🟡 (13:36) esbuild 0.28.1 changelog entry: fixes nested var declarations not correctly renamed during bundling (issue #4471); could cause name collisions when minification disabled

🟡 (13:36) esbuild 0.27.4 changelog entry: fixes CSS media query regression from 0.25.11 — or clause inside <media-condition-without-or> was not wrapped in parentheses (issues #4395, #4405, #4406)
🟡 (13:36) esbuild 0.27.4 changelog entry: fixes inject feature edge case (issue #4407) — inject file using export { jquery as 'window.jQuery' } can now always be rewritten as export { default as 'window.jQuery' } from 'jquery' without esbuild sometimes incorrectly generating an error
🔴 (13:36) User asserted: esbuild 0.27.4 inject fix means the following pattern can always be rewritten without esbuild sometimes incorrectly generating an error: import jquery from 'jquery'; export { jquery as 'window.jQuery' }; → export { default as 'window.jQuery' } from 'jquery';
