+
+### Added
+- Resumable sessions: agents now automatically save state and can resume after interruptions
+- `/resume` command in TUI to resume latest paused/failed session
+- `/resume <session_id>` command to resume specific sessions
+- `/sessions` command to list all sessions for current agent
+- `--resume-session` CLI flag for automatic session resumption on startup
+- `--checkpoint <checkpoint_id>` CLI flag for checkpoint-based recovery
+- Ctrl+Z now immediately pauses execution with full state capture
+- `/pause` command for immediate pause during execution
+- Session state persistence: memory, execution path, node positions, visit counts
+- Unified session storage at `~/.hive/agents/{agent_name}/sessions/`
+- Automatic memory restoration on resume with full conversation history
+
+### Changed
+- TUI quit now pauses execution and saves state instead of cancelling
+- Pause operations now use immediate task cancellation instead of waiting for node boundaries
+- Session cleanup timeout increased from 0.5s to 5s to ensure proper state saving
+- Session status now tracked as: active, paused, completed, failed, cancelled
 
 ### Deprecated
-- N/A
+- Pause nodes (use client-facing EventLoopNodes instead)
+- `request_pause()` method (replaced with immediate task cancellation)
 
 ### Removed
 - N/A
 
-
 ### Fixed
-- tools: Fixed web_scrape tool attempting to parse non-HTML content (PDF, JSON) as HTML (#487)
+- Memory persistence: ExecutionResult.session_state["memory"] now populated at all exit points
+- Resume now starts at correct paused_at node instead of intake node
+- Visit count double-counting on resume (paused node count now properly adjusted)
+- Session selection now picks most recent session instead of oldest
+- Quit state save failures due to insufficient timeout
+- Ctrl+Z pause implementation (was only showing notification without pausing)
+- Empty memory on resume by ensuring session_state["memory"] is properly populated
