<p>This document details the modifications to PyTables since version 1.3. Its
main purpose is help you ensure that your programs will be runnable when you
switch from PyTables 1.3 to PyTables 1.4.</p>
<div class="section" id="api-additions">
<h2>API additions<a class="headerlink" href="#api-additions" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li>The <tt class="docutils literal"><span class="pre">Table.getWhereList()</span></tt> method has got a new <tt class="docutils literal"><span class="pre">sort</span></tt> parameter. The
default now is to get the list of parameters unsorted. Set <tt class="docutils literal"><span class="pre">sort</span></tt> to True
to get the old behaviour. We’ve done this to avoid unnecessary ordering of
potentially large sets of coordinates.</li>
<li>Node creation, copying and moving operations have received a new optional
<cite>createparents</cite> argument. When true, the necessary groups in the target
path that don’t exist at the time of running the operation are automatically
created, so that the target group of the operation always exists.</li>
</ul>

<div class="section" id="api-refinements">
<h2>API refinements<a class="headerlink" href="#api-refinements" title="Permalink to this headline">¶</a></h2>
<ul class="simple">
<li><tt class="docutils literal"><span class="pre">Description._v_walk()</span></tt> has been renamed to <tt class="docutils literal"><span class="pre">_f_walk()</span></tt>, since it is a
public method, not a value.</li>
<li><tt class="docutils literal"><span class="pre">Table.removeIndex()</span></tt> now accepts a column name in addition to an
<tt class="docutils literal"><span class="pre">Index</span></tt> instance (the later is deprecated). This avoids the user having
to retrieve the needed <tt class="docutils literal"><span class="pre">Index</span></tt> object.</li>
