# v2.1.11

> Helm v2.1.11 changelog - 2026-04-29

<Update label="Bifrost Helm" description="v2.1.11">
  ## Changelog

  * Added `description` and `default` fields to numerous properties that previously had neither, including `initialPoolSize`, `disableDbPingsInHealth`, `logRetentionDays`, `asyncJobResultTTL`, `mcpAgentDepth`, `mcpToolExecutionTimeout`, `hideDeletedVirtualKeysInFilters`, `mcpDisableAutoToolInject`, and MCP `toolManagerConfig` fields
  * Added `additionalProperties: false` to multiple objects (`bifrost.config`, `bifrost.pricing`, `proxyConfig`, `concurrencyConfig`, `providerConfig`, `credentialsSecret`, and auth provider configs) to reject unknown keys at validation time
  * Added three new `bifrost.client` fields:
    * `allowPerRequestContentStorageOverride` — controls whether per-request headers can override content logging behavior
    * `allowPerRequestRawOverride` — controls whether per-request headers can override raw provider request/response passthrough
    * `mcpExternalBaseUrl` — public base URL for OAuth callbacks and discovery metadata behind a reverse proxy, supporting both string and env-var object forms
  * Added two new `bifrost.cluster.discovery` fields:
    * `bindPort` — port to bind for cluster communication
    * `dialTimeout` — timeout for discovery dial operations as a Go duration string
  * Changed `allowedOrigins` items from `oneOf` to `anyOf` and removed the redundant `not: { const: "*" }` constraint on the URI branch
  * Tightened the env-var pattern to require a valid identifier start character (`[A-Za-z_]`) for proxyConfig.url
  * Expanded `toolSyncInterval` to accept either a Go duration string (with a stricter regex) or a legacy integer (nanoseconds) for backward compatibility.
  * Marked `enforceGovernanceHeader` as deprecated in its description
  * Added `mdnsService` description for local network discovery
