Panel Backend
v1.0.509
Secondary/Cluster DNS support, one-click Docker forum fixes, and several stability fixes.
New Feature
1- New: Secondary/Cluster DNS — authorise secondary nameservers and run a server in secondary mode to automatically mirror a primary server zones (AXFR + NOTIFY) for DNS redundancy. Managed in Panel Settings -> DNS. Single-server setups are completely unaffected.
Improvement
1- Docker template fixes: named-volume deletion, stale link URL warnings after linking, and improved subdomain link naming/matching.
Bug Fixes
8- One-click Docker forums (Discourse, Lemmy, Flarum) now install and reach the admin/setup screen cleanly: fixed a setup-page hang, database authentication when using {{env:}} placeholders, single-domain reverse proxying, mail driver defaults, and memory/concurrency tuning.
- The impersonation banner no longer incorrectly shows viewing as a user after an admin returns to their own root session.
- SSL renewal is no longer attempted on suspended domains or the subdomains of a suspended domain.
- Fixed a race condition when a user is deleted and immediately recreated, and a bug where a domain PATCH could silently drop fields that were not included in the request.
- External API domain deletion now runs the full cleanup chain instead of a partial one.
- Changing a user plan now applies the new disk quota immediately; migration deep-scan now correctly counts mailbox size.
- Isolation self-heals stale UID records without killing the affected user session (SH-095).
- Server overview now reports real swap, TCP connection, open file, fork and context-switch metrics instead of placeholders.
