## Seren Spirits v4.0.52 · HOTFIX
**Persistent Alt1 installation identities**
*26 July 2026*

- Moved installation identity from temporary session-only storage into a persistent per-profile identity map.
- Kept each named RuneScape username on its own stable installation ID while preserving one stable private identity for Anonymous mode.
- Persisted the server-issued Anonymous #**** tag so anonymous contributors keep the same public profile after updates and restarts.
- Shared the current authentication token per profile across Alt1 windows, preventing one window from repeatedly invalidating another window's session.
- Migrated an already-open v4.0.51 session ID or an older saved installation ID into the new persistent profile map on first launch.
- Kept version upgrades as updates to last_app_version and heartbeat fields instead of creating replacement installation rows.
