What is a Release Candidate?

A Release Candidate is the final pre-release stage in our development cycle. All planned features are in place, and the focus has fully shifted to quality, stability, and catching any remaining regressions. RC1 is functionally what we intend to ship as the final 9.1 release. Any fixes applied from this point on will be based directly on your reports.

What’s inside PrestaShop 9.1 RC1?

All the features introduced during the beta phase are included. Here’s a quick recap of the highlights:

Hummingbird 2.0: new default theme

Hummingbird 2 is now the default theme in PrestaShop 9.1. Built on Bootstrap 5, it prioritizes performance, developer experience, and accessibility, achieving over 95% compliance with the European Accessibility Act (EAA).

Tech overview Release notes Discussions & feedback

Multi-carrier / Multi-shipping

PrestaShop 9.1 introduces shipment-based order management, giving merchants the ability to split and merge shipments within a single order. This removes the long-standing “1 order = 1 carrier” limitation and improves clarity for both merchants and customers.

Note: this feature is behind a feature flag.

How to test PrestaShop 9.1 RC1

This is a pre-release version. Do not install it on a production shop. Test it in a dedicated staging or development environment only.

Download PrestaShop 9.1 RC1

  1. Download and install RC1 in a test or staging environment (never on a live shop).
  2. Enable the relevant feature flags to test experimental capabilities.
  3. Test your themes, modules, and customizations for compatibility.
  4. Report any bugs or regressions on GitHub with clear reproduction steps.

Requirements for PrestaShop 9.1 RC1

  • PHP 8.1 (up to PHP 8.5 is supported)
  • Composer 2
  • Node.js 20 and NPM 10

Please check all system requirements in the documentation. You must also have Git installed on your machine.

Creating a custom ZIP

If you prefer not to use the Classic version, you can build a custom ZIP file with the PrestaShop Release Creation tool:

  1. Clone the repository using the 9.1.0-rc.1 tag: git clone [email protected]:PrestaShop/PrestaShop.git --branch "9.1.0-rc.1" .
  2. Run composer create-release or php tools/build/CreateRelease.php in the root of the repository.
  3. The ZIP file will be generated in the tools/build/releases/ directory.

Known limitations

No upgrade path

You cannot upgrade from Beta to RC1, nor from RC1 to the final release using the Update Assistant module. Always use a fresh installation for testing pre-release versions.

Do not install on live shops. This version may still contain bugs. It is intended for testing purposes only.

Your feedback matters

RC1 is the last major checkpoint before the final release, and your testing during this window directly shapes the quality of what ships. There’s no beta cycle left. Only your reports between now and the final release.

Here is how you can help:

  1. Install RC1 in a dedicated test environment.
  2. Enable feature flags to verify the new functionality.
  3. Test your setup: themes, modules, integrations, and customizations.
  4. Report issues early via GitHub Issues, with environment details and reproduction steps.

You’re also welcome to discuss your findings in the GitHub Discussions or on Slack.
