Bifrost(HTTP)

1.5.15

✨ Features

• pprof Profiling Server - Optional runtime profiling server gated by BIFROST_PPROF_PORT, with env-tunable block/mutex sampling rates and graceful shutdown alongside the main server.
• Anthropic Cache Diagnostics - Surface Anthropic’s prompt-cache diagnostics beta (cache-diagnosis-2026-04-07): responses now expose the first cache-prefix divergence point, so you can see exactly why a prompt cache missed.

🐞 Fixed

• GenAI Raw Request Passthrough - Native Vertex/Gemini batch and request bodies now follow the x-model-provider header and pass through verbatim only when Gemini or Vertex is explicitly selected, preventing a raw body from reaching a mismatched provider.
• Tool Call Metadata Preservation - extra_content on assistant tool calls (e.g. Gemini thought_signature) is now preserved across both streaming and non-streaming responses (thanks @nghodkicisco!).

​

Core

1.5.21

• fix: preserve extra_content on ChatAssistantMessageToolCall so provider-specific tool-call metadata (e.g. Gemini thought_signature) round-trips losslessly through the gateway (thanks @nghodkicisco!)
• fix: surface Anthropic prompt-cache diagnostics (cache-diagnosis-2026-04-07 beta) via new CacheDiagnostics/CacheMissReason schema, reporting the first cache-prefix divergence point on chat and responses APIs

​

Framework

1.3.21

• fix: carry tool-call extra_content through the streaming accumulator - deep-copied per chunk and accumulated across deltas (thanks @nghodkicisco!)
• chore: upgraded core to v1.5.21
