May 1, 2026

2026-05 monthly summary focused on delivering a rebranded, stable onboarding experience for the macOS onboarding flow in the duckduckgo/apple-browsers repo. Implemented the macOS Contextual Onboarding Redesign (2026 Rebranding) behind the onboardingRebranding feature flag, introducing a layered dialog system and new screens (TrySearch, SearchDone, TrySite, Trackers, FireButton, EndOfJourney). The redesign removes background animations to improve performance and consistency, and introduces bubble transitions with inline cross-fades. Fixed background illustration positioning by using an overlay approach to eliminate animation artefacts, and updated theming tokens to support new states (optionsListHoverColor, optionsListPressedColor) plus a new CTAButtonStyle. All changes are scoped to the rebranded flow and do not affect the legacy onboarding. Conducted comprehensive manual validation across light/dark modes and different device scenarios to ensure parity and smooth UX across platforms.

April 2026 focused on enabling a future macOS contextual onboarding rebrand through feature-flagged infrastructure, UI scaffolding, and cross-platform design alignment. Implemented a new onboardingRebranding feature flag, added copied onboarding dialogs and a dedicated rebranded factory/provider, and wired runtime dialog selection into the existing flow. Delivered a redesigned macOS TrySearch dialog gated behind the flag, preserving the legacy UI when the flag is off. Added supporting UI components (FadeInView) and theming changes to support the rebrand roadmap. No user-facing changes occur unless the flag is enabled, reducing risk while setting up business-ready branding consistency across macOS and iOS.
