I'm planning to move production Windows builds to VS2017 (15.4.1) in bug 1408789.
VS2017 has optimizer improvements that produce faster code. I've seen 3-6% improvement on Speedometer. There is also increased support for C++14 and C++17 language features: https://docs.microsoft.com/en-us/cpp/visual-cpp-language-conformance These days we tend not to support older VS for too long, so after some transition period you can probably expect that VS2017 will be required to build locally, ifdefs can be removed, etc. VS2017 Community Edition is a free download and it can coexist with previous compilers. Installation instructions are at: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Windows_Prerequisites#Visual_Studio_2017 If you have concerns, please talk to me or visit the bug. Thanks! _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
