What's New

Core release adds Databricks, GitHub Copilot providers, and virtual MCP support

Breaking Changes

  • Clear Anthropic raw-body passthrough for non-Claude models on multi-family providers

New Features

  • New Databricks provider for Model Serving and Unity AI Gateway
  • New GitHub Copilot provider with installation tokens
  • Virtual MCP server support
  • Project governance dimension in request context
  • Native raw request redaction for Anthropic and Gemini

Improvements

  • Added Baseten to Hugging Face inference provider discovery
  • Extended unverifiable-signature fail-soft logic
  • Added optional prompt-cache breakpoint synthesis

Bug Fixes

  • Map forced tool choice `any` to `required` on OpenAI Responses
  • Preserve max reasoning effort for GPT-6 Astra
  • Fix Bedrock message null content serialization
  • Marshal required nullable response fields as null
  • Accept top-level arrays from OpenAI-compatible APIs

Upgrade Notes

Review Anthropic passthrough settings as non-Claude models on multi-family providers now convert requests instead of passing payloads. Ensure Bedrock message content fields are not empty to avoid serialization errors.
