 ## Version 3.9.1
 
 - [#378](https://github.com/Shopify/statsd-instrument/pull/378) - Respect sampling rate when aggregation is enabled, just for timing metrics.
   Not respecting sampling rate, incurs in a performance penalty, as we will send more metrics than expected.
   Moreover, it overloads the StatsD server, which has to send out and process more metrics than expected.
