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.

Only Fools Write Tests — Modern engineering teams like Notion, Dropbox, Wiz, and LaunchDarkly use Meticulous to maintain E2E UI tests that cover every edge case of your web app.

🦀 OpenClaw: The Runaway AI Assistant — An intense week for a new open source TypeScript project: 150k stars on GitHub, hordes buying Mac Minis to run it, two rebrands (it was originally Clawdbot), and an ecosystem of projects the agents use autonomously (e.g. an entire social network). Another example of TypeScript at the heart of the AI boom.

Some other interesting tidbits in the broader landscape:

• GitHub is exploring solutions to tackle low-quality contributions, which could include giving you the option to disable PRs entirely or at least restrict them to collaborators. Got opinions? Join the discussion.

• How to throttle individual network requests in Chrome, rather than at a global level. Ideal for testing what happens when your dependencies load very slooooooowwwwwly....
