<p><em>Sourced from <a href="https://github.com/google/truth/releases">com.google.truth:truth's releases</a>.</em></p>
<blockquote>
<h2>1.1.5</h2>
<ul>
<li>Updated Truth to depend on <a href="https://github.com/google/guava/releases/tag/v32.0.1">Guava 32.0.1</a>. The previous Guava version, 32.0.0, contained a bug under Windows, which did not affect Truth's functionality but <a href="https://redirect.github.com/google/truth/issues/1137">could cause problems</a> for people who use Guava's I/O functionality in their codebase. Affected users can already manually update their Guava dependency to 32.0.1, but if they don't depend directly on Guava, they may find it easier to upgrade to this new Truth release instead.</li>
<li>Fixed <code>IterableOfProtosSubject</code> to produce a proper failure message instead of NPE when the actual value is <code>null</code>.</li>
</ul>
<h2>1.1.4</h2>
<ul>
<li>Updated Truth to build with <code>-source 8 -target 8</code>. This means that it no longer runs under Java 7 VMs. It continues to run under Android, even old versions, for all apps that have <a href="https://developer.android.com/studio/write/java8-support#supported_features">enabled support for Java 8 language features</a>. (db5db2429)</li>
<li>Updated Truth to depend on Guava 32.0.0. That release contains changes related to CVEs. Neither of the CVEs relates to any methods that are used by Truth, so this version bump is just about eliminating any warnings related to the old version and helping tools like Maven to select the newest version of Guava. (f8d4dbba8adc65effba70879d59a39da092dce51, 99b1df8852a25b5638590bea1b55a31ae536936d)</li>
<li>Added support for <code>value of: method()</code> to <code>expect.that</code>, matching the existing support for <code>assertThat</code>. (bd8efd003)</li>
<li>Enhanced <code>IterableSubject.containsAtLeastElementsIn().inOrder()</code> to print an extra line that shows only the expected elements in their actual order. (9da7dd184)</li>
<li>Annotated Truth for nullness. (2151add71)</li>
</ul>
