Changelog
Release ontransports/v1.6.0. Adds Runware and Runway providers (image and video generation), streaming pause/resume, customer attribution via x-bf-customer-id / x-bf-customer-name, and typed SecretVar env references replacing EnvVar across config and UI.✨ Features
- Runware Provider - Added Runware as a supported provider, covering both image and video generation operations through the standard provider configuration. Connect it like any other provider via
config.jsonor the UI. Docs - Runway Provider - Added Runway image generation operations, so Runway can be routed and load-balanced alongside other image providers. Docs
- Customer Attribution - Added
x-bf-customer-idandx-bf-customer-namerequest headers so usage, cost, and traces can be attributed per end customer, in addition to the existing user, team, and business-unit dimensions. - Enriched Model Listing -
list modelsnow returnsContextLength,MaxInputTokens,MaxOutputTokens,Architecture, andWebSearchpricing sourced from the pricing catalog, so clients can size requests and estimate cost without a second lookup. - Streaming Pause/Resume - Added pause and resume flows for streaming calls, allowing an in-flight stream to be held and continued rather than torn down and restarted. Docs
- Session Trace Grouping - Added
group_traces_by_sessionto the OTEL and Datadog plugins so spans from the same session roll up under one trace, plus a toggle to disable root-span content logging for noisy or sensitive payloads. Docs - Password Policy - Added password-policy validation in the security view, with inline field errors and a sticky save button so policy violations are caught before submission.
- Error Sanitization - Internal error details such as stack traces and raw SQL are now sanitized before responses are returned to clients, preventing implementation details from leaking to callers.
- Cluster Discovery Env Refs - Added
env.VAR_NAMEsupport todns_namesin cluster discovery config, so peer addresses can be supplied from the environment instead of being hard-coded. - Server Logs Config - Added configurable server logging so log verbosity and output can be tuned per deployment.
- Bedrock Streaming Errors - Bedrock errors on streaming paths now carry the
__typefield, so clients receive a typed error instead of an opaque stream failure. - Secret References - Added typed
SecretVarreferences across config and UI, replacing the oldEnvVar. References currently resolve from environment variables (env.VAR_NAME); the typed form lets config declare where each secret comes from rather than inlining values.
🐞 Fixed
- Streaming Memory - Reduced memory usage on streaming request/response paths.
- Provider Config Sync -
allow_all_keysandblacklisted_modelsnow sync from theconfig.jsonsource of truth (closes #4640). - Provider Keys Payload -
PUT /api/providers/{provider}no longer silently discardskeys/ blocked-model edits (closes #4648). - Custom Header Base URL - Fixed base-URL protocol handling when a custom header is set.
- VK Quota Usage - Fixed the start time for virtual-key quota model usage.
- Model Budgets - Fixed model budget attachment from virtual keys.
- Structured Streaming Errors - Preserved structured errors for streaming plugin blocks.
- Log Hygiene - Removed leaking request bodies from console logs.
