<h3>Change Log :</h3>
<li><font size="2"><strong>Release Notes</strong></font><ol>
<li><font size="2"><em><strong>Version 1.1 to 2.0; Released March 10th 2001.</strong></em></font>
<ol>
<li><font size="2">Added support for Boris Fomitchev's
STLPort implementation of the SGI Standard
Template Library.</font></li>
<li><font size="2">Successfully ported code
to Red Hat Linux 7 under gcc 2.95 running
unixODBC and a MySQL 3.23.33 database.</font></li>
<li><font size="2">Corrected constness
throughout DTL. This fixed some issues that we had in 1.1 which
prevented us from running correctly versus some of the standard
STL algorithms.</font></li>
<li><font size="2">Rewrote the code to make
it exception safe.</font></li>
<li><font size="2">Added error handling
support for all DTL iterator classes,
DBView, and IndexedDBView in the form of
IOHandler.</font></li>
<li><font size="2">Iterator refinements: </font><ol>
<li><font size="2" face="Courier New">DB_select_iterator::operator*()
</font><font size="2">now returns

emulate </font><font size="2"
face="Courier New">*it = value to
</font><font size="2">enforce
their write-only quality.</font> </li>
<li><font size="2">Also fixed prefix/postix
implementation for </font><font

</font><font size="2">on all
iterators. </font></li>
</ol>

<li><font size="2">Enhanced </font><font
size="2" face="Courier New">DBConnection </font><font
size="2">class to use ODBC connection
pooling. </font></li>

the </font><font size="2"
face="Courier New">jtime_c </font><font
size="2">class. <br>
</font></li>
<li><font size="2">Simplified the structure for </font><font size="2"
face="Courier New">DBView </font><font
size="2"> to need fewer template parameters. In version 1.1
the structure was </font><font size="2"
face="Courier New">DBView<DataObj, ParamObj, BCA, BPA> </font><font
size="2"> in version 2.0 the structure is simplified to </font><font size="2"
