huggingface_hub v1.0 release introduces HTTPx backend, Typer CLI, and Xet-based transfers

AI Impact Summary

huggingface_hub has reached v1.0, signaling a mature, API-centric platform with major architectural shifts: HTTP backend via httpx, a redesigned Typer-based CLI, and the Xet protocol for large object transfers. These changes improve performance and scalability for distributing models, datasets, and Spaces, but require downstream libraries and user code to adapt to new transfer APIs (HTTP Commit API) and CLI workflows. While backward compatibility is emphasized, Transformers explicitly requires v0.x in its v4 releases and v1.x in its upcoming v5, so coordinated upgrades and thorough integration testing are essential to avoid build breaks.
