Greptile Overview

Greptile Summary

This PR upgrades Next.js from version 15.5.10 to 16.1.5, a major version bump that includes critical security patches for CVE-2025-59471, CVE-2025-59472, and CVE-2026-23864.

Key Changes:

• Updated Next.js dependency from ^15.5.9 to ^16.1.5 in the nextjs-example app
• Updated pnpm-lock.yaml with new dependency resolution and platform-specific SWC binaries
• Removed unused Next.js 15.5.7 platform artifacts

Security Improvements:

• Addresses DoS mitigation for React Flight
• Adds maximum size limit for postponed body parsing
• Reduces next/image maximum response body from 300MB to 50MB

Compatibility Notes:

• The example app uses App Router with route handlers (/api/webhooks/*)
• React 19 is already in use, which is compatible with Next.js 16
• The next.config.js has minimal configuration with empty experimental options

Confidence Score: 4/5

• This PR is safe to merge after verifying that builds and tests pass
• Score reflects the automated dependency update with critical security patches. The major version bump from 15 to 16 requires testing to ensure compatibility, particularly for the webhook route handlers, but the minimal Next.js configuration and straightforward App Router usage reduce risk.
• No files require special attention - this is a standard dependency update
