## Changelog

### Features and enhancements

* Add support for TLS/mTLS configuration of the OpAMP client (used for [central configuration](elastic-otel-node://reference/edot-node/configuration.md#central-configuration)). Three new environment variables can be used: `ELASTIC_OTEL_OPAMP_CERTIFICATE`, `ELASTIC_OTEL_OPAMP_CLIENT_CERTIFICATE`, and `ELASTIC_OTEL_OPAMP_CLIENT_KEY`. See [the Configure central configuration doc section](elastic-otel-node://reference/edot-node/configuration.md#configure-central-configuration) for details. [#1044](https://github.com/elastic/elastic-otel-node/issues/1044)

* Improve the "preamble" log message at startup to include some details on envvars set that are relevant to the EDOT Node.js config. This uses an allowlist of non-sensitive envvars to avoid logging sensitive details. [#1018](https://github.com/elastic/elastic-otel-node/issues/1018)

* Add support for the `opamp_polling_interval` setting in Central Configuration. [#1128](https://github.com/elastic/elastic-otel-node/issues/1128)

  While this is supported in the EDOT Node.js SDK, it will only be present in
  the "Agent Configuration" UI of Kibana version 9.3 and later.

### Fixes

* Update `@opentelemetry/instrumentation-openai` dependency to version 0.7.0 to resolve a possible issue with TypeScript compilation. [opentelemetry-js-contrib#3240](https://github.com/open-telemetry/opentelemetry-js-contrib/issues/3240)
