<blockquote>
<h1>Release 0.2.12 (2020-06-11)</h1>
<ul>
<li><a href="https://github-redirect.dependabot.com/rust-num/num-traits/pull/153">The new <code>WrappingNeg</code> trait</a> will wrap the result if it exceeds the
boundary of the type, e.g. <code>i32::MIN.wrapping_neg() == i32::MIN</code>.</li>
<li><a href="https://github-redirect.dependabot.com/rust-num/num-traits/pull/165">The new <code>SaturatingAdd</code>, <code>SaturatingSub</code>, and <code>SaturatingMul</code> traits</a>
will saturate at the numeric bounds if the operation would overflow. These
soft-deprecate the existing <code>Saturating</code> trait that only has addition and
subtraction methods.</li>
<li><a href="https://github-redirect.dependabot.com/rust-num/num-traits/pull/171">Added new constants for logarithms, <code>FloatConst::{LOG10_2, LOG2_10}</code></a>.</li>
</ul>
