This maintenance release is available on the stable channel for appliances on the 0.8.6 line.
This release consolidates the validation work from the 0.8.6.6-rc* release candidates into a single stable build. It is a maintenance release focused on database upgrade safety, management API reliability, policy reporting, licensing, and Cisco integration tooling.
Enhancement: Optional org-level diagnostics: appliances can forward backend error telemetry and alarm-lifecycle events to a PostHog project for support correlation. Off by default; opt-in per org.
Fix: Added missing stable database migrations for Grafana settings, alarm preferences, token sessions, and per-user alarm sound settings. This fixes upgrade/runtime crashes caused by missing database fields.
Fix: Several management API endpoints now return proper 404 or 422 responses instead of 500 errors for edge-case requests, including rules and policies, TDoS history, webhook logs, phone statistics, report queries, and CallManager discovery.
Fix: Policy history dashboards and reputation reporting paths refresh correctly after fresh install or upgrade.
Fix: Active product licenses are preserved across transient license-server validation failures instead of briefly dropping to an unlicensed state.
Fix: Cisco integration workflows are more robust: AXL/JTAPI errors return clean payloads, JTAPI BIB/greeting rollback and audit metadata are safer, runtime-created lab CallManagers surface inventory correctly, and SFTP session ownership is preserved.
