 * **Extreme memory footprint**: A minimal bootable 64-bit web server, including operating system components and a anything needed from the C/C++ standard libraries is currently 2.5 MB.
 * **KVM, VirtualBox and VMWare support** with full virtualization, using [x86 hardware virtualization](https://en.wikipedia.org/wiki/X86_virtualization), available on most modern x86 CPUs. IncludeOS will run on any x86 hardware platform, even on a physical x86 computer, given appropriate drivers. Officially, we develop for- and test on [Linux KVM](http://www.linux-kvm.org/page/Main_Page), and VMWare [ESXi](https://www.vmware.com/products/esxi-and-esx.html)/[Fusion](https://www.vmware.com/products/fusion.html) which means that you can run your IncludeOS service on Linux, Microsoft Windows and macOS, as well as on cloud providers such as [Google Compute Engine](http://www.includeos.org/blog/2017/includeos-on-google-compute-engine.html), [OpenStack](https://www.openstack.org/) and VMWare [vcloud](https://www.vmware.com/products/vcloud-suite.html).
 * **Instant boot:** IncludeOS on Qemu/kvm boots in about 300ms but IBM Research has also integrated IncludeOS with [Solo5/uKVM](https://github.com/Solo5/solo5), providing boot times as low as 10 milliseconds.
-* **C++11/14 support**
+* **Modern C++ support**
     * Full C++11/14/17 language support with [clang](http://clang.llvm.org) 5 and later.
     * Standard C++ library (STL) [libc++](http://libcxx.llvm.org) from [LLVM](http://llvm.org/).
     * Exceptions and stack unwinding (currently using [libgcc](https://gcc.gnu.org/onlinedocs/gccint/Libgcc.html)).
