Pantheon release notes

Your destination for staying informed about our latest innovations and product updates.
April 10, 2024

The latest version of WordPress, 6.5.2, became available on Pantheon as of April 10, 2024.

Highlights

What happened to 6.5.1?

6.5.2 is the first minor release for WordPress 6.5 rather than 6.5.1. Yesterday, it was disclosed on the Make WordPress Core development site that due to an error with the initial package, 6.5.1 could not be released.

Upgrade to WordPress 6.5.2 right from your Pantheon dashboard or Terminus for added security.

April 3, 2024

We are thrilled to announce that on April 23, 2024, we will upgrade the New Relic PHP agent to the latest version (v10.19.0.9). This update is part of our ongoing commitment to enhancing your experience with Pantheon and ensuring that our offerings meet your evolving needs.

By staying up-to-date with the latest agent, you will benefit from improved performance and enhanced troubleshooting capabilities for your WordPress and Drupal instances. This means smoother experiences for your site visitors and more efficient workflows for you. This new version also fully supports PHP 8.3, providing you with the latest features and compatibility.

Learn More about New Relic®, real-time performance monitoring for your Pantheon web applications.

Action Required: Default behavior of New Relic Drupal Hooks is changing

After the release of this agent update, Pantheon will no longer support Drupal Hooks reporting by default. However, the functionality is still available. If this is crucial for troubleshooting your sites, please add these lines to your site’s pantheon.yml file to enable this reporting:

new_relic:
  drupal_hooks: true

The parameter above will take effect when the New Relic PHP agent is updated for your site.

If your site currently reports Drupal Hooks information to New Relic, you will need to add the above line to your pantheon.yml file before the April 23 update to maintain this reporting moving forward.

Our support team is happy to help if you have any questions or need assistance.

April 2, 2024

The latest version of WordPress, 6.5 (Regina), became available on Pantheon as of April 2, 2024.

Highlights

Font Library
  • WordPress 6.5 introduces the new Font Library. This feature allows you to upload fonts to your WordPress site or install any of the fonts available from Google's font library.
  • Previously, in version 1.3.3 of our Pantheon MU Plugin, we added support for the new Font Library feature by explicitly defining where fonts are stored to support this new feature.
  • For more information, refer to our documentation.
Interactivity API
  • WordPress 6.5 also adds a new Interactivity API. This API establishes a standardized way to add interactive elements to Gutenberg blocks.
Performant Translations
  • A new localization system has been introduced in WordPress 6.5 to improve the performance of translations. This system uses a new file format, .l10n.php, to store translations in addition to the standard .mo and .po files you may already be familiar with. When .l10n.php files exist, they are loaded instead, providing significant performance improvements and using less memory.
  • For more information about Performant Translations on Pantheon and how to generate .l10n.php files if they do not exist, see our Performant Translations guide.
Plugin Dependencies
  • WordPress plugins can now have dependencies on other plugins. This allows plugin authors to specify that their plugin requires another plugin to be installed and activated in order to work properly. A new Requires Plugins Plugin Header has been introduced to require other plugins to be installed and activated before the current plugin can be activated and prevent plugins that are dependent upon other plugins to be deactivated accidentally. For more information, see the Plugin Dependencies dev note.

What is changing?

Great news! Pantheon is simplifying the way we calculate and apply site visit overages. This change will help reduce excess billing and unplanned costs should a site exceed its plan limits.

This change is effective for site visits on or after January 1, 2024. In order to transition to the new overages model and allow you, the customer, to digest this change Pantheon will not run an overages process in February 2024. This new program will be formally launched in March 2024 and the initial month’s processing will encompass usage from January and February of 2024.

The new overage charge policy

Effective for usage starting on January 1, 2024, overages will be billed $40 for each 10,000 unique site visits (a unique site visit is defined as a specific IP address and user agent combination over a 24-hour period) or portion thereof that exceeds the amount of included unique visits in the subscription. This applies uniformly to all sites running on the platform at all subscription levels.

In addition, with Overage Protection, all Pantheon customers, except for Basic plans and monthly subscriptions, will have one month of overages waived every 12 months during the subscription term. For simplicity, the 12-month period will follow a calendar year running from January through December. This Overage Protection will be applied automatically on the first month of each plan year where your site is over the included unique visits in the subscription- you do not have to do a thing.

