86Box v4.2 is released. 86Box is a low level x86 emulator that runs older operating systems and software designed for IBM PC systems and compatibles from 1981 through fairly recent system designs based on the PCI bus.

86Box Features:
Easy to use interface inspired by mainstream hypervisor software
Low level emulation of 8086-based processors up to the Pentium with focus on accuracy
Great range of customizability of virtual machines
Many available systems, such as the very first IBM PC 5150 from 1981, or the more obscure IBM PS/2 line of systems based on the Micro Channel Architecture
Lots of supported peripherals including video adapters, sound cards, network adapters, hard disk controllers, and SCSI adapters
MIDI output to Windows built-in MIDI support, FluidSynth, or emulated Roland synthesizers
Supports running MS-DOS, older Windows versions, OS/2, many Linux distributions, or vintage systems such as BeOS or NEXTSTEP, and applications for these systems
