<h3 id="table-namespaces">Table namespaces</h3>
<p>Administering an Accumulo instance with many tables is cumbersome. To ease this, <a href="https://issues.apache.org/jira/browse/ACCUMULO-802" title="Table namespaces">ACCUMULO-802</a> introduced table namespaces which allow tables to be grouped into logical collections. This allows configuration and permission changes to made to a namespace, which will apply to all of its tables. Example use cases are ... TODO</p>
<h3 id="conditional-mutations">Conditional Mutations</h3>
-<p>Accumulo now offers a way to make atomic read,modify,write row changes from the client side. Accumulo now supports atomic test and set row operations. <a href="https://issues.apache.org/jira/browse/ACCUMULO-1000" title="Conditional Mutations">ACCUMULO-1000</a> added conditional mutations and a conditional writer. A conditional mutation has tests on columns that must pass before any changes are made. These test are executed in server processes while a row lock is held. Below is a simple example of making atomic row changes using conditional mutations.</p>

<li>Read columns X,Y,SEQ into a,b,s from row R1 using an isolated scanner.</li>
<li>For row R1 write conditional mutation X=f(a),Y=g(b),SEQ=s+1 if SEQ==s.</li>
