Release notes for version 0.81.0

Release date: 28 May 2026

Update note 1: defaultRules.create is renamed to defaultRules.enabled; per-group create is renamed to enabled. Old create key is still respected as a fallback if enabled is not set.

Update note 2: defaultRules.additionalGroupByLabels is renamed to defaultRules.extraGroupByLabels. Old additionalGroupByLabels is still respected as a fallback if extraGroupByLabels is not set.

• rename defaultRules.create and per-group create to enabled, with fallback to create for backward compatibility.
• add per-group extraGroupByLabels, that replace defaultRules.extraGroupByLabels (if absent defaults to defaultRules.additionalGroupByLabels). See #2832.
