<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>

</li>
<li>
<p>Zhen Zhang got <a href="http://gerrit.cloudera.org:8080/#/c/2858/">a first contribution</a>

possible to query the client to get things like the number of bytes written or
how many write operations were sent.</p>
</li>
