PSA: Visual Studio 2017 15.6 now required to build 61+
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.
