<Update label="Bifrost(HTTP)" description="1.6.5">
  ## ✨ Features

  * **Wafer AI Provider** - Added Wafer AI as a supported provider
  * **Async Webhooks** - New webhook delivery system for async jobs: configurable webhook endpoints (config.json, admin API, and UI), SSRF-safe delivery dispatcher with retries, delivery history with server-side pagination/search/filtering, and inference `request_id` propagation through async jobs and webhook payloads; failed jobs now inline `error`/`error_omitted` fields
  * **Reasoning Token Tracking** - Anthropic extended-thinking tokens are now tracked as `ReasoningTokens` across chat, responses, and passthrough
  * **Retain Content Toggle** - New toggle to always retain request/response content in object storage regardless of retention cleanup
  * **Throughput Metrics** - Tokens/sec throughput histogram endpoints, dashboard metrics, and throughput in model rankings and trend data
  * **MCP Metrics** - MCP metrics exported via OTEL and the telemetry (Prometheus) plugin, plus a `resource` parameter on the MCP OAuth handshake
  * **Routing Rule Validation** - Routing CEL expressions and `scope_id` references are now validated at write time in create/update handlers
  * **Network Config** - Configurable keep-alive duration in network config
  * **Object Storage Archival** - Added `archiveInterval`, `archiveGracePeriod`, and `archiveMaxObjectBytes` settings
  * **Connector User Email Export** - Connectors can now export user emails
  * **Logs UI** - Server fallback model shown in logs, content-disabled message on the logs UI, persisted page-size preference, and `prompt_tokens`/`completion_tokens` in search stats

  ## 🐞 Fixed

  * **Anthropic Fallbacks** - Fixed fallback handling and refusal responses on the Anthropic surface, and billing now attributes usage to the fallback model actually served
  * **Bedrock Reasoning** - Fixed double emission of reasoning content on Bedrock streams
  * **Fallback Model Names** - Made `RefineModelForProvider` idempotent so fallback routing no longer truncates model names (fixes Groq/Replicate/Parasail prefix handling)
  * **OpenAI Image Blocks** - `input_image` blocks now default `detail` to `auto`, fixing strict downstream validators such as vLLM (thanks [@AdityaPainuli](https://github.com/AdityaPainuli)!)
  * **Streaming Responses Surface** - Completed visible thinking items, completed Cohere terminal events with the output array, fixed reasoning item streaming in the mux, and handled line-by-line errors in streaming
  * **Azure Structured Output** - Structured output format is converted to a tool for Azure in the Anthropic integration; unsupported reasoning summary values are dropped for the Azure model router
  * **DeepSeek and SGLang** - Anthropic-compatible APIs supported via key-level setting for SGLang and used for DeepSeek chat/responses; count-tokens handling added for both
  * **vLLM** - Moved vLLM to the native Responses API
  * **Fireworks** - Added support for Anthropic APIs in Fireworks
  * **Mistral OCR** - Raw request capture and log storage enabled for Mistral OCR requests
  * **Rolling Deploy Safety** - Materialized-view read path is gated on a shape check to prevent "column does not exist" errors during rolling deploys
  * **MCP Tool Sync** - Out-of-range `tool_sync_interval` minutes are rejected to prevent nanosecond-scale sync loops
  * **Routing Rules** - Unresolved virtual keys are excluded from the scope ID set and empty routing rule fields are normalized
  * **Pricing Fallback** - Chat and Responses pricing fallback now works bidirectionally
  * **OTEL Content Attributes** - OTEL now uses the central method for content attribute checks

  ## 🐙 Closed GitHub Issues

  * [#5074](https://github.com/maximhq/bifrost/issues/5074) - Fallback routing model selection is truncating model names
  * [#5108](https://github.com/maximhq/bifrost/issues/5108) - Bedrock Converse: reasoning\_config/thinking silently dropped on cross-provider translation, fallbacks lose extended thinking
  * [#5308](https://github.com/maximhq/bifrost/issues/5308) - Responses API image blocks missing required "detail" field when converted from non-OpenAI providers

<Update label="Core" description="1.7.3">
  \[fix]: OpenAI Responses - preserve JSON schema key order in structured-output requests [@georg-wolflein](https://github.com/georg-wolflein)

  * breaking: a non-schema scalar (string/number/array) at the nested `text.format.schema.schema` position now fails request decode; boolean schemas (`"schema": true` / `"schema": false`) and objects still decode and are forwarded
  * feat: track Anthropic extended-thinking tokens as `ReasoningTokens` across chat, responses, and passthrough
  * feat: added Wafer AI provider
  * feat: added toggle for always retaining content in object storage
  * feat: added MCP metrics to OTEL and `resource` parameter to MCP OAuth handshake
  * feat: added user email export to connectors
  * feat: configurable keep-alive duration in network config
  * feat: propagate inference `request_id` through async jobs and webhook payloads
  * feat: added `WebhookDispatcher` interface wired to async job terminal states
  * fix: bedrock reasoning double emission
  * fix: anthropic fallbacks and refusal handling; bill for the fallback model actually served
  * fix: complete Cohere streaming Responses terminal events with the output array
  * fix: complete visible thinking items on the streaming Responses surface
  * fix: reasoning item streaming in mux
  * fix: handle line-by-line errors in streaming
  * fix: convert structured output format to tool for Azure provider in Anthropic integration
  * fix: default `detail` to auto on OpenAI `input_image` blocks (thanks [@AdityaPainuli](https://github.com/AdityaPainuli)!)
  * fix: SGLang Anthropic-compatible APIs via key-level setting; DeepSeek uses Anthropic endpoints for chat and responses
  * fix: count-tokens handling for DeepSeek and SGLang
  * fix: moved vLLM to native Responses API
  * fix: added support for Anthropic APIs in Fireworks
  * fix: enable raw request and store for Mistral OCR requests
  * fix: reject out-of-range `tool_sync_interval` minutes to prevent nanosecond sync loops
  * perf: hoist Replicate `parseTokenUsageFromLogs` regexps to package level
  * refactor: extract SSRF-safe dial logic into `core/network` package
