April 2026 monthly summary for immutable SDKs (ts-immutable-sdk and unity-immutable-sdk). Key features delivered: - Immutable Audience SDK Core & Privacy: delivered core audience management with consent, user identity, event tracking, error handling, and type-safe event signaling; introduced IdentityType with stronger typing; unified AudienceError surface and improved OnError propagation; added typed track surface and identity workflow improvements for reliability. - Unity integration layer and pure-C# core partition: split into Unity integration and core, enabling headless builds and Unity-backed runtime; added IL2CPP build scaffolding and IL2CPP-safe JSON reader utility to support Unity deployments. - Core infrastructure, packaging, and distribution: refactored transport to HttpSend + structured TransportResult; introduced CDN bundle entry point and packaging/build pipeline; prepared publish workflow on npm for @imtbl/audience; added CDN size gate and deploy steps to CI. - GDPR/Consent lifecycle and data integrity: added ConsentStore for atomic consent persistence; introduced ImmutableAudience singleton tying together storage, queue, transport, and consent; implemented SetConsent, DeleteData, and improved error signaling via OnError; added CanTrack and CanIdentify predicates to enforce consent rules. - Reliability, quality, and test coverage: hardened shutdown sequencing and two-phase locking across lifecycle methods; guard against overlapping timer ticks in SendBatch; narrowed exception handling to IO/permission related cases; added regression tests and migrated test fixtures to reflect architecture changes; enabled nullable reference types for slice code to improve safety. Overall impact and business value: - Increased reliability and safety of consent, identity, and event data flows across web and Unity platforms. - Improved cross-platform support with a clear separation between Unity integration and core logic, enabling faster platform-specific iteration. - Ready for production CDN deployment and npm publishing, reducing time-to-market for new SDK features and privacy controls. - Stronger code quality, testing, and maintainability through nullable enablement, better error signaling, and clearer documentation.

December 2025 (2025-12) monthly update for immutable/unity-immutable-sdk: Implemented WebView/WebBrowser integration with modularization to enable testing and future web-feature extensions, and decoupled from the forked Web Browser by introducing optionalized support controlled via a symbol manager. Added the Web Browser package for testing and defined the UWB_WEBVIEW symbol to streamline feature toggling. Completed linting and code style cleanup for UwbLogConfig.cs to improve readability and long-term maintainability. These changes reduce maintenance risk, improve CI reliability, and enable faster validation of web-related features while maintaining a clean, testable codebase.

September 2025 monthly summary for immutable/unity-immutable-sdk. Focused on improving Windows IL2CPP login reliability in the Unity SDK by addressing login failures on Windows builds. Implemented a targeted fix: conditionally excluding Process.MainModule when IL2CPP is enabled, combined with a robust fallback using command line arguments to ensure login flow continues without crashes in IL2CPP environments. The change reduces user-facing login errors on Windows, improves CI/build stability, and lowers incident follow-up while preserving behavior in non-IL2CPP configurations. Verified through targeted Windows build checks and CI validation.

Performance summary for 2025-08: In immutable/unity-immutable-sdk, delivered a flexible DirectLoginOptions design enabling granular login method configuration across email, Google, Apple, and Facebook, improving initialization control and paving the way for easier provider expansion. This feature enhances authentication UX, security posture, and integration flexibility. The work emphasizes maintainability and future-ready architecture. No other major bugs recorded this period; focus was on feature enrichment and code quality.

July 2025 consolidated multi-repo delivery of direct social login across TS and Unity SDKs, enabling Google, Apple, and Facebook authentication through Passport-based flows. Included UI and authentication manager updates, achieving cross-platform parity and reducing user onboarding friction. Business impact includes higher sign-in potential and a smoother onboarding experience across web and Unity environments.

June 2025 monthly summary for immutable/ts-immutable-sdk. Focused on strengthening authentication security by revoking refresh tokens on logout and ensuring both redirect and silent logout flows properly revoke tokens, with robust error handling and test coverage.

May 2025 highlights for immutable/unity-immutable-sdk: stabilized the build pipeline, corrected artifact naming, and expanded Windows PKCE authentication testing. Fixed an executable naming mismatch by aligning the build executable name with the product name using ProductSettings.asset, reducing CI/test automation issues. Introduced a comprehensive Windows PKCE login test suite and refactored the tests for structure and reusability, improving authentication validation and test framework robustness. These efforts enhance CI stability, accelerate feedback on authentication changes, and improve maintainability of the test suite and build pipeline.

February 2025 monthly summary for immutable/ts-immutable-sdk. Focused on CI workflow improvements to inline SDK version replacement, delivering faster, more reliable builds and removing a legacy script. Updated codebase to inline replacements and ensured consistency across package manifests.
