+## [0.9.4] - 2026-04-06
+
+### Added
+- **Modular Project Types**: Projects now support optional modules (Sound Monitoring, Vibration Monitoring) selectable at creation time. The project header and dashboard dynamically show/hide tabs and actions based on which modules are enabled, and modules can be added or removed after creation.
+- **Deleted Project Management**: Settings page now includes a section for soft-deleted projects with options to restore or permanently delete each one. Deleted projects load automatically when the Data tab is opened.
+
+### Changed
+- **Swap Modal Search**: The unit/modem swap modal on vibration location detail pages now includes live search filtering for both seismographs and modems, making it easier to find the right unit in large fleets.
+
+### Fixed
+- **Roster Auto-Refresh No Longer Disrupts Scroll/Sort**: The roster page's 30-second background refresh now updates status, age, and last-seen values in-place via a lightweight JSON poll instead of replacing the entire table HTML. Sort order, scroll position, and active filters are all preserved across refreshes.
