 <h2 id="development-discussions-and-code-in-progress">Development discussions and code in progress</h2>

 <ul>
   <li>
     <p>Sameer Abhyankar posted a <a href="http://gerrit.cloudera.org:8080/#/c/2986/">patch</a>
 for <a href="https://issues.apache.org/jira/browse/KUDU-1363">KUDU-1363</a>
 that adds the ability to specify
 <a href="http://www.w3schools.com/sql/sql_in.asp">IN</a>-like predicates on column values.</p>
   </li>
   <li>
     <p>Chris George and Andy Grove have both been adding new features in Kudu’s
 Spark module such as methods to <a href="http://gerrit.cloudera.org:8080/#/c/2981/">create/delete tables</a>
 and <a href="http://gerrit.cloudera.org:8080/#/c/2992/">insert/update rows in the DataSource</a>.</p>
   </li>
   <li>
     <p>Todd Lipcon <a href="https://issues.apache.org/jira/browse/KUDU-1437">fixed a bug</a> in RLE
 encoding that was reported by Przemyslaw Maciolek. Thank you Przemyslaw for
 reporting it and providing an easy way to reproduce it!</p>
   </li>
   <li>
     <p>Adar Dembo is currently working on addressing the
 <a href="https://github.com/cloudera/kudu/blob/master/docs/design-docs/multi-master-1.0.md">issues with multi-master</a>
 and early last week he got <a href="http://gerrit.cloudera.org:8080/2879">a</a>
 <a href="http://gerrit.cloudera.org:8080/2928">few</a> <a href="http://gerrit.cloudera.org:8080/2891">patches</a>
 in that address some race conditions.</p>
   </li>
   <li>
     <p>Zhen Zhang got <a href="http://gerrit.cloudera.org:8080/#/c/2858/">a first contribution</a>
 in with a patch that adds statistics in the Java client. In 0.9.0 it will be
 possible to query the client to get things like the number of bytes written or
 how many write operations were sent.</p>
   </li>
 </ul>

 <h2 id="upcoming-talks-and-meetups">Upcoming talks and meetups</h2>

 <ul>
   <li>Dan Burkert and Mike Percy will present Kudu at the
