TL;DR

Fresh now supports the View Transitions API (modern browser navigation) and WebSockets, enabling richer, more interactive web applications.

New

• WebSockets: Add real-time communication to your applications using ctx.upgrade() and app.ws() (bidirectional communication).
• View Transitions API: Enable smoother, animated page transitions in supporting browsers (client-side navigation).
• Project Initialization: Use deno create to quickly scaffold new Fresh projects (command-line tool).

Fixes Worth Knowing

• Improved compatibility with npm packages via a better CJS-to-ESM transform.
• Fixed issues with CSS modules and static file paths.
• Corrected handling of active links with query parameters.
• Resolved issues with Vite asset caching and base path configuration.

Before You Upgrade

If you rely on Babel for CJS transforms, be aware that the Babel transform was briefly reverted and is now re-enabled. No action is needed, but be aware of this change if you encountered issues with CJS compatibility in 2.3.3.

TL;DR

Fresh now fully supports Deno 2, resolving issues with the esbuild-deno-loader (a fast JavaScript bundler) and its caching mechanism.

Fixes Worth Knowing

Resolved an issue where esbuild-deno-loader didn’t work correctly with Deno 2’s new file caching.

TL;DR

Fresh now supports internationalization (i18n) allowing you to configure the language for your web application.

Fixes Worth Knowing

Restarting the development server no longer causes multiple reloads. Favicons are now generated correctly when initializing a new project. Mobile zoom issues in the counter example have been resolved.

Before You Upgrade

Ensure you are using a Deno version that meets the minimum requirements checked during project initialization.
