Next.js 16.3 reduces dev server memory usage by 90%, speeds up builds with disk caching, and improves SSR throughput by 22% under load. It also introduces Instant Navigations, an opt-in feature set that makes server-rendered apps feel as responsive as SPAs, plus root params, glob imports, and custom error boundaries. _Teams shipping Next.js upgrades track breaking changes and performance wins like these on daily.dev._ ### What is new in Node.js 26.7.0? Node.js 26.7.0 adds Perfetto support for performance profiling, private key loading through STORE loaders, Symbol.dispose in ModuleHooks, and expanded test runner coverage options. It also includes stability improvements across crypto, HTTP/2, and FFI, plus updated dependencies for npm, V8, and native libraries. _Developers maintaining Node.js services watch release notes like these on daily.dev before rolling out upgrades._ ### What does RuboCop 1.89 add with rubydex integration? RuboCop 1.89 introduces optional integration with rubydex for project-wide analysis, enabling cops to resolve cross-file references. This allows detection of issues previously invisible to single-file analysis, such as constant typos, duplicate methods, and dead code, while also reducing false positives. _Ruby teams evaluating static analysis tooling follow ecosystem updates like this on daily.dev._ ## Similar posts on daily.dev - [Codeminer42 Dev Weekly \#87](https://daily.dev/posts/codeminer42-dev-weekly-87-2bakgnsu8) · The Miners · 0 upvotes · 0 comments - [Friday Links \#38 — JavaScript Trends, AI Dev Tools & Releases](https://daily.dev/posts/friday-links-38-javascript-trends-ai-dev-tools-releases-hdzt5ou1o) · JS Dev Space · 2 upvotes · 0 comments - [Codeminer42 Dev Weekly \#76](https://daily.dev/posts/codeminer42-dev-weekly-76-jvc9gyxuc) · The Miners · 2 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#devtools](https://daily.dev/tags/devtools), [#nodejs](https://daily.dev/tags/nodejs), [#ruby](https://daily.dev/tags/ruby), [#nextjs](https://daily.dev/tags/nextjs) [View this post on daily.dev](https://daily.dev/posts/dev-weekly-123-ai-rewrites-your-product-demos-kulwpyisf)
