Changelog

Track ContextSDK latest updates, new features, and fixes in our changelog.

[iOS] 5.17.0 - 2026-08-14

Generic

• Breaking: the minimum iOS deployment target is now iOS 16 (previously iOS 14). This is required by the on-device Core ML models the SDK now ships with. Apps that must keep an iOS 14 deployment target should stay on 5.16.0 - see Minimum SDK Requirements

• Add new ContextManager.setUserId(_:) function to set the user ID once for all ContextSDK products, or pass nil to clear it on sign-out. The value is stored on the device, so it's still there on the next app start. See Tracking the User ID

• Add new ContextManager.fetchCurrentActivity function that runs our on-device activity recognition models on demand and returns the probability that the user is walking, in transit, sitting and more, with a second overload to score only the activities you ask for. This API isn't part of the default build, get in touch if you'd like it enabled for your app. See Activity Recognition

• Add new sessionTimeoutSeconds configuration option to change how long the app has to stay in the background before events are grouped into a new session. It defaults to 5 minutes, so brief background and foreground transitions (like pulling down the notification shade) keep the same session. See Custom Configuration

• Custom signals whose ID can't be used, or whose numeric value is NaN or infinite, are now reported in the console once per signal ID instead of being dropped silently

Ad Tech

• Add new callback based ContextManager.fetchGoldenSignals to allow waiting for sensor data to be available

• Add support for passing custom signals directly into the golden signals call in addition to the global signals

• Golden signals are now backed by OTA delivered CoreML models allowing them to be evolved over time

• Golden signals now expose the outputs of those models: scores under m_ keys, moment embeddings as [Float] vectors with the model version under the matching mv_ key. See Golden Signals

ContextPush:

• Fix a crash in the host app when a push payload contained a NaN or infinite signal value

• ContextPush.setUserId(_:) is now deprecated in favor of ContextManager.setUserId(_:). Existing calls keep working, and for push you only need to provide the device token via ContextPush.setDeviceToken(_:)

Extension Build

• Add new uploadsEnabled parameter to ContextManager.setupForExtension to stop an extension from uploading events itself. Events are still recorded and are uploaded the next time the app launches

• Reduce the memory footprint of the notification service extension by optimizing how data is shared to the main app

[iOS] 5.16.0 - 2026-05-05

Generic

• Add new ContextManager.didReceiveMemoryWarning() function to release memory that is no longer strictly required
