You can now create Vercel Blob stores in any of the 19 Vercel Regions.

Selecting a region closer to your Functions and users allows you to optimize upload speed and comply with data-residency requirements when required.

Selecting a region is available at creation time in the Vercel dashboard or when using the Vercel CLI (version 44.3.0).

Learn more about Vercel Blob in the documentation.

You can now control Vercel’s Web Application Firewall (WAF) actions directly in vercel.json, alongside existing support in the dashboard, API, and terraform.

The has and missing matchers have also been enhanced to support more expressive conditions across headers, rewrites, redirects, and routes. Matching options include:

• String equality and inequality

• Regular expressions

• Prefixes and suffixes

• Inclusion and exclusion from string arrays

• Numeric comparisons

The following example shows how to deny a request that is prefixed by a specific header:

{
  "$schema": "https://openapi.vercel.sh/vercel.json",
  "routes": [
    {
      "src": "/(.*)",
      "has": [
        {
          "type": "header",
          "key": {
            "pre": "x-bad-header-"
          }
        }
      ],
      "mitigate": {
        "action": "deny"
      }
    }
  ]
}

The v0 Platform API is now available in public beta. The v0 Platform API is a text-to-app API — it provides programmatic access to v0’s app generation pipeline:

• Generating code for web apps from prompts

• Structured parsing of generated code

• Automatic error fixing

• Link with a rendered preview

This API also supports programmatic control of v0.dev, including creating and managing both chats and projects. We'll be bringing more of v0.dev's functionality into the Platform API soon.

The v0 Platform API is designed for integration into development workflows, automation scripts, and third-party tools.
