+## [0.3.2] - 2025-12-12
+
+### Added
+- **Progressive Web App (PWA) Mobile Optimization**: Complete mobile-first redesign for field deployment usage
+  - **Responsive Navigation**: Hamburger menu with slide-in sidebar for mobile, always-visible sidebar for desktop
+  - **Bottom Navigation Bar**: Quick access to Dashboard, Roster, Add Unit, and Settings (mobile only)
+  - **Mobile Card View**: Compact card layout for roster units with status dots, location, and project ID
+  - **Tap-to-Navigate**: Location addresses and coordinates are clickable and open in user's default navigation app (Google Maps, Apple Maps, Waze, etc.)
+  - **Unit Detail Modal**: Bottom sheet modal showing full unit details with edit capabilities (tap any unit card to open)
+  - **Touch Optimization**: 44x44px minimum button targets following iOS/Android accessibility guidelines
+  - **Service Worker**: Network-first caching strategy for offline-capable operation
+  - **IndexedDB Storage**: Offline data persistence for unit information and pending edits
+  - **Background Sync**: Queues edits made while offline and syncs automatically when connection returns
+  - **Offline Indicator**: Visual banner showing offline status with manual sync button
+  - **PWA Manifest**: Installable as a standalone app on mobile devices with custom icons
+  - **Hard Reload Button**: "Clear Cache & Reload" utility in sidebar menu to force fresh JavaScript/CSS
+- **Mobile-Specific Files**:
+  - `backend/static/mobile.css` - Mobile UI styles, hamburger menu, bottom nav, cards, modals
+  - `backend/static/mobile.js` - Mobile interactions, offline sync, modal management
+  - `backend/static/sw.js` - Service worker for PWA functionality
+  - `backend/static/offline-db.js` - IndexedDB wrapper for offline storage
+  - `backend/static/manifest.json` - PWA configuration
+  - `backend/static/icons/` - 8 PWA icon sizes (72px-512px)
+
+### Changed
+- **Dashboard Alerts**: Only show Missing units in notifications (Pending units no longer appear in alerts)
+- **Roster Template**: Mobile card view shows status from server-side render instead of fetching separately
+- **Mobile Status Display**: Benched units show "Benched" label instead of "Unknown" or "N/A"
+- **Base Template**: Added cache-busting query parameters to JavaScript files (e.g., `mobile.js?v=0.3.2`)
+- **Sidebar Menu**: Added utility section with "Toggle theme" and "Clear Cache & Reload" buttons
+
+### Fixed
+- **Modal Status Display**: Fixed unit detail modal showing "Unknown" status by passing status data from card to modal
+- **Mobile Card Status**: Fixed grey dot with "Unknown" label for benched units - now properly shows deployment state
+- **Status Data Passing**: Roster cards now pass status and age to modal via function parameters and global status map
+- **Service Worker Caching**: Aggressive browser caching issue resolved with version query parameters and hard reload function
+
+### Technical Details
+- Mobile breakpoint at 768px (`md:` prefix in TailwindCSS)
+- PWA installable via Add to Home Screen on iOS/Android
+- Service worker caches all static assets with network-first strategy
+- Google Maps search API used for universal navigation links (works across all map apps)
+- Status map stored in `window.rosterStatusMap` from server-side rendered data
+- Hard reload function clears service worker caches, unregisters workers, and deletes IndexedDB
+
+## [0.3.1] - 2025-12-12
+
+### Fixed
+- **Dashboard Notifications**: Removed Pending units from alert list - only Missing units now trigger notifications
+- **Status Dots**: Verified deployed units display correct status dots (OK=green, Pending=yellow, Missing=red) in both active and benched tables
+- **Mobile Card View**: Fixed roster cards showing "Unknown" status by using `.get()` with defaults in backend routes
+- **Backend Status Handling**: Added default values for status, age, last_seen fields to prevent KeyError exceptions
+
+### Changed
+- Backend roster partial routes (`/partials/roster-deployed`, `/partials/roster-benched`) now use `.get()` method with sensible defaults
+- Deployed units default to "Unknown" status when data unavailable
+- Benched units default to "N/A" status when data unavailable
