+### Deepgram Provider
+
+New Deepgram provider integration supporting speech-to-text (transcription) and text-to-speech endpoints through the gateway's unified API, with full support for retries, fallbacks, load balancing, caching, logging, and pricing.

+
+### Headroom Guardrail
+
+New Headroom partner guardrail plugin for request and response scanning, configurable through the standard guardrails workflow.

+[Guardrails Documentation](/product/guardrails)
+
+### Qwen (DashScope) Responses & Messages API
+
+Qwen models via DashScope now support the Responses API and Messages API endpoints, along with pass-through of non-OpenAI parameters (`extra_body`) for Qwen-specific features.
+
+[DashScope Documentation](/integrations/llms/dashscope)
+
+### Vertex AI OCR Support
+
+The `POST /v1/ocr` endpoint now supports Vertex AI models, bringing OCR under the gateway's full middleware stack for Google Cloud-hosted models.

+
+### Provider Updates
+
+- **OpenRouter**: Pricing now uses provider-reported cost when available, falling back to configured pricing tables
+- **Qwen (DashScope)**: Responses API and Messages API support with non-OpenAI parameter pass-through
+- **Bedrock (Mantle)**: Fixed Anthropic SSE streaming boundary handling for reliable chunk delivery
+- **Bedrock**: `temperature` is stripped from `inferenceConfig` for Claude 4-series models that deprecate it
+- **Azure AI Foundry**: Additional OpenCode compatibility fixes for Responses API routing
+- **Vertex AI**: Fixed `output_config` forwarding for Anthropic Messages requests
+- **Vertex AI**: Thinking token attribution corrected for proxy requests

+[Providers Documentation](/integrations/llms)
+
+### Fixes and Improvements
+
+- **MCP Gateway**: OAuth issuer URL now follows RFC 8414 format
+- **MCP Gateway**: Extra authorization parameters can be passed to upstream OAuth providers
+- **Streaming Logs**: `output_token_details` now included in reassembled streaming log entries
+- **Pricing**: Integration-level `pricing_adjustments` applied correctly on the config path
+- **Pricing**: Bedrock inference-profile prefix preserved for accurate cost attribution
+- **Pricing**: Meshy and Tripo3D async API pricing tracked
+- **Security**: `x-amz-security-token` masked in log paths
+- **Messages API**: Unique `tool_use` IDs generated instead of reusing provider-issued IDs, fixing deduplication issues
+- **Messages/Responses**: Instructions parameter handling corrected
+- **Forwarding**: `chat_complete_kwargs` forwarded to providers that support it
+- Updated dependencies to patch security vulnerabilities.
