 ## Changelog
 
+### v0.31.3 — Fix FileBrowser integration config persistence (2026-02-25)
+
+#### Fixed
+- FileBrowser integration config (OnlyOffice URL, JWT secret) was lost after `SyncFileBrowserMounts` regenerated `config.yaml` — the async `OnStackStart` re-apply hook failed due to timing issues
+- New `ReapplyConfigForTarget()` method applies integration config synchronously between config generation and container restart, ensuring it survives regen cycles
+
 ### v0.31.2 — Show FileBrowser URL on app card (2026-02-25)
 
 #### Fixed