Lastly, for new customers coming onto the platform for the first time there will be a three-month grace period starting with your service start date (the day a site is first moved from a Sandbox to a commercial plan) where no overages will be incurred. This allows you the time to get calibrated on the platform and focus on what is most important: the successful launch of your web site(s) on Pantheon!

The prior overage charge policy

Prior to this change, if a site exceeded the unique site visits included in the subscription plan, the plan would be automatically upgraded to a higher plan level that was a better fit for the amount of unique site visits. Many times that increase would result in a surprise to customers, who hadn’t budgeted for increasing the plan for the remainder of the subscription term, and the cost would be more than what customers thought was fair. We listened, and we’re making this change to make Pantheon a brand you trust even more.

Will you show me an example of how this works?

Example scenario

Assume you purchase an annual Performance Small plan that includes 25,000 unique monthly site visits starting October 1st. The cost of a Performance Small plan is $160 per month (paid annually). Note that the next plan level up is a Performance Medium plan that includes 50,000 unique monthly site visits is $275 per month (paid annually).

During the holiday season, you have 40,000 unique site visits in November and 45,000 in December, before returning to less than 25,000 monthly unique site visits during the rest of your contract term (Jan-Sep).

Dataset for example overage scenario

Overage fee under the new policy

Under the new policy, you will simply pay a one-time fee of: $ 0 for November’s extra 15,000 visits because Overage Protection allows 1 free month of overages, and $ 80 for December’s extra 20,000 visits.

Overage fee under the old policy

Because you exceeded the plan limits of 25,000 for two consecutive months, under the old policy your plan would have been automatically upgraded to the Performance Medium plan starting in December. This would have increased your monthly cost from $160 to $275 a month, or an additional $115 per month. Since the plan change occurred in December and you still had 9 months remaining on your term, this increase would have cost $1,035 extra, which would be charged to your credit card in January or you would have received an additional invoice for plans on contract.

Comparison of the new vs. old overage fee

As you can see in this example, the new overage fee is a total of $80 vs. the cost for the upgraded plan under the prior policy would have increased your cost $1,035 –- the new policy saves you 92%!

Chart comparing price difference between the old policy and new policy

Updated documentation

We've updated our Overage Policy documentation to align with the new policy and provide more specifics, such as additional benefits for new site launches and qualifying nonprofit organizations.

March 27, 2024

On March 25, 2024, it was announced in the WordPress development blog that the default storage location for the Font Library (added in WordPress 6.5) will be wp-content/uploads/fonts. Previously, we had added a feature to our Pantheon MU Plugin to support the new Font Library feature by changing the previous default path (wp-content/fonts) to wp-content/uploads/fonts. This change to our MU plugin removes that override as it is no longer necessary. You can read more about the Font Library feature in our guide to using the Font Library on Pantheon.

March 26, 2024

We've updated our Terminus GitHub Action with the ability to share sessions across jobs to simplify and reduce the authentication overhead including any associated rate limiting when authenticating their machine token. These sessions are encrypted prior to being cached using industry standard AES-256 encryption, PBKDF2 (Password-Based Key Derivation Function 2) algorithm, and increased iterations when deriving the encryption key. We've also updated to the latest versions of actions/checkout and actions/cache.

Some technical details:

  • The session data is encrypted using OpenSSL with AES-256 and PBKDF2 before being cached.

  • The session information is scoped to a workflow run, meaning re-running the same workflow will use existing cache (in case of a failure, etc) while new workflows create a new session.

March 20, 2024

As part of our continued effort to provide the latest and best in secure software, PHP versions 7.1 and below will reach end-of-sale (EoS) on May 15, 2024. This means that sites created after May 15 will not be able to change their PHP version to PHP 7.1, 7.0, or any version of PHP 5. Sites created with custom upstreams using EoS PHP may also have unexpected behavior upon site creation.

Sites already running PHP 5, PHP 7.0, or PHP 7.1 will continue to run even after May 15.

PHP 7.1 was declared end-of-life (EoL) by the PHP Foundation on November 30, 2020, more than three years ago. PHP 5.6 reached EoL on December 31, 2018, more than five years ago. EoL software does not receive security or feature updates, and could expose sites to attack if any vulnerabilities or exploits are discovered.

Action required

Customers using custom upstreams with a PHP version less than 7.2 should update their custom upstreams by May 15 to avoid disruption. The current supported versions of PHP are 8.1, 8.2, and 8.3. Pantheon currently recommends at least PHP 8.1 for all production sites.

