<Update label="Bifrost(HTTP)" description="1.4.6">
  * feat: **Bedrock: Extended document format support** - Added support for markdown (`.md`), HTML, CSV, DOC/DOCX, and XLS/XLSX file types in both request and response handling
  * feat: **Bedrock: GuardrailConfig streamProcessingMode** - Added optional `streamProcessingMode` field for sync/async guardrail processing
  * feat: **Bedrock: CachePoint support** - Added `CachePoint` schema type and handling for standalone cache point blocks in system and content messages
  * feat: **Bedrock: Native format compatibility** - Handle requests where `type` field is empty but `text` is set directly (Bedrock native format from Claude Code)
  * feat: **Bedrock: Multi-turn reasoning support** - Added `ReasoningDetails` handling in assistant messages for multi-turn conversations with thinking
  * feat: added support for replicate provider
  * feat: adds metrics push support for otel config
  * feat: adds push-gateway support for telemetry
  * feat: adds rate limits to customers and teams
  * fix: added mcp server handler to the inference routes registration
  * fix: **Bedrock: Adaptive thinking payload structure** - Fixed Opus 4.6+ adaptive thinking where `effort` was incorrectly placed under `thinking` instead of `output_config`
  * fix: **Bedrock: Stop reason conversion** - Created dedicated Bedrock stop reason converter instead of reusing Anthropic's, properly handling Bedrock-specific reasons like `guardrail_intervened` and `content_filtered`
  * fix: **Bedrock: ToolChoice auto handling** - Return `nil` for `auto` tool choice (Bedrock's default) instead of failing
  * fix: **Bedrock: Stop reason mapping** - Now uses own `bedrockFinishReasonToBifrost` map with Bedrock-specific stop reasons (`guardrail_intervened` -> `content_filter`, `content_filtered` -> `content_filter`)
  * fix: fix embedContent in genai integration
  * fix: oauth MCP servers not getting saved to config store during OAuth completion flow
  * fix: ClaudeCodeMax mode vs ClaudeCode API mode forwarding
  * fix: handle `*OrderedMap` in Gemini nested property conversion - [@Edward-Upton](https://github.com/Edward-Upton)
</Update>

<Update label="Core" description="1.4.2">
