✌️ Four Heavyweights Drop Updates Four stalwarts of the JavaScript ecosystem all shipped notable releases this week, and odds are you're using at least one of them: • Gatsby v5.16 proves Gatsby, once considered neck-and-neck with Next.js in the React world, is not 'dead'. The headline feature is React 19 support. • Babel 7 just shipped its final release. "After years in the making, Babel 8 is finally ready," in release candidate form, at least. • Rspress 2.0 is a major release for the high-performance Rust-powered, but JavaScript-facing, static site generator. • Lodash 4.17.23 sounds minor, but it's a 'security reset' for the still heavily used utility library and is designed to provide a base for a longer future.
