Since we are targeting C++14 compilers, GCC 4.9 and Visual Studio 2015 will become unsupported 1 month after the release of Debian 9.
We give this warning to allow people to ready their systems with enough time to update (it’s very likely Debian 9 will be shipped on 2nd quarter 2017).
(Visual Studio 2017 release date is March 7)
Debian 9 released we recommend to update before 1 month or you very likely will have compile broken if you still use gcc to compile.
Since 232db97 the minimum required boost version is increased to 1.56 making Debian 8 apt-get installed boost unsupported, you need to hand compile boost on Debian 8 or upgrade your Debian installation to 9.
In order to support C++14 properly the required compiler versions of both branches since b9b667f92 are:
[ul]
[li]Visual Studio 2017[/li]
[li]GCC 6.3 (current stable version of Debian 9)[/li]
[li]Clang 3.9 (current stable version of Debian 9 - might work with earlier versions)[/li]
[/ul]
