 ## Version History
 
+### v1.3.0 (2026-01-20)
+
+**🚀 Major Feature: OpenCode-Style Session Management**
+
+This release transforms the Sessions view into a clean history browser following OpenCode desktop patterns, removing duplicate UI and implementing seamless Chat view integration.
+
+#### Changes
+
+**✨ New Features**
+- **Project-Based Session Filtering** - Sessions view now filters by current project
+  - Respects `?project=` URL parameter
+  - Only shows sessions from current project directory
+  - Prevents confusion from seeing unrelated sessions
+- **Read-Only Session Browser** - Transformed Sessions view from command interface to history viewer
+  - Removed duplicate command input (use Chat view for active work)
+  - Added "Continue in Chat" action to switch to workspace
+  - Added "Duplicate" action to create new session with same working directory
+  - Added "Terminate" action for running sessions
+- **Enhanced Session Details** - Comprehensive session information display
+  - Session metadata (created, last activity, message count)
+  - Token usage progress bar
+  - Output preview (first 50 entries with scroll)
+  - Clear status badges (🟢 Running vs ⏸️ Stopped/Historical)
+- **Seamless Chat Integration** - Continue sessions from Sessions view
+  - Click "Continue in Chat" to switch views with session loaded
+  - Pending session detection in Chat view
+  - Automatic message restoration (both user and assistant)
+  - Subscribe to live updates for running sessions
+
+**🔧 Improvements**
+- **Relative Time Display** - Shows "5m ago", "2h ago", "3d ago" instead of timestamps
+- **Sorted Session List** - Sessions sorted by last activity (newest first)
+- **Better Empty States** - Helpful messages when no sessions exist
+- **Comprehensive Error Handling** - Clear error messages for 404, 500, etc.
+- **XSS Prevention** - All dynamic content properly escaped
+
+**🐛 Bug Fixes**
+- Fixed session status showing all sessions as "running" regardless of actual state
+- Fixed sessions from other projects appearing in current project view
+- Fixed "sendShellCommand is not defined" error in Full Stack mode
+- Fixed duplicate command input in Sessions view causing confusion
+
+**📝 Technical Details**
+
+- Backend API: `GET /claude/api/claude/sessions?project=<path>` filters by working directory
+- Frontend: `loadSessions()` extracts project from URL and filters session list
+- Frontend: `viewSessionDetails()` shows read-only session information
+- Frontend: `continueSessionInChat()` stores pending session for Chat view pickup
+- Frontend: `loadSessionIntoChat()` restores session messages in Chat view
+- Frontend: `sendShellCommand()` helper for Full Stack mode shell commands
+
+**🔒 Security**
+- All session operations require authentication
+- HTML escaping prevents XSS in session display
+- Session validation prevents unauthorized access
