PrestaShop 9.1 Beta and Hummingbird v2

Tuto PrestaShop: PrestaShop 9.1 Beta and Hummingbird v2.

Discover PrestaShop 9.1 Beta launched on January 12, 2026, and dive into the heart of one of its three major new features: Hummingbird v2, the theme that redefines PrestaShop theme architecture and becomes the new standard from PrestaShop 9.1 onwards. A monumental project representing over 320 commits, 500 modified files, 50,000 additions, and 30,000 deletions of code lines.

Explore the developer-centric approach: unlike traditional themes, Hummingbird offers a structured, scalable, and modular foundation allowing developers and agencies to create and customize e-commerce stores with ease and efficiency, while remaining fully compatible with PrestaShop 9 and later versions.

Discover the modern technical stack that powers Hummingbird v2: complete adoption of Bootstrap 5.3.3 with exploitation of native components, transition to SCSS and TypeScript for more modernity and scalability, native dark mode support, and jQuery removal from the theme while maintaining compatibility for modules that still depend on it.

Master the optimized architecture and developer experience: modular and logical file structure facilitating code reading, extension, and maintenance, adoption of BEM (Block Element Modifier) methodology for non-Bootstrap components improving readability and reusability, and complete harmonization of styles and templates throughout the theme.

Benefit from performance, SEO, and accessibility optimizations: pre-optimization for Core Web Vitals ensuring fast loading, better interface and improved responsiveness, native lazy loading reducing resource usage, integrated SEO optimizations with JSON-LD structured data for better visibility, and compliance with over 95% of European Accessibility Act requirements. Average Lighthouse scores demonstrate excellent performance across all criteria.

Learn the best practices recommended by PrestaShop to fully leverage Hummingbird v2: maximum use of native Bootstrap components, optimal style management with CSS layers, and favoring data attributes over classes for JavaScript.

Identify essential attention points for migration: absence of jQuery in the theme, need to migrate from Bootstrap 4 to Bootstrap 5, and refactoring of native modules such as ps_mainmenu, ps_facetedsearch, ps_featuredproducts, and productcomments.

A complete and technical presentation to understand how Hummingbird v2 Beta marks a major turning point in the PrestaShop ecosystem and will become the new testing standard for Marketplace modules. Download, test, and participate in the evolution of this theme designed for modern web standards of 2026 and beyond.
