Breaking Changes

●Issue #1

GraphQL operations in `wandb.Api` now route through the wandb-core service. Failures now raise `WandbApiFailedError` instead of `requests` HTTP exceptions. Customizations made by patching `requests` will no longer affect these GraphQL calls.

●Issue #2

The unsupported `wandb.apis.importers` API has been removed.

●Issue #3

Stale OpenAI, Cohere, and LangChain LLM integrations, including legacy autologging and tracing APIs, have been removed.

●Issue #4

The deprecated Keras `WandbCallback` and the legacy `wandb.integration.yolov8` callback package have been removed.

Migration Steps

  1. 1
    If you were relying on catching `requests` HTTP exceptions for `wandb.Api` GraphQL calls, update code to catch `WandbApiFailedError` instead.
  2. 2
    If using removed LLM integrations (OpenAI, Cohere, LangChain legacy autologging/tracing), migrate to current supported integration methods.
  3. 3
    If using the deprecated Keras `WandbCallback` or `wandb.integration.yolov8`, migrate to the current recommended callback/integration methods.

Release Summary

This release introduces new event support in the automations API and performance improvements for `Run.scan_history()`. It also removes several legacy and unsupported APIs, including older LLM integrations and callbacks.
