grafana/alloy v1.14.0

on GitHub

1.14.0 (2026-03-06)

⚠ BREAKING CHANGES

• loki.secretfilter: Some config options are removed entirely:
  • partial_mask (replaced with redact_percent)
  • allowlist (now controlled with custom gitleaks config)
  • enable_entropy
  • include_generic (now controlled with custom gitleaks config)
  • types (now controlled with custom gitleaks config)
• otelcol.receiver.prometheus: otelcol.receiver.prometheus no longer sets start times of OTLP metrics. Grafana Cloud and Mimir do not currently use OTLP metric start times. If you do want your metrics to have them, you can use otelcol.processor.metric_start_time with strategy set to true_reset_point to get the same behaviour.
