• Image-heavy turns are processed up to 3.3× faster, and session resumes are about 18% faster.
• The model catalog now refreshes automatically.
• A new /fork command forks a conversation.
• libfx handles images better and recovers from crashes better; the release also has bug fixes and security improvements.
