<blockquote>
<h1>Release rayon 1.5.2 / rayon-core 1.9.2 (2022-04-13)</h1>
<ul>
<li>The new <code>ParallelSlice::par_rchunks()</code> and <code>par_rchunks_exact()</code> iterate
slice chunks in reverse, aligned the against the end of the slice if the
length is not a perfect multiple of the chunk size. The new
<code>ParallelSliceMut::par_rchunks_mut()</code> and <code>par_rchunks_exact_mut()</code> are the
same for mutable slices.</li>
<li>The <code>ParallelIterator::try_*</code> methods now support <code>std::ops::ControlFlow</code> and
<code>std::task::Poll</code> items, mirroring the unstable <code>Try</code> implementations in the
standard library.</li>
<li>The <code>ParallelString</code> pattern-based methods now support <code>&amp;[char]</code> patterns,
which match when any character in that slice is found in the string.</li>
<li>A soft limit is now enforced on the number of threads allowed in a single
thread pool, respecting internal bit limits that already existed. The current
maximum is publicly available from the new function <code>max_num_threads()</code>.</li>
<li>Fixed several Stacked Borrow and provenance issues found by <code>cargo miri</code>.</li>
</ul>
