It hasn’t even been fully released. But there are many C++14 features that are not supported in VS2015 (see <a href="https://msdn.microsoft.com/en-us/library/hh567368.aspx" class="">https://msdn.microsoft.com/en-us/library/hh567368.aspx</a> and <a href="https://www.visualstudio.com/en-us/news/releasenotes/vs2017-relnotes" class="">https://www.visualstudio.com/en-us/news/releasenotes/vs2017-relnotes</a> ) and we would like to use these features in WebKit.</div><div class=""><br class=""></div><div class="">Would the linux community be able to increase the minimum supported GCC version?</div></body></html>
