MeshMonitor v4.0.1

Hotfix release for v4.0.0. Addresses critical migration and stability issues encountered during 3.12 → 4.0 upgrades, plus several multi-source bugs reported by early upgraders. The server now survives SIGTERM and DB-not-ready conditions during long migrations, preserves legacy telemetry and neighbor data when migrating from 3.12, and correctly maps existing 3.x data structures into the new multi-source schema. Multi-source operation is more forgiving: virtual node ports may now equal a source TCP port, and the auto-favorite warning is correctly scoped to the active source. Also includes Node base image security upgrades and a settings hydration fix.

Bug Fixes

• Migrations: preserve legacy telemetry & neighbor data on 3.12 → 4.0 upgrade (#2827)
• Migrations: support 4.0 multi-source data structures in migrate-db tool (#2829)
• Server: survive SIGTERM and DB-not-ready during long migrations (#2825)
• Auto-favorite: scope status fetch to active source (#2828, fixes #2826)
• Sources: allow virtualNode.port to equal source TCP port (#2823, fixes #2823)
• Settings: stop re-POSTing tracerouteIntervalMinutes on hydration (#2822)

Security

• Node base image: 24.14.0 → 24.14.1 → 24.15.0 (Alpine 3.22) (#2820, #2821)

Issues Resolved

• #2826 — Autofavorite displays warning even when node is client_base
• #2823 — Virtual Node port cannot equal the source TCP port

Upgrade Notes

If you are upgrading from 3.12 directly to 4.0, this release is strongly recommended — it preserves legacy telemetry and neighbor data that earlier 4.0.0 builds could lose during the migration. Long migrations are now resilient to SIGTERM and database-not-ready races, so container restarts during the upgrade no longer corrupt state.
