Snowplow Golang Tracker 2.4.0 released

We are pleased to announce a new release of the Snowplow Golang Tracker.

Version 2.4.0 introduces the capability to set the Subject on each event, overwriting the Subject set at the Tracker level. This allows for more fine grained control of Subject properties when sending events to a Snowplow collector from the Golang tracker.

Read on below for more details on:

1. Set Subject per event
2. Installation and upgrading
3. Documentation and help

1. Set Subject per event

The Snowplow Golang Tracker now allows for a different Subject to be set for each event. This feature is useful when using the Golang Tracker in a server side scenario where requests are being processed but each request belongs to a different Subject, such as a web server.

You can leverage this functionality by passing a Subject into each track... method:

	trackerSubject := InitSubject()
	trackerSubject.SetUserId("123456789")

	tracker := InitTracker(
		RequireEmitter(InitEmitter(
			RequireCollectorUri("com.acme.collector"),
		)),
		OptionSubject(trackerSubject),
	)

	eventSubject := InitSubject()
	eventSubject.SetUserId("987654321")

	tracker.TrackPageView(PageViewEvent{
		PageUrl:  NewString("acme.com"),
		Contexts: contextArray,
		Subject:  eventSubject,
	})

	// Event Level 987654321 will be tracked as the UID (user_id)

	tracker.TrackPageView(PageViewEvent{
		PageUrl:  NewString("acme.com"),
		Contexts: contextArray,
	})

	//  Tracker Level 123456789 will be tracked as the UID (user_id)

2. Installation and upgrading

You can install the Snowplow Golang Tracker using gopkg or go modules:
