TanStack Router 1.170.4 + Start 1.168.6: CSS runtime inline y URL templates

El release del 17 may bumpea @tanstack/react-router a 1.170.4, @tanstack/react-start a 1.168.6 y router-core a 1.171.2. Llegan inline CSS runtime controls y asset URL templates en Start, más un fix para paths con guion bajo literal bajo layouts sin path. Ojo si usás Start: ahora podés ajustar cómo se inyecta el CSS en runtime sin tocar el bundler, y los assets son referenciables por template — clave para builds multi-tenant.

Next.js 16.3.0-canary.7 abre el ciclo del próximo minor

Vercel publicó [email protected] en npm el 15 may, arrancando la rama 16.3 después del parche de seguridad 16.2.6 de la semana pasada. Todavía no hay blog post de features estables — canary sirve para probar Turbopack y RSC fixes antes del estable. Si self-hosteás Next.js, seguí en 16.2.6 (o 15.5.18) hasta que salga 16.3 GA; el canary es para validar la migración temprano.

shadcn CLI 4.7 soporta package.json#imports y target aliases

El nuevo [email protected] ya entiende package.json#imports para instalar, reescribir imports y resolver registries de terceros. En vez de depender solo de compilerOptions.paths de TS, podés usar aliases privados estilo #components/* y referenciarlos desde components.json. Los registry items además aceptan target aliases en files[].target (ej. "target": "@ui/ai/prompt-input.tsx") — un alivio gigante en monorepos donde shared UI vive en un package y app code en otro.

TanStack ecosystem bump: 22 paquetes sincronizados

El release publicó 22 paquetes en un solo tag: [email protected], [email protected], [email protected], [email protected], [email protected], plus zod-adapter, devtools y eslint-plugin actualizados. Manuel Schiller lideró el PR de inline CSS runtime y el fix de underscore paths. Si tenés monorepo con TanStack, bumpealo en bloque para evitar version skew entre router y adapters.

Chrome stable: refresh desktop + Android el 12 may

El equipo de Chrome publicó updates de Stable Channel for Desktop y Stable Update for Android el martes 12 may, más una tanda de beta (desktop, Android, iOS, ChromeOS) y dev al día siguiente. Si seguís Chrome 145 en producción, revisá la entrada de Extended Stable que también recibió bumps — son fixes y patches de seguridad típicos de mid-cycle, sin features nuevas notables.

Tendencias Destacadas

Semana tranquila después del rewrite Rust de Bun y el patch de seguridad masivo de Next.js: el ecosistema está en modo housekeeping. Si venías postergando bumpear monorepos con TanStack o shadcn, esta es la ventana — los releases son aditivos y los riesgos están bien acotados.

TanStack Router 1.170.4 + Start 1.168.6: inline CSS runtime and asset URL templates

The May 17 release bumps @tanstack/react-router to 1.170.4, @tanstack/react-start to 1.168.6 and router-core to 1.171.2. Start gains inline CSS runtime controls and asset URL templates, plus a fix for literal underscore paths under pathless layouts. If you ship on Start, you can now tune runtime CSS injection without poking the bundler, and assets are template-addressable — clutch for multi-tenant builds.

Next.js 16.3.0-canary.7 opens the next minor cycle

Vercel published [email protected] to npm on May 15, kicking off the 16.3 line after last week's 16.2.6 security patch. There's no stable feature blog yet — canary is the channel for vetting Turbopack and RSC fixes before they land in stable. If you self-host Next, stay on 16.2.6 (or 15.5.18) until 16.3 GA; the canary is for early migration testing.

shadcn CLI 4.7 ships package.json#imports and target aliases

The new [email protected] reads package.json#imports for installing components, rewriting imports, and resolving third-party registries. Instead of leaning only on TS compilerOptions.paths, you can use private aliases like #components/* and reference them from components.json. Registry items can also use target aliases in files[].target (e.g. "target": "@ui/ai/prompt-input.tsx") — a huge ergonomics win in monorepos where shared UI lives in one package and app code in another.

TanStack ecosystem bump: 22 packages aligned

The release pushed 22 packages under one tag: [email protected], [email protected], [email protected], [email protected], [email protected], plus updated zod-adapter, devtools, and eslint-plugin. Manuel Schiller led both the inline CSS runtime PR and the underscore-path fix. If you ship a TanStack-heavy monorepo, bump the whole set together to avoid version skew between router and adapters.

Chrome stable: desktop + Android refresh on May 12

The Chrome team published a Stable Channel for Desktop and Stable Update for Android on Tuesday May 12, followed by a Beta wave (desktop, Android, iOS, ChromeOS) and a Dev refresh the next day. If you track Chrome 145 in prod, check the Extended Stable entry — bumps and security patches, typical mid-cycle housekeeping, no shiny new features.

Notable Trends

Quiet week following Bun's Rust rewrite and Next.js's mass security patch — the ecosystem is in housekeeping mode. If you've been postponing TanStack or shadcn monorepo bumps, this is the window. Releases are additive and risk surface is small.

Vercel a publié [email protected] sur npm le 15 mai, ouvrant la branche 16.3 après le patch de sécurité 16.2.6 de la semaine passée. Pas encore de blog stable — canary sert à valider Turbopack et les fixes RSC avant la GA. Si vous self-hostez, restez sur 16.2.6 (ou 15.5.18) jusqu'à la 16.3 GA.

Tendances Notables
