Next.js 15 Cache, Rust Adds to AI Salaries, and Million.js

Next.js 15 introduces significant changes to caching, requiring explicit opt-in for caching API fetches and database queries. Vercel's VP of Product Marketing, Lee Robinson, emphasizes improving the local development experience by making operations dynamic. Research indicates that skills in Rust can significantly boost AI-related job salaries. Additionally, Million.js, a minimalistic JavaScript compiler, offers a more efficient way to handle DOM updates compared to React, though it faces challenges like a steep learning curve and a smaller ecosystem.
