Next.js 16 is now the default version for new site creation on Pantheon. When creating a new Next.js site, you will automatically get Next.js 16, the latest version of the leading React framework for building web applications.

What's New

Next.js 16 introduces Cache Components, moving the framework further in the direction of "dynamic by default" architecture. Pantheon's horizontally scalable container infrastructure with shared caches is well-suited to support this direction.

Creating New Sites

When you create a new Next.js site, it will default to Next.js 16. You can create sites via Terminus:

You can also create Next.js sites through the Pantheon Dashboard, which will automatically use Next.js 16.

Additional Information

For more details about Next.js on Pantheon, see our Next.js documentation.

Content Publisher now includes a quality assistant — an intelligent review system that helps you create better content before you publish. Starting with accessibility checking at no added cost, the quality assistant will expand to help ensure your content meets brand standards, performs well in search, and satisfies compliance requirements.

What’s new?

The quality assistant's automatic accessibility checking helps catch common issues before you publish:

  • Missing alt text on images
  • Improper heading hierarchy
  • Non-descriptive link text
  • and more...

Issues are displayed in the sidebar with plain-language descriptions of the problem, why it affects users with disabilities, how to fix it, and where it occurs in your document.

The @pantheon-systems/nextjs-cache-handler package is now publicly available. It enables persistent caching on Pantheon's Next.js platform, so your cached data survives across deployments and server restarts.

Features

  • Works out of the box on Pantheon — The handler auto-detects your environment. No extra configuration needed beyond installing the handler in your Next.js application.
  • Full support for Next.js caching APIsrevalidateTag(), revalidatePath(), and ISR work as expected, including automatic CDN cache invalidation so your visitors see updates immediately.
  • Next.js 16 use cache support — Compatible with the new cacheHandlers API and 'use cache' directive introduced in Next.js 16.
  • Smart build deploys — When you deploy a new build, page caches refresh automatically while your data caches are preserved, avoiding unnecessary re-fetches from APIs and databases.
  • Local development friendly — Uses file-based caching in development so you can test caching behavior locally without any cloud dependencies.
  • Debug logging — Set CACHE_DEBUG=true to see detailed cache hit/miss/set activity for troubleshooting.

Getting started

Install the package:

Then configure your Next.js application to use the cache handler. For full setup instructions, usage examples, and configuration options, see the README on GitHub.

PHP version 8.4.18 is now available on the platform. This update includes bug fixes and enhancements that improve performance and stability. Updates will be applied automatically over the next few days, so no manual action is required.

We’ve updated the Top Traffic Patterns interface, located in the Metrics tab of your Live environment dashboard, to give you deeper visibility into your site's traffic. You can now see the exact request count alongside each of the metrics IPs, User Agents, and Paths.

By surfacing the exact volume of requests, it is much easier to measure the true impact of specific actors or pages. These counts help you confidently decide if an aggressive scraper warrants being blocked, or exactly how much load a highly visited path is handling so you can accurately prioritize your caching and optimization efforts.

Note: The Top Traffic Patterns feature is in active, iterative development. You can expect frequent updates and new enhancements in the near future.

We have released version 0.8.0 and version 0.9.0 of the 'Push to Pantheon' GitHub Action.

What's new in 0.8.0?

Version 0.8.0 adds several new features and improvements to the GitHub Action.

  • Git-only deployment - You can now deploy directly to Pantheon using Git push without requiring Terminus Build Tools. Set skip_build_tools: true to use this lightweight deployment option, which is ideal for brand-new sites or workflows that don't need database or file syncing.
  • Automatic Build Tools fallback - The action now automatically falls back to Git-only mode when Build Tools operations fail, ensuring deployments succeed even when the Build Tools plugin encounters issues. This fixes a failure mode where deploys would fail if a site did not yet have a Live environment initialized.
  • Multidev limit checking - The action now checks if you've reached Pantheon's multidev limit before attempting to create environments, providing clear error messages when limits are reached instead of cryptic failures.
  • GitHub permission validation - New pre-flight permission checks validate that your GITHUB_TOKEN has the required scopes before starting deployments, with helpful error messages explaining how to fix missing permissions.
  • Build Tools version selection - You can now choose which version of the Terminus Build Tools plugin to install using the build_tools_version input parameter. This gives you control over plugin compatibility and allows testing development versions if a particular Build Tools version or branch is required.

What's new in 0.9.0?

Version 0.9.0 adds a number of under-the-hood improvements and moves much of the scripting logic out of the action.yml file and into a new main.sh file. This makes the action easier to maintain and test, and also allows for more complex logic that would be difficult to implement directly in the action.yml file.

Additionally, version 0.9.0 adds comprehensive unit and integration tests for the actions logic and deployment workflows, improving the reliability and stability of the action. The new testing framework also allows for easier debugging and faster development of new features in the future.

For more details and a full list of changes in these releases, please refer to the 0.8.0 release notes and 0.9.0 release notes.

To update to the latest version, modify your workflow file to use 0.9.0:
