Next.js 16.3: faster, better, stronger. My highlights: 0️⃣ Faster dev & builds Shoutout to Fable for improving memory use, and the team for landing the incremental 𝚗𝚎𝚡𝚝 𝚋𝚞𝚒𝚕𝚍 cache. 1️⃣ Instant navigations are 🔥 The people wanted SPAs, they shall get SPAs. By turning on instant navs (which will soon be default), your agent is basically forced to make things fast. 2️⃣ Agent-native DX You can still ship "slow" navs if you want, e.g. by blocking navs on server-side data fetching ala PHP olden days. But even then, your agent will be given *choices*, like setting up a <𝚂𝚞𝚜𝚙𝚎𝚗𝚜𝚎 𝚏𝚊𝚕𝚕𝚋𝚊𝚌𝚔> for instant loading shells. Agents also get built-in versioned docs. This is our best release for agents by far, which will also make your upgrading journey very smooth. I've had an easy time bumping my projects to 16.3 and enabling instant navs, having my agent migrate everything without issues. And so much more. 16.3 is more cost-efficient to serve, both in self-hosting and serverless environments. Faster to type-check… Thank you to the 90 contributors to this release!
