Mar 1, 2026

March 2026 focused on delivering business value through feature enhancements, reliability improvements, and security hardening across three repos. Key features include Expo event context integration for better analytics in Expo apps, and the BundledPlaygroundScreen in the sample app to accelerate onboarding and testing. Build/dev tooling was unified and streamlined (Android stub/update flow, Gradle migration, CI skip for agents.toml, and CI config simplifications with composite actions). Data quality for session replays was improved by preventing recording of ignored/dropped events, increasing signal fidelity. Security posture was strengthened with patches and upgrades to critical dependencies, including iOS plugin context fixes and Angular upgrades in the Capacitor sample, alongside updated docs clarifying logging controls and Cordova deprecation.
