Emphasis Weighting Bug Fix
We identified and resolved a bug related to emphasis values between 0 and 1, which made some elements overwhelmingly powerful. After this fix, tag mixing should be much better. In practice, this means that your prompts will need some tweaking if it used emphases between 0 and 1, and generated images will be different as well.
Furthermore, this fix is not intended to replicate the behavior of v4.5; v5 is still a different model with a completely different prompt understanding and behavior. However, it should be more intuitive now.
