<h3>Changelog</h3>
<ul>
<li><a href="https://groups.google.com/d/msg/guava-announce/zHZTFg7YF3o/rQNnwdHeEwAJ">Guava types can no longer be sent over GWT-RPC.</a> To <em>temporarily</em> reenable support, set the <code>guava.gwt.emergency_reenable_rpc</code> system property to <code>true</code>. (5214a10b1e)
<ul>
<li>This is the only breaking change in this release, and it affects only users of the <code>guava-gwt</code> artifact, not people who use only the <code>guava</code> artifact. This release contains no changes that break <em>binary compatibility</em> for any users.</li>
</ul>
</li>
<li>API documentation for Guava classes is now easier to reach. For example, for <code>ImmutableList</code>, visit <a href="https://guava.dev/ImmutableList">guava.dev/ImmutableList</a>. Also, more easily access the index at <a href="https://guava.dev/api">guava.dev/api</a>.</li>
<li><code>collect</code>: Annotated <code>FluentIterable.from(FluentIterable)</code> with <code>@DoNotCall</code>. (b1c77b7df3)</li>
<li><code>collect</code>: Made <code>ceiling</code>, <code>floor</code>, <code>headSet(E, boolean)</code>, and <code>tailSet(E, boolean)</code> methods available in the GWT-emulated <code>ImmutableSortedSet</code>. (7e0fe90ca8, 5f2fbf27b2)</li>
<li><code>graph</code>: Made it possible to set a stable incident edge order by calling the newly added method <code>[Value]Graph.Builder.incidentEdgeOrder(ElementOrder.stable())</code>. (70164025a8)</li>
<li><code>graph</code>: Added <code>incidentEdgeOrder()</code> to the <code>[Value]Graph</code> interfaces. (cde576ec00)</li>
<li><code>util.concurrent</code>: Added <code>Duration</code>-based <code>default</code> methods to <code>ListeningScheduledExecutorService</code>. (931e83f969)</li>
<li><code>util.concurrent</code>: Added <code>immediateVoidFuture</code>. (9f3bae5853)</li>
<li><code>util.concurrent</code>: Removed <code>@Beta</code> from <code>Service</code> and related classes. (dc46627fea)</li>
<li><code>util.concurrent</code>: Deprecated the 1-arg overload of <code>ServiceManager.addListener</code>. (86e3620125)</li>
<li><code>util.concurrent</code>: Changed the return type of <code>ServiceManager.servicesByState()</code> to <code>ImmutableSetMultimap</code> (but also retained a method with the old signature for binary compatibility). (31999ae6f5)</li>
<li><code>util.concurrent</code>: Made it safe to load the <code>AbstractFuture</code> class from a <code>ForkJoinPool</code> thread under a security manager. (6e0c5b5d50)</li>
</ul>
<h2>28.2</h2>
<h3>Maven</h3>
<pre lang="xml"><code>&lt;dependency&gt;
  &lt;groupId&gt;com.google.guava&lt;/groupId&gt;
  &lt;artifactId&gt;guava&lt;/artifactId&gt;
  &lt;version&gt;28.2-jre&lt;/version&gt;
  &lt;!-- or, for Android: --&gt;
  &lt;version&gt;28.2-android&lt;/version&gt;