March 18, 2024

PHP 8.2.17 and 8.3.4 were released on the platform. They contain the latest bug fixes and security releases for PHP. As a reminder, PHP 8.0 reached End-of-Life on 26 November 2023. For the best performance and security, Pantheon recommends running PHP 8.1 and above.

March 11, 2024

Pantheon Advanced Page Cache v1.5.0 is now available on WordPress.org and GitHub. This release adds a new filter to make cache purges less aggressive and provide more flexibility for developers and the sites they maintain. You can learn about the filter in the plugin's README file which includes an example of how to use it.

Additionally, this update implements our recently updated WPUnit Helpers project to simplify PHP Unit tests as well as our recently developed Plugin Release Actions to automate steps in the release process.

You can read the full changelog in the GitHub release notes.

March 8, 2024

The latest version of Drupal 7, 7.100, became available on Pantheon as of March 8, 2024.

Highlights

  • Announcements Module 7.100 includes the Annoucements module backported to Drupal 7. Please read the change record before updating if you do not want the module to be automatically enabled.
  • PHP 8 Compatibility Bundled with Drupal 7's release is an update to Pantheon's Apache Solr module that fixes deprecation warnings with PHP 8.1+.
  • Bug fixes and security hardening In addition to the Announcements module, the release includes a few bug fixes and feature improvements. No security fixes are included in this release. For full details, see the release notes on Drupal.org.

Upgrade your Drupal 7 site to Drupal 7.100 right from your Pantheon dashboard or Terminus.

March 4, 2024

WordPress 6.5 will add a new Font Library feature. The Font Library allows you to upload fonts from your computer or add any of the fonts available on Google's font library to your WordPress site. In anticipation of this, Pantheon has added a feature to our Pantheon MU Plugin to support the new Font Library feature. You can read more about the Font Library feature in our guide to using the Font Library on Pantheon.

February 27, 2024

We've recently modified the Pantheon wrapper around the WP-CLI executable to solve a number of interrelated issues that customers may have previously been experiencing and/or using workarounds to solve. We recommend reviewing your site's logs and resolve any PHP notices or warnings.

Problem

  • Our WP-CLI wrapper included a hard-coded --url flag for all wp commands run on the platform (via Terminus, e.g. terminus remote:wp or terminus wp, or internal workflows that relied on WP-CLI like flushing cache or viewing the Status page in the dashboard).
  • For WordPress Multisites, the hard-coded --url flag pointed to the Pantheon platform domain (*.pantheonsite.io) instead of the actual domain of the site resulting in errors and the command failing unless executed manually (via Terminus with the correct --url flag attached).

Solution

  • We have implemented a solution that checks if a site is a WordPress Multisite. If so, we remove the hard-coded --url flag, allowing WP-CLI to operate normally.
  • This change does not affect workflows that are properly passing the --url flag to WP-CLI commands via terminus (e.g. terminus wp <site>.<env> -- plugin list --url=<url>). Any WP-CLI flags passed after the -- in the terminus wp command will be passed through to and interpreted by WP-CLI.
  • This change means that many sites that were previously unable to view their full Status page will now be able to do so, and flushing site cache via the button in the Pantheon dashboard on sites that previously were unable to or had errors in doing so should now work as expected. Any other workflows or processes that relied on WP-CLI will also benefit from this change.

Recommended action

This change may also expose PHP notices and warnings that were previously being hidden due to WP-CLI failing commands. We recommend reviewing your site's logs and working to resolve any PHP notices or warnings that you see.
February 21, 2024

The latest versions of PHP 8.x are now available on the Pantheon platform. PHP 8.1.27, 8.2.16, and 8.3.3 are all bug fix releases. No action is required on your part if you are using one of these PHP versions (8.1, 8.2 or 8.3).

February 20, 2024

Administrators of large workspaces will now be able to easily remove access for offboarded users at scale. When a member of your team changes jobs, or for whatever reason you need to remove a person from your sites, you can now do so faster

As you remove users from your workspace or site team, you will be prompted to remove access across all sites that a given user may be connected to, which can save multiple clicks and manual labor to ensure the right access levels are maintained.

To learn more about how this new offboarding process works, take a look at our documentation.

November 1, 2023

Pantheon introduced a new build pipeline for Front End Sites to significantly improve build times. Beginning on November 13th, 2023, newly created sites are automatically using the new pipeline and cannot opt back to the old pipeline. Sites made prior to that date can opt-in to the new pipeline to take advantage of the new features. All pre-existing sites that do not opt-in will be switched over for new builds on or around January 15th.

