changelog</a>.</em></p>
<blockquote>
<h1>0.23.0</h1>
<ul>
<li>Added more consts for preconfigured configs and engines</li>
<li>Make DecodeError::InvalidLastSymbol more clear by including the
decoded value</li>
<li>Added SIMD-accelerated engines behind the default-on
<code>simd-unsafe</code> feature: <code>Simd</code> picks the best
instruction set at runtime (AVX2 on <code>x86_64</code>, NEON on
<code>aarch64</code>) and falls back to the scalar
<code>GeneralPurpose</code> engine, while <code>Avx2</code> and
<code>Neon</code> target one instruction set with no runtime
detection and work in <code>no_std</code>. The engines support the
standard and URL-safe alphabets.</li>
<li>Update MSRV to 1.71.0</li>
<li>Add support for custom padding symbols</li>
</ul>
