    "As indicated above, we tried to specify clearly in which standard specific features were introduced. Few guidelines:\n",
    "\n",
-    "- C++ 14 is now a safe bet for most compilers, so you should probably choose this one instead of C++ 11. Vincent is working on a library named [Gudhi](https://gudhi.inria.fr/) that is rather conservative for the standard use (in the sense they want most users to be able to compile the code without having to install brand new environment) and they switched to C++ 14 in August 2019.\n",
-    "- C++ 17 support is now really widespread as well, but you may still lack some features if your distro is a bit backward (for instance default gcc compiler on still supported Ubuntu LTS 18.04 does not support the brand new filesystem library (yes C++ was not historically a _batteries included_ language...)). \n",
