+## [2.6.7] — 2026-03-17
+
+> Sprint: SSE improvements, local provider_nodes extensions, proxy registry, Claude passthrough fixes.
+
+### ✨ Features
+
+- **feat(health)**: Background health check for local `provider_nodes` with exponential backoff (30s→300s) and `Promise.allSettled` to avoid blocking (#423, @Regis-RCR)
+- **feat(embeddings)**: Route `/v1/embeddings` to local `provider_nodes` — `buildDynamicEmbeddingProvider()` with hostname validation (#422, @Regis-RCR)
+- **feat(audio)**: Route TTS/STT to local `provider_nodes` — `buildDynamicAudioProvider()` with SSRF protection (#416, @Regis-RCR)
+- **feat(proxy)**: Proxy registry, management APIs, and quota-limit generalization (#429, @Regis-RCR)
+
+### 🐛 Bug Fixes
+
+- **fix(sse)**: Strip Claude-specific fields (`metadata`, `anthropic_version`) when target is OpenAI-compat (#421, @prakersh)
+- **fix(sse)**: Extract Claude SSE usage (`input_tokens`, `output_tokens`, cache tokens) in passthrough stream mode (#420, @prakersh)
+- **fix(sse)**: Generate fallback `call_id` for tool calls with missing/empty IDs (#419, @prakersh)
+- **fix(sse)**: Claude-to-Claude passthrough — forward body completely untouched, no re-translation (#418, @prakersh)
+- **fix(sse)**: Filter orphaned `tool_result` items after Claude Code context compaction to avoid 400 errors (#417, @prakersh)
+- **fix(sse)**: Skip empty-name tool calls in Responses API translator to prevent `placeholder_tool` infinite loops (#415, @prakersh)
+- **fix(sse)**: Strip empty text content blocks before translation (#427, @prakersh)
+- **fix(api)**: Add `refreshable: true` to Claude OAuth test config (#428, @prakersh)
+
+### 📦 Dependencies
+
+- Bump `vitest`, `@vitest/*` and related devDependencies (#414, @dependabot)
