Go agent release notes | New Relic Documentation

Added new RecordCustomMetric method to Application. This functionality can be used to track averages or counters without using custom events. See Custom Metric Documentation
Fixed import needed for logrus. The import Sirupsen/logrus had been renamed to sirupsen/logrus. Thanks to @alfred-landrum for spotting this.
Added ErrorAttributer, an optional interface that can be implemented by errors provided to Transaction.NoticeError to attach additional attributes. These attributes are subject to attribute configuration.
Added Error, a type that allows direct control of error fields.

Fixed incorrect metric rule application when the metric rule is flagged to terminate and matches but the name is unchanged.
Segment.End(), DatastoreSegment.End(), and ExternalSegment.End() methods now return an error which may be helpful in diagnosing situations where segment data is unexpectedly missing.

October 12, 2016

Added support for slow query traces. Slow datastore segments will now generate slow query traces viewable on the datastore tab. These traces include a stack trace and help you to debug slow datastore activity.
Added new DatastoreSegment fields ParameterizedQuery, QueryParameters, Host, PortPathOrID, and DatabaseName. These fields will be shown in transaction traces and in slow query traces.

Added support for instrumenting short-lived processes:
- The new Application.Shutdown method allows applications to report data to New Relic without waiting a full minute.
- The new Application.WaitForConnection method allows your process to defer instrumentation until the application is connected and ready to gather data.
- Full documentation here: application.go
- Example short-lived process: examples/short-lived-process/main.go
Error metrics are no longer created when ErrorCollector.Enabled = false.
Added support for http://wwwgithub.com/mgutz/logxi. See https://github.com/newrelic/go-agent/blob/master/_integrations/nrlogxi/v1/nrlogxi.go.
Fixed bug where Transaction Trace thresholds based upon Apdex were not being applied to background transactions.
