Snowplow Android and iOS Trackers version 4.1

Announcements New releases
1

We are pleased to announce the release of our mobile trackers: Snowplow iOS Tracker and Android Tracker version 4.1.

This release improves the anonymous tracking functionality by anonymising additional properties in Subject and Session. In Subject, the manually set userId, domainUserId, networkUserId, and ipAddress are now anonymised. In Session, previousSessionId is anonymised to prevent stitching independent anonymous sessions.

Now the tracker also sets the page_referrer and page_url atomic event properties for Screen View events. This improves compatibility with the Referer parser enrichment.
