<blockquote>
<h2>plugin-react@4.2.0</h2>
<h3>Update peer dependency range to target Vite 5</h3>
<p>There were no breaking change that impacted this plugin, so any
combination of React plugins and Vite core version will work.</p>
<h3>Align jsx runtime for optimized dependencies</h3>
<p>This will only affect people using internal libraries that contains
untranspiled JSX. This change aligns the optimizer with the source code
and avoid issues when the published source don't have <code>React</code>
in the scope.</p>
<p>Reminder: While being partially supported in Vite, publishing TS
&amp; JSX outside of internal libraries is highly discouraged.</p>
<h2>plugin-react-swc@4.2.0</h2>
<h3>Add <code>@vitejs/plugin-react-swc/preamble</code> virtual module
for SSR HMR (<a
href="https://redirect.github.com/vitejs/vite-plugin-react/pull/890">#890</a>)</h3>
<p>SSR applications can now initialize HMR runtime by importing
<code>@vitejs/plugin-react-swc/preamble</code> at the top of their
client entry instead of manually calling
<code>transformIndexHtml</code>. This simplifies SSR setup for
applications that don't use the <code>transformIndexHtml</code> API.</p>
<h3>Use SWC when useAtYourOwnRisk_mutateSwcOptions is provided (<a
href="https://redirect.github.com/vitejs/vite-plugin-react/pull/951">#951</a>)</h3>
<p>Previously, this plugin did not use SWC if plugins were not provided
even if <code>useAtYourOwnRisk_mutateSwcOptions</code> was provided.
This is now fixed.</p>
<h2>plugin-react@4.1.1</h2>
<ul>
<li>Enable retainLines to get correct line numbers for jsxDev (fix <a
href="https://redirect.github.com/vitejs/vite-plugin-react/issues/235">#235</a>)</li>
