<h1>Changes: 3.17<a class="headerlink" href="#changes-3-17" title="Link to this heading">#</a></h1>
<p class="rubric">General:</p>
<ul class="simple">
<li><p>PETSc now requires a C99 compliant C compiler in all cases. Previously C99 was only required when building PETSc, but this now extends to public interfaces and header-files</p></li>
<li><p>PETSc now requires a C++11 compliant C++ compiler. Note this requirement is only enforced if C++ is used; it is acceptable to have a compiler that does not support C++11 if you only ever build C source</p></li>
<li><p>PETSc now requires at least Microsoft Visual Studio 2015 when using the Microsoft Visual C/C++ Compiler</p></li>
<li><p>Change <code class="docutils notranslate"><span class="pre"><a href="../manualpages/Sys/MPIU_Allreduce.html">MPIU_Allreduce</a>()</span></code> to always returns a PETSc error code that should be checked with <code class="docutils notranslate"><span class="pre"><a href="../manualpages/Sys/CHKERRQ.html">CHKERRQ</a>(ierr)</span></code> or <code class="docutils notranslate"><span class="pre"><a href="../manualpages/Sys/PetscCall.html">PetscCall</a>()</span></code></p></li>
</ul>
<p class="rubric">Configure/Build:</p>
<ul class="simple">
<li><p>Change minimum value of <code class="docutils notranslate"><span class="pre">--with-cxx-dialect</span></code> argument from “03” to “11”</p></li>
<li><p>C++ dialect will now also be inferred from compiler flags, although users will be warned that they should let PETSc auto-detect the flag when setting the dialect this way</p></li>
<li><p>Change C++ dialect flag option to be consistent with compiler flags; <code class="docutils notranslate"><span class="pre">--with-cxx-dialect=gnu++14</span></code> means you want <code class="docutils notranslate"><span class="pre">-std=gnu++14</span></code>, no more, no less</p></li>
<li><p>Fix for requesting no C++ dialect flag via <code class="docutils notranslate"><span class="pre">--with-cxx-dialect=0</span></code>. Previously <code class="docutils notranslate"><span class="pre">configure</span></code> would bail out immediately without running the tests and therefore wouldn’t set any of the capability defines. <code class="docutils notranslate"><span class="pre">configure</span></code> now runs all tests, just doesn’t add the flag in the end</p></li>
<li><p>Fix a number of corner-cases when handling C++ dialect detection</p></li>
<li><p>Remove deprecated <code class="docutils notranslate"><span class="pre">PETSC_VERSION_PATCH</span></code> so as to not have confusion with patch releases where the subminor version changes</p></li>
<li><p>Change <code class="docutils notranslate"><span class="pre">PETSC_HAVE_MKL</span></code> to <code class="docutils notranslate"><span class="pre">PETSC_HAVE_MKL_LIBS</span></code></p></li>
<li><p>Add <code class="docutils notranslate"><span class="pre">PETSC_HAVE_MKL_INCLUDES</span></code></p></li>
<li><p>Enable HYPRE GPU for 64bit indices build (using HYPRE’s mixed-int configuration)</p></li>
<li><p>Reuse PETSc-installed hwloc when installing Open MPI</p></li>
</ul>
