Patch release 4.55.2!
only affects FA2 generations!
😢 Well sorry everyone, sometimes shit can happen...
4.55.1 was broken because of 🥁 git merge conflict.
I cherry-picked #40002 without having #40029 , thus from ..modeling_flash_attention_utils import prepare_fa_kwargs_from_position_ids is missing, and since this is a slow test, nothing caught it.
Will work to remediate and write the post-mortem when yanking the release.
