v1.5.4

​

✨ Features

• Virtual Key Blocked Models — Block specific models at the virtual key provider-config level; blocked models take priority over allowed models and are enforced by governance (#3653)
• Virtual Key Ownership — Virtual keys now capture and display a created_by user attribution (#3672)
• MCP Log Attribution — MCP tool logs are stamped with user, team, customer, and business unit IDs so MCP usage can be traced like LLM usage
• Team & Business Unit Filters — Added team and business unit filters across the dashboard and logs views (#3650)
• Sticky Time Filters — Time filter selections are preserved when navigating between sidebar items (#3647)

​

🐞 Fixed

• Idle Timeout Panic — Fixed a panic in the streaming idle-timeout reader and added a guard to skip reads once the connection is closed (#3672)
• Anthropic Streaming — Preserve the tool-call stop reason in the Anthropic streaming fallback (#3640) (thanks @dicnunz!)
• TTFT Metric — Fixed the request start-time setting so the time-to-first-token metric is accurate (#3668)
• Vertex Service Tier — Map the Vertex traffic type to the correct Bifrost service tier (#3662)
• Keyless Providers — Fixed ListModels for providers configured without an API key (#3655)
• Anthropic Tools — Stopped forcing type: custom on Anthropic tool definitions (#3652)
• Node Usage Reconciliation — Added a monotonic log cursor so reconciliation no longer skips late async log writes (#3664)
• Fallback Budget Tracking — Clear the stale governance rejection flag on allow so successful fallback retries count toward budgets and rate limits (#3645)
• Virtual Keys Table — Table now fills available height with a sticky header and scrollable body (#3676)
• Sheet Layout — Removed save/cancel icons and fixed sheet layout growth in routing rule and virtual key sheets (#3675)
• Toast Click-Through — Toasts remain clickable above modal overlays (#3674)
• Direct Access Control — Reverted the virtual key access_profile_id direct access profile assignment shipped in v1.5.3; the access_profile_id column has been dropped (#3669, #3670)
