v1.5.0-prerelease7

​

✨ Features

• Passthrough Streaming Accumulation — Added accumulator for passthrough streaming responses, enabling proper logging and cost tracking on raw provider streams
• Auto-Resolve Provider — Inference and integration routes now auto-resolve the provider when no provider prefix is given on the model name
• Per-Request Content Logging Overrides — Opt-in per-request overrides for content logging and raw request/response visibility, with DB migrations and live-reload
• Unified Dimension Headers (x-bf-dim-*) — New unified dimension headers automatically forwarded to logs, traces, Prometheus, and Maxim tags
• OpenAI Realtime Audio (Base64) — Audio base64 encoding support for OpenAI realtime provider (thanks @Mahmoud-Khater!)
• Local Cache Hit Rate Speedometer — Dashboard speedometer showing local cache hit rate (thanks @loss-and-quick!)
• VK-Scoped Model Lists — Model list endpoints now scoped to virtual-key-allowed providers and models via request headers
• MCP Reverse Proxy OAuth — External base URL support for reverse-proxy MCP OAuth flows
• schemas.Duration Type — Go duration string support for MCP, Redis, Weaviate, and mocker duration fields
• Finish Reasons in OTEL Root Spans — Finish reasons added to root spans, with correct model and provider names propagated
• Routing Rules Scope Cache — Cache routing rules per scope upfront, plus model-catalog routing engine label and icon

​

🐞 Fixed

• OTEL Cost Info — Fixed cost info in OTEL calls and response tools
• Migrations Conflict Resolution — Fixed migrations for conflicts
• WebSocket /responses Reliability — WebSocket responses now working with improved logging, cost tracking, and VK stripping
• MarshalJSON Auto-Redaction — Removed MarshalJSON auto-redaction; explicit redaction now applied to env-backed fields in ProxyConfig, ClientConfig, and AzureKeyConfig
• Vertex google/ Prefix — Strip google/ prefix from Vertex model IDs across all request types
• Vertex Multi-Region Routing — Multi-region-only models now route to multi-region endpoints when the provider key is configured for a single region only
• OAuth Token expires_at — expires_at is now nullable; refresh/reconnect guarded on nil expiry
• OpenAI Responses Tool Fields — Preserved tool fields in OpenAI responses (thanks @princepal9120!)
• Semantic Cache Determinism — Deterministic request hashing and CacheDebug propagation in streaming (thanks @loss-and-quick!)
• Streaming Pool-Reuse Corruption — Snapshot RequestType before closure to prevent pool-reuse corruption in streaming requests
• Self-Looping Chain Rules — Chain rules with self-loops now continue evaluating subsequent rules instead of halting
• Default Routing Provider Filter — Filter out unconfigured providers in default routing
• Network Config Fallback for Ollama/SGL — Fall back to network config if key config URL is not set for Ollama and SGL
• base_url Backward Compatibility — base_url added to network_config for backward compatibility
• Streaming Pipeline RawRequest — Propagate RawRequest through streaming pipeline and fix pool leak (thanks @loss-and-quick!)
• Logging Streaming Errors — Improved streaming error handling in logging plugin (thanks @loss-and-quick!)
• governance_budgets Join — Corrected join condition to use virtual_key_id
• OTEL Input/Output Messages — Fixed input/output messages propagation to root span
• resolvePeriod UTC — Fixed UTC handling in resolvePeriod time calculation
• Dockerfile.local — Dockerfile.local now uses local packages (thanks @ReStranger!)
• Semanticcache Provider Keys — Inherit provider keys from global client in semanticcache plugin

​

🔧 Maintenance

• Helm Chart Upgrades — Guardrails Helm chart upgrade; Helm apply step added; Kubernetes pod-discovery RBAC templates added
• Dashboard UI Polish — Popover scrolling, sheets/cluster page indentation, save-button validation, dialog overflow, fixed ChartCard heights, broader ComboboxSelect adoption (pricing, routing, assignment fields)
• Plugin Lifecycle Logging — Added log level param to AppendRoutingEngineLog; trimmed unused dependencies in semanticcache
• OpenAPI Regeneration — Regenerated openapi.json
