, but in practice they never caused problems because all connectors currently defined only output one signal type. This issue was surfaced while implementing #7385, which supports more than one output signal.
