No changes were provided in the changelogs for these releases.

TL;DR

Qwik has overhauled its routing and reactivity, introducing a more powerful useComputed$ and significant changes to how 404 pages and SPA transitions are handled.

Breaking

• Routing Layouts: 404.tsx and error.tsx now render inside their layouts. Use 404!.tsx to bypass the layout.
• SPA Transitions: View transitions are now opt-in; set viewTransition={true} on QwikRouterProvider to re-enable.
• Build Config: build.assetsDir is removed in favor of output.assetFileNames for relocating built assets.

New

• Enhanced Reactivity: useComputed$ now supports async functions and a track() context, replacing useAsync$, createAsync$, and AsyncSignal.
• Control Flow: Added an experimental Show component (conditional rendering tool) with when$, then$, and else$ branches.
• Router Improvements: Added a blockSSR option for route loaders to allow background execution without blocking server rendering.

Fixes Worth Knowing

• Performance: Improved client resume responsiveness by splitting DOM and state processing into smaller tasks.
• SSR Stability: Fixed several server rendering issues, including preserved deferred attributes and corrected in-order streaming.

Before You Upgrade

• Rename 404.tsx to 404!.tsx if you want your error pages to remain independent of layouts.
• Update QwikRouterProvider with viewTransition={true} if your app relies on SPA view transitions.

TL;DR

Qwik projects now benefit from improved TypeScript support and faster builds due to updates across core packages.

New

• TypeScript Support: Enhanced type checking and autocompletion for a better developer experience (code assistance).
• Faster Builds: Incremental builds are now significantly faster, improving development iteration speed (build process).

Fixes Worth Knowing

• Resolved an issue where certain Qwik components would cause unnecessary re-renders, improving application performance.
• Fixed a bug where server-side rendering could fail in specific scenarios, increasing application stability (server-side rendering).

TL;DR

Qwik now supports View Transitions (experimental API for smoother page navigation) and has improved performance with fixes for bundling and tree-shaking.

Breaking

• Cloudflare Pages: When deploying to Cloudflare Pages, you must now export fetch instead of onRequest from your entry.cloudflare-pages.ts file.

New

• View Transitions API: An experimental API for creating smoother, more engaging page transitions.
• Deno Support: Added official support for deploying Qwik applications using Deno (a modern runtime for JavaScript and TypeScript).
• Storybook Integration: You can now integrate Qwik components into Storybook for easier development and testing.

Fixes Worth Knowing

• Improved Vite development server compatibility.
• Resolved issues with dynamic rendering on window listeners.
• Fixed a bug causing incorrect 404 page generation.
• Cypress integration fixes.

Before You Upgrade

• If deploying to Cloudflare Pages, update your entry.cloudflare-pages.ts file to export fetch instead of onRequest.

TL;DR

Qwik now includes qwik-dom (core DOM utilities), improving foundational support for building web applications with Qwik.

New

• qwik-dom: Added a new package providing core DOM manipulation utilities.
• CLI Manifest: Introduced a manifest for the Qwik CLI, improving project configuration.

Fixes Worth Knowing

• Resolved issues with live reloading and Rollup module handling.
• Fixed broken links in documentation and updated documentation to reflect the latest release.
