“Vite is now using Rollup 4, which already represents a big boost in build performance. And there are also new options to improve your dev server performance profile.”

“Vite 5 focuses on cleaning up the API (removing deprecated features) and streamlines several features closing long-standing issues, for example switching define to use proper AST replacements instead of regexes. We also continue to take steps to future-proof Vite (Node.js 18+ is now required, and the CommonJS Node API has been deprecated).”

“This release adds indentation back to nested ternaries along with a new --experimental-ternaries flag to try a more novel "curious ternary" format that scales better to deeply nested conditionals.” A separate blog post provides more information on --experimental-ternaries.

“We have also added support for the control flow syntax in Angular v17. For details on the syntax, please read the official Angular release post.”
