2.4.9 is hot off the press with a couple of cool new rules! - If you're using CSS, you'll probably love noDuplicateSelectors, which helps keep your styles clean and lean - If you're worried about your dependency's licences, you can keep it in check with noUntrustedLicenses

Now available: Depot CI 🚀 ⚡ CI was designed in 2015 when writing code was the bottleneck. That era is over. One engineer with agents is now operating like a team of 20. They're generating more code, across more branches, at a pace that would have been unimaginable three years ago. And all of that code has to flow through CI. Teams can hit 10x code velocity with agents today. But CI can't keep up. The slowest part of software development is no longer writing code. It's everything that comes after. Three years ago, we started by making the container build step faster. Then we made the runner faster. Then the individual build tools inside via remote caches. But we could only accelerate about 30% of the pipeline. The other 70% of CI, the control plane, the orchestration, the plumbing, etc., was always someone else's infrastructure. We could optimize around it, but we couldn't touch it. So we built our own. From scratch. Depot CI is a programmable CI engine built for how you're actually building software today. It's not a faster GitHub Actions. Think of Actions as a language Depot CI speaks — the first frontend to the engine, not the only one. Our own orchestrator. Our own compute subsystem. Our own plumbing. Prewarmed runners with your custom image already loaded. SSH debugging, CPU/memory metrics, parallel step support, and full API access built in. GitHub Actions syntax support from day one. depot.dev/blog/now-available…

Now available: Depot CI

We're excited to announce that Depot CI, our own programmable CI engine, is now generally available to everyone who wants to accelerate their CI in this new era of software engineering.

Impressive performance! Regarding the Biome benchmark, our CLI does a pre-traversal for discovering nested configurations and ignore files, which increases our processing time slightly. Something we are definitely looking into to improve!

ESLint was hit with a $100 bill from @Netlify for going over the limits of the open source plan. This has *never* happened before in the many years we've been on Netlify and support can't tell me what happened. Overall user traffic was down in 2025. Can anyone help?

Quick React reminder that `useId()` is underrated You can `useId(…)` + the `form={…}` attribute to submit forms from buttons outside the form element Avoids the whole `useEffect()` or `useRef()` juggling you'd otherwise have to do
function SomeDialog() { const formId = useId(); const saveProfile = async (formData: FormData) => { /* ... */ }; return ( <Dialog> <DialogHeader>Edit Profile</DialogHeader> <form id={formId} action={saveProfile}> <Input name="name" /> </form> <DialogFooter> <Button variant="secondary">Cancel</Button> <Button type="submit" form={formId}> Save </Button> </DialogFooter> </Dialog> ); }
