  ## ✨ Features

  * **Runware Provider** — Added Runware provider support, including image and video generation operations
  * **Runway Image Operations** — Added Runway image generation operations
  * **Customer Attribution** — Added `x-bf-customer-id` and `x-bf-customer-name` header support for per-customer attribution
  * **Enriched Model Listing** — `list models` now returns `ContextLength`, `MaxInputTokens`, `MaxOutputTokens`, `Architecture`, and `WebSearch` pricing sourced from pricing entries
  * **Streaming Pause/Resume** — Added pause/resume flows for streaming calls
  * **Session Trace Grouping** — Added `group_traces_by_session` support to the OTEL/Datadog plugins
  * **Root Span Content Toggle** — Added a toggle to disable root-span content logging
  * **Password Policy** — Added password-policy validation with inline error and sticky save button to the security view
  * **Error Sanitization** — Internal error details (stack traces, SQL) are now sanitized before being sent to clients
  * **Cluster Discovery Env Refs** — Added `env.VAR_NAME` support to `dns_names` in cluster discovery config
  * **Server Logs Config** — Added configurable server logging
  * **Bedrock Streaming Errors** — Added `__type` return for Bedrock errors in streaming paths
  * **Secret References** — Added typed `SecretVar` env/vault reference support (`env.*`, `vault.*`) across config and UI, replacing `EnvVar`

  ## 🐞 Fixed

  * **Streaming Memory** — Reduced memory usage on streaming request/response paths
  * **Provider Config Sync** — `allow_all_keys` and `blacklisted_models` now sync from the `config.json` source of truth (thanks [@acarpe](https://github.com/acarpe)!) (closes #4640)
  * **Provider Keys Payload** — `PUT /api/providers/{provider}` no longer silently discards `keys`/blocked-model edits (thanks [@aeciolevy](https://github.com/aeciolevy)!) (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
