Attention developers! This is our biggest refactor yet. With this release, we’ve made FreshJuice faster, easier to maintain, and better suited for advanced customization.

🚀 Major Changes

🎨 Rebranding & Version Bump

FreshJuice is now officially FreshJuice DEV (Developer Edition).
This name change reflects our focus on making the theme the perfect foundation for developers building HubSpot sites.
We’ve updated the repository structure, build scripts, and all internal references.
The version has been bumped to v3.0.0 to mark these breaking changes.

🆙 TailwindCSS Upgrade to v4.0.0

One of the most important changes: we’ve upgraded TailwindCSS from v3.x to v4.0.0.
This brings:

Zero-config setup — tailwind.config.js is no longer required by default.
Built-in JIT mode and automatic class scanning.
More optimized CSS output out of the box.

⚠️ Breaking change: If you had custom Tailwind configuration, check out the
Tailwind v4 Migration Guide before updating.

💅 CSS & UI Improvements

Removed the fj- prefix from all CSS classes for a cleaner, more consistent naming convention.
Added new CSS utilities for margins, text colors, and hover effects.
Improved styling consistency across multiple modules.

⚙️ JavaScript Enhancements

Improved MutationObserver to better handle DOM changes and remove nodes efficiently.
Added helper functions isCheckbox and isRadio for cleaner, reusable code.
Refined initTree and destroyTree logic for better DOM manipulation and memory management.

🧹 Cleanup & Dependencies

Removed unused configuration files: tailwind.config.js and postcss.config.js.
Updated dependencies in package.json and package-lock.json.
Bumped esbuild to 0.25.9.
Updated Node.js prerequisite to v22.0.0.
