<blockquote>
<h1>Release rayon 1.8.1 / rayon-core 1.12.1 (2024-01-17)</h1>
<ul>
<li>The new <code>&quot;web_spin_lock&quot;</code> crate feature makes
mutexes spin on the main
browser thread in WebAssembly, rather than suffer an error about
forbidden
<code>atomics.wait</code> if they were to block in that context. Thanks
