1076<p>Clang generally aims to implement resolutions to Defect Reports (bug fixes
1077against prior standards) retroactively, in all prior standard versions where
1078the fix is meaningful. Significant Defect Report changes to language features
1079after the publication of the relevant standard are marked (DR) in the above
1080table.</p>
1081
1082<p>Clang also has a test suite for conformance to resolutions for issues on the
1083<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_toc.html">C++ core issues list</a>,
1084most of which are considered Defect Reports.
