# v1.4.0-prerelease3

> Enterprise v1.4.0-prerelease3 changelog - 2026-04-13

<Update label="Bifrost Enterprise" description="v1.4.0-prerelease3">
  ## Changelog

  This release hardens SSO/SCIM security, adds cluster synchronization for routing rules, introduces reliable replication, and picks up OSS Azure passthrough, new pricing tiers, and a set of streaming/async safety fixes.

  ## ✨ Features

  * **Reliable Replication** - New replication logic for more dependable state propagation across cluster nodes
  * **Routing Rule Cluster Sync** - Routing rules now synchronize across the cluster via dedicated message handling, keeping all nodes in agreement
  * **Leader-Only Cluster Pricing Sync** - Only the cluster leader fetches pricing URLs, then broadcasts DB reloads to followers - cuts redundant fetches and keeps pricing consistent
  * **Terraform Account ID** - Account ID surfaced for Terraform integrations
  * **Azure Passthrough** - Native Azure passthrough support added upstream
  * **OAuth MCP Hints** - OAuth MCP client creation response now includes next-step hints for a smoother setup flow
  * **272k Token Tier Pricing** - Pricing support for the 272k token tier
  * **Flex & Priority Tier Pricing** - Pricing support for flex and priority service tiers
  * **Dockerfile Upgrades** - Base image and tooling upgrades across environment Dockerfiles

  ## 🐞 Fixed

  * **SSO Role Enforcement** - SSO login is now denied when the user has no role claims and no matching group-to-role mapping; removed the Okta Org Auth Server special case that auto-granted Admin to the first user (security hardening)
  * **SCIM Provider Fixes** - Broad fixes across SCIM controller, mapping, and Entra/Google/Keycloak/Okta/SailPoint/Zitadel providers; new SCIM tables, migrations, and config-store wiring
  * **LB Routing for GenAI & Bedrock** - Load balancing routing fixes for GenAI and Bedrock integrations
  * **Streaming Post-Hook Race** - Fixed a race where fasthttp `RequestCtx` could be recycled before transport post-hooks finished in streaming goroutines; request/response snapshots are now captured eagerly
  * **Async User Values** - User values are now propagated through all async inference handlers and job submissions
  * **Trace Completer Safety** - Trace completer accepts transport logs as a parameter instead of reading from a potentially recycled context
  * **Async Log Store Exceptions** - Fixed exception handling in async log store jobs
  * **Model Alias Tracking** - Split `ModelRequested` into `OriginalModelRequested` and `ResolvedModelUsed` for accurate alias resolution tracking
  * **MCP Tool Discovery** - Added discovered tools and tool-name mapping columns to MCP clients
  * **Guardrails Plugin** - Guardrail plugin cleanup and Bedrock guardrail adjustments
