On the React Native side: a faster PlainText component, Vision Camera v5 deep dive, Gesture Handler touchable benchmarks, and multiple library releases including Firebase 26.1 migrated to Turbo Modules. The broader ecosystem section covers GitHub stacked PRs entering public preview, Node 24.19, Vite 8.2, Hono 4.13, and SolidStart 2.0. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What does Next.js 16.3 change in terms of dev server memory usage? Next.js 16.3 cuts dev server RAM usage by up to 90% during long development sessions, alongside major engine and runtime upgrades. It also adds Turbopack support for Vite-like import.meta.glob(), faster rebuilds via artifact caching, SSR handling up to 22% more requests, and support for TypeScript 7 through an experimental.useTypeScriptCli option. _Track framework version bumps like this on daily.dev before planning a Next.js upgrade._ ### What changed in React Native Blur 5.0? React Native Blur 5.0 now requires the new architecture and React Native 0.80 or later, and it deprecates raw native components. It also adds ref forwarding and react-native-web support, meaning apps still relying on the old architecture or raw native components need to migrate before upgrading. _Developers weighing React Native library upgrades can follow breaking changes like this on daily.dev._ ### What security fix shipped in pnpm 11.20? pnpm 11.20 fixes a multi-registry package substitution vulnerability by introducing registry-qualified keys, preventing a malicious package from one registry being substituted for a trusted package from another during installation. This closes a supply-chain attack vector affecting projects configured with multiple package registries. _Keep up with dependency security patches like this pnpm fix through daily.dev._ ## Similar posts on daily.dev -