Additionally, we are adding support for Node 18 (for dynamic sites) and 20 (for both static and dynamic sites). To select a specific version, Pantheon is moving away from using .nvmrc and will instead look to the “engines” field in your project’s package.json file.

To find out more about adopting the new pipeline, check out our documentation, and read our blog post about how we’re already experiencing the benefits of this internally at Pantheon.

November 1, 2023

The File System team at Pantheon achieved significant speed improvements in backup processes. The Valhalla export process was overhauled, allowing backups to be constructed from new objects, cutting down export times by 25-83%. This was accomplished by initiating object retrieval immediately after receiving MANIFEST metadata, omitting empty files, and promptly archiving received files.

We released an update for the Solr Search for WordPress plugin which disables auto-commit by default and allows cron to push solr commits regularly instead.

This drastically improves the performance of large sites and avoids 503 errors related to hard committing on every update. This update is recommended for all WordPress sites currently running the plugin.

You can still enable auto-commit by explicitly setting SOLRPOWER_DISABLE_AUTOCOMMIT to false.

September 1, 2023

Pantheon has deployed PHP versions 8.2.9, 8.1.22, and 8.0.30 to customer sites running on the platform. These releases address vulnerabilities disclosed in CVE-2023-3823 and CVE-2023-3824.

If you are using PHP 8.2, 8.1 or 8.0, there is nothing further that you need to do. If you are still on PHP 7.4 or earlier, though, you should schedule some time to upgrade to a supported version.While the vulnerabilities patched in these latest releases are not reported to affect PHP 7.4, the fact remains that there could be (and probably are) unpatched vulnerabilities in the end-of-life versions. Read more about it in Greg Anderson’s blog post.

September 1, 2023

We released an update for the Pantheon Advanced Page Cache WordPress plugin which adds a filter to allow disabling surrogate keys for posts' taxonomy terms. This can be especially helpful for posts with large numbers of taxonomies (such as WooCommerce products with a large number of global attributes).

For more information, see Pantheon documentation.

Pantheon has pushed an update to WordPress and Drupal 7 core upstreams which sets PHP 8.1 as the new default PHP version, rather than 7.4.

Please test this core update thoroughly before deploying to the Live environment. If your site requires an older version of PHP, or if you'd like to upgrade to PHP 8.2, see Pantheon’s documentation on how to manage PHP versions via the pantheon.yml configuration file.

September 1, 2023

We released version 1.0.5 of the WP Decoupled Preview plugin which contains a bug fix specific to WordPress 6.3. WP Decoupled Preview enables content editors to see their changes in the context of a front-end framework (served through Pantheon's Front-End Sites) like Next.js. To try this functionality, request access to Front-End Sites and follow our tutorial for spinning up our WordPress + Next.js starter.

Can you tell we want more teams to sign up for Front-End Sites? If you don't yet have access, as of the last month you'll now see callouts in the site creation flow that lead to Front-End Sites Access:

Sign up page in the Pantheon dashboard for decoupled Early Access

Thanks to efforts in the last month, once you spin up new codebases in Front-End Sites, you will also find:

  • Newly improved readme files in your fresh projects.
  • Health checks that fire early in the build process if your Front-End Site may be likely to fail due to missing variables for a back-end CMS
  • A better navigation and search functionality for the Decoupled Kit project documentation.

In Pantheon's continual efforts to stay up to date with modern web security standards, Pantheon is removing support for a certain set of cipher suites for TLS 1.2.

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256
  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA

  • TLS_RSA_WITH_AES_128_CBC_SHA
  • TLS_RSA_WITH_AES_128_GCM_SHA256
  • TLS_RSA_WITH_AES_256_CBC_SHA

The Mass Update plugin applies all available upstream updates to a list of sites. This allows users who manage a lot of sites to easily stay on top of Drupal and WordPress core updates.

Build Tools

This Terminus plugin contains a collection of six additional commands useful during the build step on a Pantheon site that uses a GitHub PR workflow.

Filer

Terminus Filer is named as such because it’s an easy way to launch your SFTP client with all the connection details “filled” in.

Rsync

The Terminus Rsync Plugin makes it easy to copy files between your local computer and Pantheon. Once installed, you can use rsync as you normally would to transfer files, wrapped in Terminus commands.
