💔 Breaking Change: HTTP stack moves to httpx2
See migration plan in #4802 .
huggingface_hub v2.0 replaces its HTTP dependency with httpx2: clients and transport exceptions now come from httpx2/httpcore2 instead of httpx/httpcore. Custom client factories (via set_client_factory / set_async_client_factory) and any except clauses catching transport errors must use httpx2 types. For code that must support both v1.x (starting with v1.30.0) and v2.x, import the HTTP module from huggingface_hub.utils:
from huggingface_hub.utils import get_session, httpx
try:
response = get_session().get("https://huggingface.co/api/models/gpt2")
response.raise_for_status()
except httpx.HTTPError:
...Note that httpx2 uses the operating system's certificate trust store by default (custom CA bundles via SSL_CERT_FILE / SSL_CERT_DIR still work), logging configuration should target the httpx2 and httpcore2 loggers, and the oauth extra now requires authlib>=1.8.0.
💔 Breaking Change: deprecated APIs are removed
This release also removes all APIs deprecated in 1.x:
upload_large_folder/HfApi.upload_large_folder→ useupload_folderduplicate_space→ useduplicate_reporequest_space_storage/delete_space_storage→ use the volume APIs (set_space_volumes,delete_space_volumes)repo_type_and_id_from_hf_id→ useparse_hf_uriInferenceEndpointType.PROTECTED→ useAUTHENTICATED(create_inference_endpoint(type="protected")now raisesValueError)list_models(model_name=...)→ uselist_models(search=...)create_repo/duplicate_repo(space_storage=...)→ usespace_volumestext_generation(stop_sequences=...)→ usestop- Boolean
InferenceClient(token=...)→ pass a token string orNone
On the CLI side, the following entry points and options are gone: huggingface-cli (use hf), hf repo and hf repo-files delete (use hf repos and hf repos delete-files), hf upload-large-folder (use hf upload), hf repos create/duplicate --storage (use --volume), hf jobs ps and hf jobs scheduled ps -f/--filter (use --status/--label), and hf skills add/update --claude (Claude Code installation is now automatic).
A migration guide covering all of this is available at https://github.com/huggingface/huggingface_hub/blob/main/docs/source/en/concepts/migration_v2.md.
