TRANSFORMERS FIXES RECURRENT MASKING BUG; MOON-IDE KILLS PAIRING WINDOW

By RepoJournal · Filed · About Hugging Face

A critical padding mask bug in transformers is now fixed for chunked prefill and cache continuation, while moon-ide removes dead startup ceremony and hardens the remote bridge client.

Transformers shipped two critical fixes this cycle. First, `create_recurrent_attention_mask` was returning `None` during multi-token forwards from cache, meaning chunked prefill and cache continuation never zeroed padding in the linear-attention state [1]. Second, distributed training infrastructure landed with DistributedMixin and a new distributed/utils.py module, laying groundwork for FSDP orchestration without breaking the from_pretrained API [2]. Additional model fixes address yarn `mscale_all_dim` across DeepSeek v2 and Mistral 4 [3], and Cosmos 3 Edge patch packing [4]. Over in moon-ide, the startup pairing window is gone: since enrolled IDEs mint codes on demand, the printed QR at serve startup was dead surface [5]. Three fixes landed for the outbound relay client: rustls provider initialization at startup, clean reconnection handling, and silent task kills [6]. The relay hub is now production-deployed on bridge.coyo.dev behind nginx with two new serve flags: --no-idle-exit (to keep the standing relay alive) and --advertise-url (to fix pairing payload routing) [7]. Diffusers deprecated `torch_dtype` in favor of `dtype` following transformers convention [8], and removed the experimental API warning from LoRA modules [9]. The optimum-intel OpenVINO pipeline added image-to-video support for LTX-Video [10]. Funes dropped its automated-first-index guard since cold stores now fill one bounded step per turn from any hook [11], added hermes as a full-pipeline agent [12], and broke opencode support entirely [13].
