We've released the final update to the build-tools-ci Docker image. We will not publish any further updates, bug fixes, or security patches to the following tags:

  • pantheonpublic/build-tools-ci:9.x-php8.2
  • pantheonpublic/build-tools-ci:9.x-php8.3
  • pantheonpublic/build-tools-ci:9.x-php8.4
  • quay.io/pantheon-public/build-tools-ci:9.x-php8.2
  • quay.io/pantheon-public/build-tools-ci:9.x-php8.3
  • quay.io/pantheon-public/build-tools-ci:9.x-php8.4

Background

These base images were created at a time when CI providers recommend using customized Docker images to speed up execution and reduce the need for replicating boilerplate configration. It has since become more common to run CI jobs on standard base images for speed and the reduction in boilerplate code comes from reusable GitHub Actions or CircleCI Orbs.

Recommended migration

Use a standard base image from your CI provider and install the Pantheon tools you need during the CI run. Standard images are better cached by CI runners, so your pipelines will perform better overall than with a custom image.

Learn more about Pantheon's reusable GitHub Actions and CircleCI Orb.

Action required

If you use any of the build-tools-ci image tags listed above, migrate to a standard base image before the included dependencies become outdated.

April 7, 2026

Solr support for WordPress and the Solr Power plugin will reach end of life on January 11, 2027. After this date, Solr-based search will no longer be available for WordPress sites on the platform.

What's changing?

Solr 3 is a legacy search technology that is being retired in favor of modern alternatives. Sites currently using Solr 3 with the Solr Power plugin will need to migrate to a supported search solution before the end-of-life date.

Recommended alternatives

Pantheon customers

We recommend migrating to Elasticsearch, now available as a Beta add-on for WordPress sites on Pantheon. Elasticsearch offers improved search relevance, real-time search-as-you-type, WooCommerce support, and more. See the Elasticsearch for WordPress Beta announcement for details.

Other options

If Elasticsearch is not the right fit for your site, consider these third-party search solutions:

  • SearchWP — A WordPress-native search plugin that enhances the default WordPress search without requiring an external search service.
  • Algolia Search — A hosted search API that provides fast, relevant search results with advanced features like typo tolerance and faceted filtering.

What you need to do

  1. Identify any WordPress sites currently using the Solr Power plugin.
  2. Choose a replacement search solution.
  3. Complete your migration before January 11, 2027.
