TL;DR

Qwik and Qwik City now provide more reliable server plugin loading and request handling, improving stability and diagnostics for developers.

Fixes Worth Knowing

• Request URLs are now normalized in Bun and Deno (JavaScript runtimes) to prevent unexpected behavior with protocol-relative paths.
• Server plugins are now sorted alphabetically, ensuring consistent loading order regardless of file system arrangement.
• getRequestEvent() provides access to the current request event, enabling better error reporting in starter templates.

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 projects now benefit from improved TypeScript support with enhanced static analysis, leading to fewer runtime errors and a better developer experience.

New

• Enhanced TypeScript support: Improved static analysis within Qwik applications (code checking) provides more accurate error detection during development.

Fixes Worth Knowing

• Resolved an issue where certain Qwik components would cause false-positive errors in TypeScript.
• Fixed a bug where the Qwik City (server routes) parser incorrectly handled dynamic imports.

TL;DR

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