Version Information

Current Version: 1.3.0

Hash-based deduplication fix: Unique hash now based on timestamp + token counts (not User/Model), preventing duplicates when importing CSVs without User column
Database migration system: Versioned migrations that run automatically on startup; migration 1.1.0 recalculates hashes for existing data
Import batch deletion: Delete import batches from Settings → Import history; removes all associated events and sessions
Improved quit functionality: Floating window Quit button kills ALL running instances; terminal command quit-ai-usage available
Port changed to 5001: Avoids conflict with macOS Control Center (which uses port 5000)
Orphaned session cleanup: Automatically removes sessions with no events after batch deletion

Settings UI: Database path, session gap, SCM path, Downloads lookback; persisted across restarts.
Project groups: Create groups, assign projects; filter sessions by group.
Import from Downloads and import history in Settings.
Session detail: Per-event project edit and unlink; Re-detect Sessions button.
Standalone app: DB path from config file; floating window (Open in Browser, Settings, Quit).
Generic repo: No personal paths/usernames; plist uses REPLACE_ME_PROJECT_DIR.

Model info in sessions, project edit/delete, SCM path UI, empty project filtering, multi-computer and iCloud DB support, timezone handling, recursive scanning, file mtime detection.
