Two releases worth flagging today. Hugging Face Transformers v5.9.0 adds Cohere's MoE model, a hierarchical reasoning language model, and Parakeet TDT, but breaks SAM3 and EdgeTAM text embedding input contracts, so check that before upgrading. LlamaFactory v0.9.5 extends the compatibility story further, landing Qwen3.5, Qwen3.6, and Gemma 4 support alongside a Transformer Engine backend for FP8 training. Dify v1.14.2 also ships a quiet but important security fix for tenant isolation, worth reviewing before your next deploy.
Dify v1.14.2 tightens tenant-scoped security, restores workflow tracing after human-in-the-loop resume, and fixes a spread of knowledge-base and RAG reliability issues. Here is what changed and what to check before your next deploy.
CowAgent 2.0.9 ships MCP protocol support, a new Models page in the web console, and persistent browser sessions. Builders get a pluggable tool ecosystem and centralized provider config in one release.
LlamaFactory v0.9.5 ships primary support for Qwen3.5, Qwen3.6, and Gemma 4 models alongside compatibility with Transformers v5. The release also adds several new model integrations and a Transformer Engine backend for FP8 training.
