<p>It gives me great pleasure to announce the release of version 3.600 of K-9 Mail. &#160;Notable in this release are significant performance improvements and proper support for replying to / forwarding HTML mail.</p>
<p>While K-9 was originally &quot;my fault&quot;, its continued success wouldn&#039;t be possible without the hard work of a number of contributors and committers. &#160;At the risk of accidentally leaving out any recent contributor, I&#039;d particularly like to thank (in alphabetical order):&#160;</p>
<p>&#160;&#160;&#160;&#160;achen.code, cketti, fiouzy,&#160;hiranotaka,&#160;jca02266,&#160;kris.p.wong, and marcus.wolschon</p>
<p>Their bug triage and commits are a big part of why K-9 is as wonderful as it is.</p>
<p>A rough changelog of &quot;important&quot; updates in K-9 3.6 follows:</p>
<h2>Settings</h2>
<ul>
<li>Restore &quot;only vibrate once&quot; vibration notification option.</li>
