Hummingbird 2.0: the new default theme

The biggest change in PrestaShop 9.1 is that Hummingbird 2.0 is now the default front office theme. After months of development and community feedback since the beta, Hummingbird replaces Classic as the theme every new PrestaShop 9.1 installation ships with.

Hummingbird 2.0

Built for accessibility

With the European Accessibility Act (EAA) taking effect in June 2025, accessibility is no longer optional for online stores in the EU. Hummingbird 2.0 achieves over 95% compliance with the EAA requirements, giving merchants a strong head start toward meeting their obligations. Semantic HTML, proper ARIA attributes, keyboard navigation, and sufficient color contrast are built into the theme from the ground up.

Modern architecture for developers

Hummingbird 2.0 is a complete rebuild, not an incremental update to Classic. It brings:

  • Bootstrap 5 with LTS support for modern, consistent design components.
  • BEM-based CSS naming for easier maintenance and clearer structure.
  • SCSS architecture based on CSS @layer, enabling modular and scalable styling.
  • A reorganized directory structure that moves away from the legacy _dev layout.
  • Reduced third-party dependencies, favoring Bootstrap’s built-in components.
  • Clear separation between Bootstrap and PrestaShop-specific styles, simplifying custom overrides.
  • Native support for Bootstrap dark mode, which can be enabled via an SCSS variable.

Experimental features

PrestaShop 9.1 also ships with two experimental features, available behind feature flags. These features are still maturing and should be tested in non-production environments. Your feedback will help us refine them before they become the default in a future version.

What is a feature flag?

Feature flags let you enable experimental capabilities at your own pace. You can find them under Advanced Parameters > New & Experimental Features in your back office.

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.

Improved Discounts

The discount system has been redesigned around four types: Catalog, Cart, Free Shipping, and Free Gift. This replaces the legacy cart rules with a clearer and more performant structure.

Other notable improvements

Beyond the highlights above, PrestaShop 9.1 includes a large number of improvements across the platform.

New CLI commands

Three new console commands make it easier to manage your shop from the command line:

  • prestashop:thumbnails:regenerate to regenerate image thumbnails without going through the back office (#39478 by @iNem0o).
  • prestashop:search:index to trigger search indexation from the CLI (#39403 by @iNem0o).
  • prestashop:module:export-translations to export module translations into files (#39405 by @kpodemski).

PHP 8.5 support

PrestaShop 9.1 now supports PHP 8.1 through PHP 8.5, keeping the platform aligned with the latest PHP releases (#39211).

New hooks for module developers

Several new hooks give module developers more control over key moments in PrestaShop’s lifecycle:

  • actionUpdateDefaultCombinationAfter for reacting to default combination changes (#40720 by @Codencode).
  • Hooks on module enable, disable, and upgrade events (#38839 by @studiokiwik).
  • Hook on Configuration::updateValue to react to configuration changes (#38956 by @studiokiwik).
  • Hooks to control free shipping price calculations (#40730 by @Hlavtox).

Tags page migrated to Symfony

The Tags management page has been fully migrated to Symfony, including the grid, filters, create/edit forms, and bulk actions (#39516, #39649, #39977 by @Progi1984).

Performance and security

  • Significant cart performance improvement when a shop has many product combinations (#32058 by @MattKelvin).
  • Ajax controllers are now noindexed to prevent search engines from crawling internal endpoints (#38785 by @PululuK).
  • Two security vulnerabilities patched with the help of @clotairer from 202 ecommerce: stored XSS in back-office templates and improper use of validation framework (see PrestaShop 8.2.5 release for details).

Back office UX

Front office

  • Special characters are now allowed in search queries (#39433 by @MattKelvin).
  • Improved quantity input, add-to-cart button, and availability label behavior (#40538 by @Hlavtox).

Update to PrestaShop 9.1

If you are running PrestaShop 9.0.x, you will be able to update to 9.1 using the Update Assistant module. A compatible version of the Update Assistant is being finalized and will be available in the coming days. We will update this article once it is ready.

As with any update, we strongly recommend:

  1. Back up your shop (files and database) before starting.
  2. Test the update in a staging environment before applying it to your production shop.
  3. Review your modules and themes for compatibility with 9.1.

Important

If you were testing a pre-release version (Beta or RC1), you cannot upgrade from it to the final release using the Update Assistant. Please use a fresh installation instead.
