# v2.1.37

> Helm v2.1.37 changelog - 2026-08-26

<Update label="Bifrost Helm" description="v2.1.37">
  ## Changelog

  * Added `bifrost.plugins.splunk` — the Splunk HTTP Event Collector (HEC) observability connector (Enterprise): one flattened event per request to `events_index` plus the derived metric set to `metrics_index`, with TLS (`ca_cert` / `insecure_skip_verify`), a content toggle (`disable_content_logging`), request-header capture, and indexer acknowledgement (`indexer_ack`, `ack_poll_interval_ms`, `ack_timeout_ms`, `max_ack_attempts`). Renders into the `splunk` plugin config.
  * Added `bifrost.plugins.otel.config.semaphore_size` and `inject_timeout` (plugin-level, both legacy and `profiles` wrapper shapes, default `10000` / `5`) — cap on concurrent in-flight trace injects and the timeout for a single inject call, so a hung collector can't hold its concurrency slot indefinitely. Renders into `semaphore_size` / `inject_timeout`. `bifrost.plugins.logging.config` accepts the same two keys (`inject_timeout` as a duration string, e.g. `"5s"`), passed through as-is.
  * Added `postgresql.primary.nodeSelector`, `postgresql.primary.tolerations`, and `postgresql.primary.affinity` to the hosted PostgreSQL deployment, so the hosted database can be steered independently of the Bifrost pod and kept off nodes that scale in. All three default to empty, so rendering is unchanged unless set.
  * Added `storage.logsStore.postgres` to point the logs store at a separate external PostgreSQL (different host and/or database) than the config store. Only applies when the logs store resolves to postgres; `enabled: false` (default) preserves existing behavior. Fields mirror `postgresql.external` (`host`, `port`, `user`, `password`, `passwordCommand`, `database`, `sslMode`, `connMaxLifetime`, `existingSecret`, `passwordKey`); with `existingSecret` the password is injected as `BIFROST_LOGS_POSTGRES_PASSWORD`. Renders into `logs_store.config`.
