https://svn.boost.org/trac10/ticket/10332 <p> The »indexed« range adaptor has changed in v1.56.0 in source-breaking ways. I get the change and that it was necessary for range-based for loops, but this means that you now have to <code>#if BOOST_VERSION &lt; …</code> around it. See <a class="ext-link" href="http://boost.codepad.org/VE1QSmSz"><span class="icon">​</span>this example</a> (distilled from actual code). </p> <p> Why the ticket? Because the change hasn't been mentioned at all in the <a href="http://www.boost.org/users/history/version_1_56_0.html">release notes</a>. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/10332 Trac 1.4.3 anonymous Mon, 01 Sep 2014 11:38:48 GMT https://svn.boost.org/trac10/ticket/10332#comment:1 https://svn.boost.org/trac10/ticket/10332#comment:1 <ul> <li><strong>owner</strong> changed from <span class="trac-author">Matias Capeletto</span> to <span class="trac-author">Neil Groves</span> </li> <li><strong>component</strong> <span class="trac-field-old">Documentation</span> → <span class="trac-field-new">range</span> </li> </ul> Ticket Neil Groves Mon, 01 Sep 2014 11:54:45 GMT https://svn.boost.org/trac10/ticket/10332#comment:2 https://svn.boost.org/trac10/ticket/10332#comment:2 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">assigned</span> </li> </ul> Ticket
