#Skew

Last year, we introduced Vercel's industry-first Skew Protection mechanism and we're happy to announce it is now generally available.

Skew Protection eliminates version differences between web clients and servers—available for Pro and Enterprise customers.

Historical changelog entry for Improvements and fixes. Preserves release context and points to current Vercel Functions guidance.

The maximum age for Skew Protection is now extended to 60 days for requests coming from web crawlers such as Googlebot or Bingbot.

You can now configure skew protection max age to any value less than or equal to your deployment retention. Previously this was limited to 12 hours for Pro and 7 days for Enterprise.

Next.js now supports a custom deploymentId in next.config.js, enabling Skew Protection for vercel deploy --prebuilt workflows. Set your own deployment ID using a git SHA or timestamp to maintain version consistency across prebuilt deployments.
