<blockquote>
<h2>[0.2.1] - 2019-12-29</h2>
<h3>Fixed</h3>
<ul>
<li><code>mul_div_round()</code> rounds down now for <code>-x.5</code> instead of rounding up, as
documented and as the <code>round()</code> function in <code>std</code> does</li>
</ul>
<h3>Changed</h3>
<ul>
<li>All tests were ported to <code>quickcheck</code></li>
<li>The crate is <code>no_std</code> by default now as we don't need any <code>std</code> API outside
the tests</li>
<li>Documentation was improved and examples converted to proper doctests</li>
</ul>
