TypeScript 7.0 ships a native Go compiler that cuts build times 8x-12x, though the missing programmatic API means Vue, Svelte, Astro, and Angular tooling can't fully adopt it yet. CSS gap decorations landed in Chrome and Edge 149+, finally giving grid and flexbox a clean way to style gutters without hacks. Bun's next release adds timing-aware CI sharding that splits test suites by longest-processing-time-first. ## Content **TLDR:** Next.js 16.3 is out with Turbopack memory cuts up to 90%, a 5.5x faster CI cache, and opt-in Instant Navigations that make server-driven apps feel like SPAs.

The headline feature is Instant Navigations — an opt-in mode that combines Partial Prefetching, improved ISR, and bundled prefetch requests to make server-driven apps feel like SPAs without waiting on the server. There's also an experimental Rust port of the React Compiler showing 34-46% faster cold and warm builds, versioned docs aimed at AI coding agents, and custom error boundaries with server retry logic. Andrew Clark noted some of what shipped traces back to Suspense ideas from 2017 — 90 contributors worked on the release.

Slack's CI type-checking went from 7.5 minutes to 1.25 minutes. The speedup comes from running type checkers in parallel — four by default, tunable via new --checkers, --builders, and --singleThreaded flags. The catch: no stable programmatic API in 7.0, which means typescript-eslint, Vue, Svelte, Astro, and Angular language tooling can't fully adopt it yet. That API is expected in 7.1. Anders Hejlsberg explained the Go choice as purely pragmatic — it was the right tool for the job, not a statement about Go vs Rust or C#.

The feature extends column-rule to work in grid and flexbox, adds a new row-rule property, and introduces fine-grained control via rule-inset, rule-overlap, and rule-visibility-items. A polyfill is in development for unsupported browsers.

It's an emergent integration, not a documented workflow, which is part of why it's getting attention. Separately, Patrick Collison demoed deploying a working app to Vercel in three prompts, with Claude independently choosing Upstash as the datastore — an architectural decision nobody asked it to make.
