main purpose is help you ensure that your programs will be runnable when you
switch from PyTables 1.0 to PyTables 1.1.</p>

<ul class="simple">
<li><tt class="docutils literal"><span class="pre">Table.read()</span></tt> raises a <tt class="docutils literal"><span class="pre">KeyError</span></tt> instead of a <tt class="docutils literal"><span class="pre">ValueError</span></tt> when a
nonexistent field name is specified, for consistency with other methods.
The same goes for the <tt class="docutils literal"><span class="pre">col()</span></tt> method.</li>
<li><tt class="docutils literal"><span class="pre">File.__contains__()</span></tt> returns a true value when it is asked for an existent
node, be it visible or not. This is more consistent with
<tt class="docutils literal"><span class="pre">Group.__contains__()</span></tt>.</li>

<ul class="simple">
<li>Using <tt class="docutils literal"><span class="pre">table.cols['colname']</span></tt> is deprecated. The usage of
<tt class="docutils literal"><span class="pre">table.cols._f_col('colname')</span></tt> (with the new <tt class="docutils literal"><span class="pre">Cols._f_col()</span></tt> method) is
