# What's New in P4 Code Review 2025.2

Released: June 2025

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

## Helix Swarm is now P4 Code Review

Perforce has a new look and logo that reflects our place in DevOps workflows. As part of these changes, Helix Swarm is now P4 Code Review, highlighting its integration with P4 (formerly Helix Core) and its availability as part of the P4 Platform. Name updates and new icons to align with the P4 branding are in progress and will continue to roll out. To learn more, see Re-Introducing P4.

## AI code analysis enhancements

- Instead of sending an entire diff to an AI vendor for review, you can get more precise insights by selecting and submitting portions of your code. To learn more, see AI for code analysis.

- Get clearer and more readable feedback in AI vendor code review responses with new markdown formatting.

- Reduce the amount of stored data by automatically removing redundant AI code review responses. Set the duration for how long responses are stored. To learn more, see Set up a cron job to delete AI summaries.

- Integrate P4 Code Review with LM Studio. To learn more, see How to set up LM Studio integration for P4 Code Review.

## AI-powered search for product information

On the main page of the P4 Code Review documentation site, you can now enter a question to get an AI-generated answer. Optionally, you can filter your search by product. Answers combine content from the current version of the product documentation and the Perforce knowledge base. This new search experience helps you locate information more efficiently.

## Other enhancements

- To streamline email filtering, emails are filtered by reviewer role. The `use_cc_on_review_emails` configurable in the `mail` block in `config.php` file adds the required reviewers in the To field and optional reviewers to the Cc field. This feature is enabled by default. To revert to the previous behavior, see Filter review related emails.

- Added support for P4 API for PHP 2025.1, enabling full support for PHP 8.4.

- Added support for P4 Server 2025.1.
