Following the Node.js 16 end of life on September 11, 2023, we are deprecating Node.js 16 for Builds and Functions on February 6, 2024.

• Will my existing deployments be affected?
• No, existing deployments with Serverless Functions will not be affected.
• When will I no longer be able to use Node.js 16?
• On February 6, 2024, Node.js 16 will be disabled in project settings. Existing projects using 16 as the version for Functions will display an error when a new deployment is created.
• How can I upgrade to Node.js 18?
• You can configure your Node.js version in project settings or though the engines field in package.json.

We've upgraded our Managed Infrastructure resulting in up to 45% faster routing at p99 and reliability improvements for all plans.

When a request is made to a Vercel-managed site, traffic is routed to the nearest Edge Network region with our Anycast routing. Vercel processes the request, identifies the deployment to serve, and instantly retrieves related metadata about the requested deployment.

Now with optimized metadata retrieval and routing, this performance enhancement benefits all workloads. Responses to static resources are then fetched from storage, or dynamic content is generated through Vercel Functions, based on the routing details from the deployment metadata.

These infrastructure improvements benefit all existing and new deployments. Deploy now or learn more about Vercel's Managed Infrastructure.

ruby "~> 3.2.x"

Ruby v3.2 is now generally available, and is the new default runtime version for Ruby based Builds and Serverless Functions. Additionally, Ruby v2.7 will be discontinued on December 7th, 2023.

• Existing deployments that use Ruby v2.7 will continue to work
• New deployments will use Ruby v3.2 by default, or if ruby "~> 3.2.x" is defined in the ‌Gemfile‍​‍​‍‌‍‌
• After December 7th, 2023, new deployments that define ruby "~> 2.7.x" in the ‌Gemfile‍​‍​‍‌‍‌​‍‌‍‍‌‌‍‌‌‍‍‌‌‍‍​‍​‍​‍‍​‍​‍‌‍​‌‍‌‍‍‌‌​‌‍‌‌‌‍‍‌‌​‌‍‌‍‌‌‌‌‍​​‍‍‌‍​‌‍‌‍‌​‍​‍​‍​​‍​‍‌‍‍​‌​‍‌‍‌‌‌‍‌‍​‍​‍​‍‍​‍​‍​‍‌‍​‌‌​​‌‍‍‌​‍‌‍​‍‌‍​‌‍‌‍‌​‍‌‍‌‌‌‍‌​‌‍‍‌‌‌​​‌‍‌‌​‌​​‌‌‍​‌‍‌‌‌‍​‌‌‍‌‍‍‌‍​‌​‍‌‌‌‌‌​‌​​‍​​‌‌​‍​‌‍‍‌​​‌‌​‍‌‌‍‍‌‍‌​​‌‌‍‌‌‌​​‌‌‍‍‌​‍‌‍‌‌​​‌‌‍‌‌​‍​‍‌‌ will no longer build

Only the minor version (3.2) is guaranteed, meaning we will always use the latest patch version available within the minor range.

Comments on your deployments can now be converted into Jira issues. This makes it easy to take action on feedback in the workflows your team is already using.

You can name your issue and select the project and issue type without leaving your deployment. Issues retain the full thread history with any attached images and include a link back to where the comment was left.

Jira is part of our growing collection of integrations for comments which includes Slack and Linear, available to Pro and Enterprise users as well as Hobby users with public git repositories.

As of today, Node.js version 20 can be used as the runtime for Builds and Serverless Functions. Select 20.x in the Node.js Version section on the General page in the Project Settings. The default version remains Node.js 18.

Node.js 20 introduces several new features including:

• New experimental permission model
• Synchronous import.meta.resolve
• Stable test runner
• Performance updates to V8 JavaScript Engine and Ada (URL Parser)

Node.js 20 is faster and introduces new core APIs eliminating the need for some third-party libraries in your project. Support for Node.js 20 on Vercel is currently in beta.

The exact version used by Vercel is 20.5.1 and will automatically update minor and patch releases. Therefore, only the major version (20.x) is guaranteed.

Vercel Cron Jobs let you to run scheduled jobs for things like data backups or archives, triggering updates to third-party APIs, sending email and Slack notifications, or any task you need to run on a schedule.

By using a specific syntax called a cron expression, you can define the frequency and timing of each task. Cron Jobs work with any frontend framework and can be defined in vercel.json. You can use them to run your Serverless Functions and Edge Functions.

During the beta, we made Cron Jobs more secure by providing an environment variable with the name CRON_SECRET. We also added support for Deployment Protection and Instant Rollback.

Cron Jobs are now included for customers on all plans. Per account, users on the Hobby plan will have access to 2 Cron Jobs, users on the Pro plan will have access to 40 Cron Jobs, and users on the Enterprise plan will have access to 100 Cron Jobs.

Check out our documentation or deploy an example with Cron Jobs.

Vercel can now automatically detect and replay layout shifts on your deployments from the Vercel Toolbar.

Layout shifts are reported and notified through the Toolbar. Each reported shift includes a summary of what caused the shift and how many elements it affected. Additionally, you replay and animate the shift to see it again.

The Toolbar is automatically added to all Preview Deployments, but can also be used in localhost and in production (likely behind your own staff authentication checks) when using the @vercel/toolbar package.

A security vulnerability was discovered that affects Sentry’s Next.js SDK, which made it possible to exploit Sentry’s Tunnel feature to establish Server-Side Request Forgery (SSRF) attacks.

The Sentry team has already released a patch with the latest version 7.77.0.

While we still recommend updating to the latest version of the Sentry SDK, Vercel has taken proactive measures on our firewall to protect our customers.

We will continue to proactively protect all Sentry + Next.js deployments on Vercel, regardless of Sentry's Next.js SDK version running.

Vercel Edge Config is our global low-latency data store for feature flags, experiments, and configuration metadata. Now, backups of your Edge Config are automatically created with every update to an Edge Config's items. You can restore backups from the Storage tab in your Vercel dashboard.

Customers on all plans can take advantage of backups. Hobby customers have 7 days of backup retention, Pro customers have 90 days of backup retention, and Enterprise customers have 365 days of backup retention.

Check out the documentation to learn more.

You will now see more information in the build logs when your build fails due to either exhausting the available memory (OOM) or disk space (ENOSPC).

In the case of OOM, your build logs will confirm the event. For ENOSPC situations, detailed information on disk space allocation is provided.
