Breaking Changes

●Issue #1

The Comfy API key is removed from the queue API. If you were relying on this for queue management via the API, you will need to update your integration.

Migration Steps

  1. 1
    If using the queue API, update your calls as the Comfy API key has been removed.
  2. 2
    Users experiencing issues with the portable version should update their NVIDIA drivers.
  3. 3
    Users are advised to update their PyTorch versions.

Release Summary
