Codex History Sync Tool v1.4

v1.4

This release focuses on making the macOS history sync flow safer and easier to install.

Added

• DMG installer package for direct macOS installation.
• Advanced Restart Codex and Sync Threads action for CC Switch or account/API switching workflows.
• UI guidance that marks the restart sync action as an advanced feature and recommends disabling automatic launch sync before using it.

Improved

• One-click sync now refreshes status first and only runs when movable threads exist.
• Automatic Codex launch sync now uses the same movable_threads rule, so model-only mismatches are synchronized too.
• Restart sync now runs in a background thread and reopens Codex via macOS open, avoiding UI freezes when Codex closes or restarts slowly.
• Advanced help text now wraps properly in the app window.

Validation

• python3 -m py_compile launch_ui_mac.py sync_backend.py auto_sync_watcher.py
• python3 launch_ui_mac.py --smoke-test
• hdiutil verify dist/Codex-History-Sync-Tool-v1.4.dmg
