v1.5.0-prerelease6

​

✨ Features

• MCP Tool Groups — Added tool_groups config with governance scoping (virtual key, team, customer, user, provider, API key) and camelCase Helm aliases for MCP client fields
• Enterprise Helm Overlays — Suite of composable overlays for guardrails, org governance, access profiles, customer budgets, teams, multi-customer governance, and SCIM/SSO
• Semantic Cache Helm Layers — Added values-semantic-search-redis.yaml and values-semantic-search-weaviate.yaml for Redis and Weaviate-backed semantic caches, plus a client-config overlay
• Period Parameter in Dashboard/Logs APIs — Added period param for relative time range queries on dashboard and logs endpoints
• provider_key_name Alias — Human-readable alias for routing targets and pricing overrides, resolved to key_id at config load time
• env.* References for Proxy and TLS — Proxy and TLS config fields (url, username, password, ca_cert_pem) now accept env.VAR_NAME for secret injection
• MCP Duration Strings and Hash Reconciliation — tool_sync_interval accepts Go duration strings; hash-based reconciliation prevents unnecessary MCP client restarts on config reload
• Auto-fill Incoming Model for Fallbacks — Routing rule fallback entries can omit the model; the incoming request model is substituted automatically at runtime
• Namespace Tool Type — Namespace tool container type in Responses API; non-OpenAI providers receive automatically flattened tool lists
• Cache Creation Pricing — Cache creation details for Claude models with 5-minute and 1-hour TTL pricing tiers
• Governance Config Sync — Model configs and provider governance bindings now sync from config.json to DB at startup
• business_units and Team Fields — Added business_units, team_id, calendar_aligned, and virtual_key_count to governance schema and Helm

🐞 Fixed

• WebSocket /responses Reliability — Fixed upstream handshake diagnostics, proper error capture, and WebSocket connection lifecycle in the native /responses path
• Raw Request Passthrough Removed — Removed SendBackRawRequest from all provider passthrough flows; passthrough streaming now sets proper SSE headers
• WebSocket Nil Checks — Improved sendMessageSafely nil guards, panic recovery, and client cleanup
• Routing Rule Query Normalization — Normalized query field to valid RuleGroupType and tightened schema validation
• PydanticAI Null Text Fields — Normalized null text content in PydanticAI stream response chunks
• Budget and Team Co-creation — Fixed creation of budgets and teams in the same request
• Provider Reload — Fixed keyless provider status updates during config reload; provider runtime now reloads correctly after key creation
• OTel Metrics — Fixed OpenTelemetry metrics pipeline not working (thanks @tcx4c70!)
• OTel Export — Fixed OTEL exporting to correctly show input and output messages
• Logging Request Type — Resolved request type from pending data before streaming to prevent missing Object field in error logs
• Multipart File Uploads — Write multipart metadata before file content to fix upload ordering
• Env Var Redacted Check — Added missing redacted check for env var values

• feat: Standardizes tool stripping and anthropic integration handling against anthropic, vertex and azure
