Bifrost Enterprise
v1.3.19

​
Changelog

This release pulls in the OSS v1.4.23 wave: Claude Opus 4.7 support, Anthropic structured outputs, MCP tool annotations, and a large batch of provider-streaming and reliability fixes. The build toolchain reverts to Go 1.26.1.

​
✨ Features

  • Claude Opus 4.7 Support - Full compatibility with Anthropic’s Claude Opus 4.7, including adaptive thinking, the task-budgets beta header, display parameter handling, and xhigh effort mapping
  • Anthropic Structured Outputs - response_format and structured output support across chat completions and the Responses API, covering JSON-schema and JSON-object formats with order-preserving merge of additional model request fields
  • MCP Tool Annotations - Preserve MCP tool annotations (title, readOnly, destructive, idempotent, openWorld) in bidirectional MCP ↔ Bifrost chat tool conversion so agents can reason about tool behavior
  • Anthropic Server Tools - Anthropic chat schema and Responses converters now surface server-side tools (web search, code execution, computer use containers) end-to-end

​
🐞 Fixed

  • Provider Queue Shutdown Panic - Eliminated send on closed channel panics during provider queue shutdown; stale producers transparently re-route to new queues during UpdateProvider, with rollback on failed updates
  • OpenAI Responses Tool Output - Flattened array-form tool_result output into a newline-joined string for the Responses API so strict upstreams (Ollama Cloud, typed openai-go models) no longer reject it with HTTP 400; non-text blocks preserved
  • vLLM Token Usage - Treats delta.content="" the same as nil in streaming so the synthesis chunk retains its finish_reason, restoring token usage attribution
  • Bedrock Streaming & Tools - Emits message_stop for Anthropic invoke stream, case-insensitive anthropic-beta header merging, and preserves image blocks in tool results when converting Anthropic Messages to Bedrock Converse
  • Gemini Tool Outputs & Thinking Level - Handles content-block tool outputs for function_call_output and preserves thinkingLevel parameters across round-trip conversions with corrected finish-reason mapping
  • Responses Streaming Errors - Mid-stream errors in the Responses API are now captured so transport clients see failures instead of silent termination
  • Anthropic WebSearch & Fallbacks - Removed the Claude Code user-agent restriction so WebSearch tool arguments flow for all clients; fallback fields are dropped from outgoing Anthropic requests to avoid schema validation errors
  • Async Context Propagation - Preserve context values in async requests so downstream handlers retain request-scoped data
  • Custom Providers - Allow custom providers without a list-models endpoint to accept any model rather than restricting on virtual key registration
  • OTEL Plugin - insecure defaults to true in config.json and emitted OTEL metrics now include fallbacks
  • Config Schema Validator - Corrected JSON-path lookups for concurrency and SCIM blocks, and reformatted transports/config.schema.json for readability
  • Helm Chart - Validation fixes, prerelease tag removed, and mcpClientConfig templating corrected
  • CI Egress Hardening - step-security/harden-runner switched from audit to block across all GitHub Actions workflows with explicit allowed-endpoints per job

​
🛠️ Build
