<h2>Octane: compiled React-compatible framework from the Inferno author</h2>
<p>Dominic Gannaway announced Octane, a compiled successor to Inferno that keeps React’s programming model — hooks, Suspense, Actions — but drops the virtual DOM, Rules of Hooks, and manual dependency arrays. The compiler infers what your code captures and generates reactivity itself. It ships with TanStack, React Three Fiber, Lynx, and StyleX integrations, plus a compatibility layer for dropping Octane components into existing React apps. Currently in alpha, beta expected soon. Early testers report benchmark parity with Solid, Remix V3, and vanilla JS. <a href="https://daily.dev/feed-by-ids?id=6Gl3JsuUv&amp;id=JfKIpkYBm&amp;id=KbjjLf1AU" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Nuxt 4.5.1 and 3.21.10 patch eight vulnerabilities including critical DevTools RCE</h2>
<p>Nuxt released security patches across 4.5.1, 3.21.10, and @nuxt/devtools 3.3.1 fixing eight vulnerabilities. The most urgent: an unauthenticated RCE in DevTools exposed via the Vite HMR socket, and a server-side RCE via server island props when vue.runtimeCompiler is enabled. Additional high-severity issues include a route rule authorization bypass via case-sensitive matching and cross-user payload disclosure on cached pages in 4.x. If you use authenticated pages with Nuxt caching, purge CDN and edge caches after upgrading. <a href="https://daily.dev/posts/xdlBhO0fF" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Kimi K3: 2.8T open-weight model tops Frontend Code Arena, requires 64 H100s to self-host</h2>
<p>Moonshot AI released Kimi K3 weights on July 27 — 2.8 trillion total parameters, 104B active per token via MoE, 1M token context, and a Modified MIT license. It scores 57 on the Artificial Analysis Intelligence Index (behind Claude Fable 5 at 60) and ranks first on the Frontend Code Arena with an Elo of 1,679. Moonshot claims roughly Claude Fable 5 parity on coding at about a third of the cost per token, though it runs four times slower. The infrastructure reality: ~1.4TB of weights and 64 H100s across eight servers to self-host, so most teams will use an inference provider. <a href="https://daily.dev/posts/dXT19nYW1" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>TypeScript 7 hits 7.5x faster builds via parallel type checking</h2>
<p>TypeScript 7 ships parallel type checking that splits files across concurrent checkers. On the VS Code codebase — 1.3 million lines, ~8,000 files — TypeScript 6 took ~50 seconds; TypeScript 7 finishes in ~6.5 seconds. On a 16-core machine that drops to ~4.5 seconds, a 12x improvement at roughly the same memory footprint. The default spins up four concurrent checkers. <a href="https://daily.dev/feed-by-ids?id=t4MNzhMSw&amp;id=xNLHmdNYn" target="_blank" rel="noopener nofollow">Read more</a></p>

<li><strong>TanStack Table V9 beta: tree-shakable features, TanStack Store state, ~5kb minimum bundle:</strong> TanStack Table V9 beta rebuilds the architecture around opt-in tree-shakable features (minimal table starts at ~5kb), replaces internal state management with TanStack Store for fine-grained re-render control, and includes a useLegacyTable hook for gradual migration — the rewrite was partly triggered by React Compiler stable breaking V8 patterns. <a href="https://daily.dev/posts/VG00OY4OM" target="_blank" rel="noopener nofollow">Read more</a></li>
