<p><em>Sourced from <a href="https://github.com/google/truth/releases">com.google.truth:truth's releases</a>.</em></p>
<blockquote>
<h2>1.4.1</h2>
<p>This release deprecates <code>Truth8</code>.</p>
<p>All its methods have become available on the main <code>Truth</code> class. In most cases, you can migrate your whole project mechanically: <code>git grep -l Truth8 | xargs perl -pi -e 's/\bTruth8\b/Truth/g;'</code></p>
<p>While we do not plan to delete <code>Truth8</code>, we recommend migrating off it, at least if you static import <code>assertThat</code>: If you do not migrate, such static imports will become ambiguous in Truth 1.4.2, breaking your build.</p>
