# v1.3.18

> Enterprise v1.3.18 changelog - 2026-04-12

<Update label="Bifrost Enterprise" description="v1.3.18">
  ## Changelog

  This release adds reliable cluster replication with routing-rule synchronization, expands OSS provider coverage with Mistral OCR, Azure passthrough, and OpenRouter embeddings, and tightens authentication to reject users without claims.

  ## ✨ Features

  * **Reliable Replication Logic** - Reworked cluster replication for stronger consistency and recovery guarantees across nodes
  * **Routing Rule Cluster Sync** - Routing rules now synchronize across cluster nodes with dedicated message handling, keeping every node in agreement on traffic policies
  * **OCR Endpoint** - End-to-end support for the `/v1/ocr` endpoint backed by Mistral OCR
  * **Azure Passthrough** - Native Azure API passthrough support for direct Azure OpenAI calls
  * **OpenRouter Embeddings** - Embeddings support added for the OpenRouter provider
  * **Redis TLS & Cluster Mode** - TLS and cluster-mode Redis connections, plus a fix for valkey-search query syntax
  * **OAuth MCP Hints** - Next-step hints returned on OAuth MCP client creation responses
  * **272k Token Tier & Priority/Flex Pricing** - Added 272k token tier along with flex and priority tier pricing support
  * **Go 1.26.2 Upgrade** - Upgraded the build toolchain from Go 1.26.1 to Go 1.26.2

  ## 🐞 Fixed

  * **Login Rejects Missing Claims** - Users without claims are now properly rejected at login instead of slipping through authentication
  * **Response Backfill** - Response parameter backfilling for chat completion and responses requests ensures `model`, object type, and `created` timestamp fields are always populated
  * **Pricing Sync Interval** - `pricing_sync_interval` is now correctly applied, and env variables are supported in `pricing_url`
  * **OAuth Transient Failures** - OAuth config is no longer marked expired on transient network failures
  * **Mistral Provider Cleanup** - Removed redundant provider key normalization and duplicate OCR validation from Mistral provider
