Callout Faster Event Harvest in changelog.
# ChangeLog
+### New Features
+
+* Event data is now sent to New Relic every five seconds, instead of every
+ minute. As a result, transaction, custom, and error events will appear in
+ near-realtime within APM and Insights.
+
+ Note that the overall limits on how many events can be sent per minute have
+ not changed. Also, metric and trace data is unaffected, and will still be
+ sent every minute.
