.\" $NetBSD: whatis,v 1.14 2000/11/13 01:22:41 hubertf Exp $ . This is the eighth major release of .Nx for the \*M. .Pp As is usual between releases, the \*M port has had many improvements made to it - too many to detail all of them here. .Pp Numerous new drivers have been added. See the supported hardware list for details. .Pp Some (but not all!) notable \*M-specific improvements include: .(bullet Migration to the ELF binary format from a.out. You can still use your pre-1.5 a.out applications, though. .It Preliminary support for MCA (MicroChannel Architecture) .bullet) .Pp .Nx \*V on \*M is, as usual, also fully backward compatible with old .Nx*M binaries, so you don't need to recompile all your local programs provided you set the appropriate binary compatibility options in your kernel configuration.
