While I know I'm tempting fate by sending this out while the patches are
still on autoland, I wanted to start giving people a heads-up now that bug
1424281 has been pushed, which will make Visual Studio 2017 15.6 (Update 6)
the minimum version required to build Gecko 61+ once it merges to m-c.
This change brings a number of improvements over version 15.4, which is
what we've been using in automation since Gecko 58, including performance
wins and better C++17 support. Release notes for versions 15.5 and 15.6 are
linked below with more details:
If you're currently using Visual Studio 2015, you can download the 2017
installer from https://www.visualstudio.com/vs/community/. If you already
have 2017 installed, you should only need to launch the Visual Studio
Installer already on your system and follow the update prompts. Note that
the Windows SDK minimum version was also bumped to version 15063 to match
what we've been using in automation. It is also installable via the Visual
Studio Installer if needed.
