## Notes

#### Features

-   Updated `koa` instrumentation to properly wrap `Router` when using `@koa/router@15.0.0`+ ([#3550](https://github.com/newrelic/node-newrelic/pull/3550)) ([f1e08ad](https://github.com/newrelic/node-newrelic/commit/f1e08ad9fe200138ab9ed32e423517f64e41af49))

    -   To assign a ratio based sampler, set `config.distributed_tracing.sampler.root`, `config.distributed_tracing.sampler.remote_parent_sampled`, or `config.distributed_tracing.sampler.remote_parent_not_sampled` to `{ trace_id_ratio_based: { ratio: <float between 0 and 1> }}`
    -   To assign via environment variables set `NEW_RELIC_DISTRIBUTED_TRACING_SAMPLER_<TYPE>='trace_id_ratio_based'` and `NEW_RELIC_DISTRIBUTED_TRACING_SAMPLER_<TYPE>_RATIO=<float between 0 and 1>` where `<TYPE>` is one of `ROOT`, `REMOTE_PARENT_SAMPLED`, or `REMOTE_PARENT_NOT_SAMPLED`
-   Updated configuration to allow `adaptive.sampling_target` to be set for `config.distributed_tracing.sampler.root`, `config.distributed_tracing.sampler.remote_parent_sampled`, and `config.distributed_tracing.sampler.remote_parent_not_sampled` ([#3532](https://github.com/newrelic/node-newrelic/pull/3532)) ([44f51dd](https://github.com/newrelic/node-newrelic/commit/44f51dd5583e74aef1e2d0ee9483d51d5ff786c3))

### Support statement:

We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date. (<https://docs.newrelic.com/docs/new-relic-solutions/new-relic-one/install-configure/update-new-relic-agent/>)
