v1.50.87 — 2026-08-18¶
- feat(alerting): Granular alert settings — queue depth, quarantine depth, certificate expiry warning, peer heartbeat timeout, disk usage threshold, and cooldown duration are now configurable in the alert settings UI (Security → Settings) instead of being hardcoded; values are persisted in mail_config and applied on the next alerting tick (1.50.87)
