Version 4.0.4

4.0.4 (2024-11-21)

Bug fixes

• Fix multiple link click events tracked for a single tracker in case multiple trackers are initialized on the page (close #1384)

Version 4.0.3

4.0.3 (2024-11-20)

This release fixes an issue introduced in the v4 tracker release that caused multiple simultaneous sessions being started if a page was opened in multiple tabs/windows at once.

Bug fixes

• Serialize new session cookie synchronously to avoid overlapping sessions (#1381)

Version 4.0.2

4.0.2 (2024-11-11)

This release fixes a bug that caused the postPath configuration option to be ignored when making requests to the collector. It also fixes a bug in the media tracking plugin which didn't add the configured label to media events.

In the tag-based JavaScript tracker, we added a new contexts.performanceNavigationTiming option to enable/disable the performance navigation timing context entity. Since the option was previously missing, the context was added to all events. Now the context is disabled by default.

Bug fixes

• Fix ignored label property in the startHtml5MediaTracking call (#1378)
• Fix postPath configuration being ignored (close #1376)
• Add option to disable performanceNavigationTiming plugin (#1375)

Version 4.0.1

4.0.1 (2024-11-01)

This patch release fixes an issue in the HTML5 media tracking plugin in that it didn't correctly initialize and failed to track events.

Bug fixes

• Fix initialization of the HTML5 media tracking plugin so that it initializes the parent media plugin (#1369)

Under the hood

• Fix broken API docs generation by adding explicit type for EventStoreIteratorNextResult (#1367)

Version 4.0.0

4.0.0 (2024-10-28)

The release adopts the fetch API for making requests to the Snowplow collector which provides the keepalive option that enables requests to outlive the webpage they were made from.

Performance of the track calls has been improved by making cookie writes async. Our benchmarks show this improves the time it takes to track 100 events to a third of what it was in v3.

The tracker APIs have been significantly improved and simplified:

• Form and link click tracking now support event delegation and don’t require the app to refresh the tracking after page changes.
• It’s now easier to manage global context using named tags.
• Plugins add a new filter function to enable skipping events.
• The tracker API on Node.JS has been significantly revised and streamlined also thanks to the use of the fetch API.

Other changes include the YouTube and HTML5 media plugins adopting new media schemas, upgrades to the UUID package, revised defaults, and removal and deprecation of older plugins.
