<h3>Changelog</h3>
<ul>
<li>Introduced a warning log message when running <code>guava-android</code> under a Java 7 VM. (Android VMs are unaffected.) This warning is not <em>guaranteed</em> to be logged when running under Java 7, so please don't rely on it as your only warning about future problems. If the warning <em>itself</em> causes you trouble, you can eliminate it by silencing the logger for <code>com.google.common.base.MoreObjects$ToStringHelper</code> (which is used <em>only</em> for this warning). This warning prepares for <a href="https://github-redirect.dependabot.com/google/guava/issues/5269">removing support for Java 7 in 2021</a>. Please report any problems. We have tried to make the warning as safe as possible, but anytime a common library logs, there is the potential for <a href="https://stackoverflow.com/a/41017717/28465"><code>NullPointerException</code></a> or even <a href="https://stackoverflow.com/a/48009613/28465">deadlock</a>. (To be clear, Guava will <em>not</em> log under Java 8 or Android, but it <em>may</em> log under Java 7.) (dc52e6e385)</li>
<li><code>base</code>: Deprecated <code>StandardSystemProperty.JAVA_EXT_DIRS</code>. We do not plan to remove the API, but note that, under recent versions of Java, that property always has a value of <code>null</code>. (38abf07772)</li>
<li><code>net</code>: Added <code>HttpHeaders</code> constants for <code>Origin-Isolation</code> and <code>X-Request-ID</code>. (a48fb4f724, 8319d201cd)</li>
<li><code>reflect</code>: Added <code>ClassInfo.isTopLevel()</code>. (410627262b)</li>
<li><code>util.concurrent</code>: Added <code>ClosingFuture.submitAsync(AsyncClosingCallable)</code>. (c5e2d8d5cb)</li>
