Skew protection now available
October 23, 2025
We’ve released skew protection for all plans starting with these frameworks:
- Astro 5.15.0+
- Next.js
This feature prevents version mismatch errors when users interact with your site during a deployment.
What it fixes
When you deploy a new version of your site, users with an open browser tab may still be running the old version. If they navigate to a new page or trigger a request, the browser expects a previous version of your application, but the server returns the new version.
This version skew causes:
- Broken assets and 404 errors
- JavaScript errors
- Degraded user experience
How it works
Skew protection pins each user session to a specific Netlify deploy, ensuring the browser and server stay synchronized throughout that session.

Next steps
- Set up skew protection for your framework
- Ensure your framework can support skew protection with Netlify using our Frameworks API
