Version 6.0.1

Two bug fixes. A custom EventStore can now be used, and the media tracking PercentProgress event now includes the percent progress.

Bug fixes

• Make EmitterEvent constructor public (#876)
• Add percent progress to event (#875)

Version 6.0.0

Screen time and engagement metrics

The tracker can now track screen engagement information, including the screen time and metrics for the amount of content viewed on the screen! Visit this demo to see it in action! This works nicely together with the Snowplow Unified dbt package 0.2.0.

• Add screen engagement tracking of time spent and list items scrolled on a screen (#851)
• Enable lifecycle autotracking by default (#852)

visionOS support

The iOS tracker now supports visionOS! Moreover, it provides new APIs to track visionOS events such as open and dismiss immersive space.

• Add support for visionOS (#830)
• Add VisionOS events and entities (#857)

Local event store automatic cleanup

The tracker can now automatically remove old events from the event store in situations when requests are blocked due to ad blockers or in case of longer offline usage.

• Add configurable limit for the maximum age and number of events in the event store and remove old events before sending (#860)

• Expose event store from emitter controller to be able to remove all events from database (#834) thanks to @danigutierrezayuso

• Remove the use of the FMDB dependency in SQLiteEventStore (#823)

Tackling duplicate events

We have improved the trackers to avoid sending duplicate events to the Collector by making requests serially and adjusting request timeouts.

• Add request timeout to network connection and configuration (#836) thanks to @danigutierrezayuso
• Make network requests serially in network connection (#846)

Batching improvements

The event batching algorithm has been improved to make it possible to make requests to the collector after a certain number of events accumulate in the event store (defaults to 1, but configurable to 10 or 25).

• Change default buffer option to single (#849)
• Flush events only when the buffer is full (#827) thanks to @danigutierrezayuso

Cross-navigation tracking

There is a new API to decorate outgoing links to other Web or mobile apps with user and session information.

• Add API to decorate link with user/session info (#819)

Improved concurrency model

We have reworked the internal concurrency model to be safer and more efficient.

• Improve concurrency model using a single internal dispatch queue (#820)
• Process tracked events on a serial background queue (#822)

iOS privacy manifest

We have added a SDK privacy manifest and made changes according to the latest recommendations from Apple.

• Add SDK privacy manifest file (#811)
• Remove available storage and total storage from platform context (#824)
• Add an option to override platform context properties (#865)

Other enhancements

• Return non-optional TrackerController instance from createTracker (#847) thanks to @Kymer
• Enable representing self-describing data using Codable structs (#844)
• Match BaseEvent entities API with Android tracker (#867)

Bug fixes

• Fix bundle path check to handle symbolic links (#858) thanks to @mylifeasdog

Under the hood

• Set the platform event property to tv on tvOS and mobile on watchOS (#872)
• Update copyright notices (#868)
• Update CI build (#856)

Version 5.6.0

This release adds integration with the FocalMeter system by Kantar that measures audience of content through a router meter. When configured using the FocalMeterConfiguration, the tracker makes a request with the user ID from the session context to the configured URL endpoint.

Enhancements
Add configuration to send requests with user ID to a Focal Meter endpoint (#745)

Version 5.5.0

This release adds an option to disable retrying all failed requests to the collector. The option is called EmitterConfiguration.retryFailedRequests. If configured, events that fail to be sent in the first request to the collector will be dropped. This may be useful in situations where it's necessary to prevent traffic spikes with many events being sent at the same time.

Enhancements
Add option to disable retrying any failed requests (#826)

Under the hood
Separate targets for unit and integration tests (#831)

Version 5.5.0-beta.2

This pre-release updates the 5.5.0 beta on top of the latest 5.4 patch releases.

Version 5.4.2

This release fixes the schema used for the player entity in media events. The URI of the schema was changed due to conflicts with another schema.

Bug fixes
Update vendor and version of the player schema used in media tracking (#812)

Release 5.4.1

This is a patch release that fixes an occasional crash in the StateMachine manager, and ApplicationInstall events sent before updated tracker configuration.

Bug fixes
Add thread-safety to a globalContext manager function (#809)
Fix application_install event sent with wrong configuration (#808)

Version 5.5.0-beta.1

This pre-release adds a new tracker plugin to integrate with the Kantar FocalMeter system by sending the user ID in HTTP GET request to a specified endpoint whenever the ID changes.

Enhancements

• Add configuration to send requests with user ID to a Focal Meter endpoint (#745)

Release 5.4.0

This release brings Snowplow ecommerce tracking to our Android and iOS trackers. We've added 11 new event types to make tracking and modeling ecommerce user behaviour easier. It's the same API as for the Snowplow ecommerce plugin in the JavaScript tracker, and the mobile data is already supported by the ecommerce data model. Check out the documentation to find out how to enable this, and stay tuned for the mobile version of the Ecommerce Accelerator.

This release also updates the interval for refreshing properties in the platform context entity from 0.1s to 1s in order to reduce CPU usage. Finally, it exposes a function for retrieving the payload from ConsentDocument that was removed in version 5.

Changelog

Enhancements

• Add Snowplow ecommerce events and entities (#800)
• Increase interval for updating platform context properties from 0.1s to 1s (#798)
• Expose property for retrieving payload in ConsentDocument that was removed in v5 (#804)

Version 5.3.1

This is a patch release that fixes a bug with disabled screen view autotracking configuration being ignored and wrong deserialization of timestamps when migrating from version 1.7 of the tracker.

Bug fixes

• Fix incorrect date deserialization when reading the install timestamp from 1.7 version of the tracker (#801)
• Fix disabling screen view autotracking in tracker configuration (#802)
