What's New in P4 Code Review 2026.1

Released: March 2026

For a complete list of what’s new and bug fixes in this release, see the release notes.

Updated user interface for Test and Workflow configuration

To make it easier to configure workflows and associate tests with workflows, the user interface and documentation for the configuration of workflows and tests has been updated for improved usability.

In addition, the maximum length for test names and test messages has been increased from 80 to 1024 characters.

Email notification improvements

To make the subject line of email notifications more informative, you can configure the maximum length to be any value up to 260 characters or have no maximum length. See subject_crop_length in Example email configuration.

To avoid exposing code snippets in email notifications, see hideFileContent in Exclude code content from email review.

Copy the file path on the review page

With a single click on the "Copy file path" button, you can copy the path of a file on the review page. This allows you to paste the path wherever you want. To learn more, see Review version and common file path summary.

Automatic PHP upgrade to the minimum supported version

A package installation or upgrade automatically ensures that you have a supported version of PHP. To learn more, see Install and configure P4 Code Review from a package (recommended) or Upgrading P4 Code Review.

Improved readability for CMake

If you use CMAKE to build applications, syntax highlighting improves the readability of .cmake files. To learn more, see Supported syntax highlighting in the Review page.

Configure AI features with the user interface

Administrators can now configure AI features with an easy-to-use graphic user interface, which is more convenient and less prone to error than making edits the config.php file. To learn more, see Configure AI features.

If you want to programmatically manage this AI integration, RESTful endpoints are documented at Configurations: P4 Code Review configurations.
