   A New Era · React Native

   React Native 0.82 marks a major milestone by exclusively running on the New Architecture, removing support for the Legacy Architecture. The release introduces experimental Hermes V1 with performance improvements (up to 9% faster bundle loading), upgrades to React 19.1.1 with full owner stacks support, and implements DOM Node APIs for web-like tree traversal. Additional features include Web Performance APIs in canary, an optimized debug build type for Android that runs at 60 FPS versus 20 FPS in standard debug mode, and improved error reporting for uncaught promise rejections.

   Apple and Google won’t like this...

   The Free Software Foundation announced the Libriophone project, led by Rob Savois, aiming to create a fully open-source smartphone by replacing all proprietary firmware, drivers, and binary blobs with free software alternatives. Unlike existing solutions like LineageOS that still contain proprietary code, this initiative seeks complete software freedom through reverse engineering. The project faces significant challenges including the massive technical undertaking of replacing closed-source components, limited historical adoption of similar efforts like Replicant, and the dominant Apple-Google duopoly that controls mobile ecosystems.

   Liquid Glass Is Cracked, and Usability Suffers in iOS 26

   iOS 26's new Liquid Glass visual language prioritizes aesthetics over usability, introducing translucent UI elements that obscure content, animated buttons that distract users, and smaller tap targets that violate established guidelines. The update breaks long-standing iOS conventions by moving search to the bottom, removing breadcrumbs from back buttons, and adopting Android-style design patterns. Controls now appear and disappear unpredictably, making the interface harder to learn. The emphasis on visual effects creates readability issues with text overlaying images and other text, while constant animations compete for attention instead of supporting content.

   A Linear spin on Liquid Glass

   Linear rebuilt Apple's Liquid Glass design system from scratch for their mobile app redesign, creating custom SwiftUI shaders and visual effects to maintain design flexibility while supporting customizable navigation. The team implemented their own glass material using Gaussian blur, signed distance fields, and GPU-calculated lighting instead of adopting Apple's APIs, allowing them to support iOS 18 users and build expandable tab bars that adapt to different user roles. The custom implementation includes tactile feedback, variable blur effects, and accessibility features like Increase Contrast mode support.

   What is USSD (and who cares)?

   USSD, a 30-year-old messaging protocol requiring only 2G connectivity, powers hundreds of billions in financial transactions across Sub-Saharan Africa through companies like M-Pesa and Moniepoint. Behind simple menu-driven interfaces on feature phones, these platforms run sophisticated cloud architectures with ML-powered fraud detection and IoT systems. The technology demonstrates how builders solve real customer problems by choosing suitable tools over shiny ones, creating profitable businesses while serving communities with limited internet access and smartphone penetration.

    I Built the Same App 10 Times: Evaluating Frameworks for Mobile Performance

    A developer built the same kanban board application using 10 different frameworks to evaluate mobile web performance. Next-generation frameworks like Marko, SolidStart, SvelteKit, and Qwik achieve 35-39ms First Contentful Paint with bundle sizes ranging from 28.8 kB to 58.4 kB compressed, while React-based frameworks ship 118.2-176.3 kB compressed with significantly slower load times. The measurements reveal that React's architecture creates unavoidable performance costs, with bundles 2-6x larger than alternatives, while Vue via Nuxt proves established frameworks can compete when properly optimized. For mobile-first applications on cellular networks, framework choice directly impacts user experience through measurable differences in bundle size and load performance.

    React Native 0.82: A Major Leap in Native App Development with New Architectural Enhancements

    Version 0.82 removes the legacy bridge system in favor of JavaScript Interface (JSI) for direct JavaScript-to-native communication. Key improvements include the Fabric renderer for smoother UI updates, Turbo Modules with lazy-loading for efficient native functionality, and Hermes V1 engine delivering 9% faster bundle loads. The update adds DOM node API support for better web standards alignment, resulting in faster startup times, reduced memory usage, and more consistent performance across applications.

    iOS 26: Beyond Liquid Glass

    iOS 26 introduces the Liquid Glass design material, bringing significant interface changes including floating bottom navigation, repositioned search functionality, and enhanced motion design. The update moves primary actions to the bottom for better ergonomics, hides the home indicator to reduce clutter, and creates a more fluid, tactile user experience. While the aesthetic is visually striking, some inconsistencies exist across apps, and the material's effectiveness depends heavily on wallpaper choice. The changes represent a thoughtful evolution in Apple's design language, balancing visual innovation with usability improvements for larger screens.

    Google’s new deadline for Epic consequences is October 29th

    US District Court Judge James Donato has pushed back enforcement of the permanent injunction in Epic v. Google from October 22nd to October 29th. The injunction requires Google to open up its app store, stop forcing developers to use Google Play Billing, and allow developers to set their own prices. Both Epic and Google requested the one-week delay without publicly stating reasons. Google plans to file a Supreme Court appeal by October 27th and has stated it will comply with legal obligations while continuing its appeal.

    What if your operating system was React Native?

    Amazon launched Vega OS, a Linux-based operating system for Fire TV devices with React Native built directly into the platform. By embedding React Native as a system library, apps become smaller and launch faster since they share a common runtime instead of bundling it separately. The OS uses Skia for rendering, supports Expo libraries, and keeps JavaScript runtimes pre-loaded with common modules, loading only app-specific code on demand. This architecture mirrors optimization patterns used in gaming consoles and represents a significant engineering achievement, with React Native requiring over 200 engineers at Meta compared to around 15 for core React.

    New requirement for apps using Sign in with Apple for account creation

    Starting January 1, 2026, developers in South Korea must provide a server-to-server notification endpoint when using Sign in with Apple. This endpoint enables Apple to send critical updates about user account changes, including email forwarding preference modifications, app-specific account deletions, and permanent Apple Account deletions. Developers must immediately process these notifications to update user data and maintain transparency around account changes, particularly for email forwarding and deletion events. The requirement aims to give users better control over their personal data while ensuring apps comply with privacy standards and local regulations.
