Bifrost(HTTP)
1.5.16

​
✨ Features

  • Failed-Request Billing — Bill for tokens a provider already processed when a stream is cancelled or times out, so partial usage is still accounted (closes #3357)
  • Airgapped Local Sync — Model catalog pricing and model parameters can now sync from local files for airgapped deployments (closes #4305)
  • MCP Extra Header Forwarding — Allowlisted per-request extra headers are now forwarded to MCP tool calls, including ping/list_tools
  • Business Unit & User Tracing — Traces now capture business unit and user names/IDs for richer attribution
  • Dashboard Export — Added a dashboard export endpoint to download dashboard data
  • Virtual Key Rankings — New Virtual Key Rankings tab in the dashboard
  • Group Traces by Sessions — Traces can now be grouped by session via config.json and Helm
  • Guardrails Evaluation Mode — Exposed evaluation mode in guardrail schemas

​
🐞 Fixed

  • Anthropic Streaming — Fixed duplicate message_start event in the Anthropic stream (closes #4556)
  • Bedrock Streaming — Encode Bedrock stream errors as EventStream exceptions, fixing ChecksumMismatch / corrupted EventStream on PostLLMHook errors (closes #4545) (thanks @jstar0!)
  • Bedrock MCP Tools — Strip provider-unsupported server tools (e.g. mcp) on the Bedrock/Anthropic Responses path instead of failing the whole request, restoring pre-v1.5.0 behavior (closes #3795)
  • Bedrock Streaming Buffering — Send Accept-Encoding: identity on Bedrock streams so responses arrive incrementally instead of buffering until generation completes (fixes TTFB collapse) (closes #4542)
  • OpenRouter Server Tools — Preserve OpenRouter server tools (openrouter:web_search) on the OpenAI Responses path instead of stripping them in filterUnsupportedTools (thanks @abdenasseraroukhsiss!)
  • Vertex Image URLs — Remote image URLs are now inlined to base64 for Anthropic-on-Vertex, which rejects url-source images (previously only documents were inlined)
  • Bedrock MiniMax — Fixed Bedrock signature handling for MiniMax models
  • Bedrock Nova — Fixed Nova model handling on Bedrock
  • Bedrock Batch — Corrected model id in Bedrock batch requests
  • Feature Gating — Resolve model names for feature gating; return 403 correctly and fix 403 errors on list-models requests
  • Governance on OAuth — Run governance on Claude Code OAuth requests when a virtual key is present; removed the skip-key-selection check from the pre-LLM hook
  • Conflict Handling — Return 409 for Conflict errors
  • Container Delete — Added explicit content-type header for container delete
  • File Serving — Handle URL-encoded file names in URL params for the single-file serving endpoint
  • Plugins Config — Fixed redaction setting in plugins config (#4486)
  • Migrations — Fixed canonical_model_view migration

​
🔧 Maintenance

  • Network Defaults — Updated default network config timings
  • Dependencies — Dependabot dependency updates
