DOSBox-X (2018/02/02) is released. DOSBox-x is a branch of DOSBox v0.74. DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD.

DOSBox-X Changelog:
ALT+TAB fixes, focus additions.
3Dfx emulation fixed never to run fullscreen. It will leave fullscreen if necessary.
Added code to enforce no resizing or scaling of the 3Dfx overlay
