DOSBox is a free and open-source, high-level 286 and 386 emulator written in C++.
Hey DOS enthusiasts! We are proud to present DOSBox Staging 0.81.0 to you, a rather substantial release containing a large number of exciting new features and improvements!
For the first time in history, DOSBox comes with built-in authentic CRT monitor emulation that just works out-of-the-box without any manual configuration required. The VGA code has been overhauled, shortcuts and simplifications have been removed, and now we’re defaulting to accurate per-scanline emulation and double scanning in all VGA, SVGA, and VESA modes. Integer scaling options have been added, it’s now possible to stretch the image to fullscreen, force any arbitrary aspect ratio, or even emulate the horizontal and vertical stretch controls of CRT monitors in real-time. Screenshots have been made aspect ratio correct by default, and image capturing has become multi-threaded, so it no longer causes audio hiccups and micro-pauses. Video capturing has been made about three times more performant. Oh, almost forgot: we’ve also added 3dfx Voodoo 1 support for the fans of those late 90s 3D DOS games! 😎 🤘
Well, that’s just the video side of things. We’ve added support for the ultra-rare IBM Music Feature Card, dealing with Roland MT-32 ROMs has become much easier, plus we’ve made numerous MIDI-related improvements as well. Not to mention all the mouse and joystick enhancements and fixes, the addition of a few missing DOS commands, improved filesystem integration, fixing some long-standing annoying shortcomings of the FPU emulation in non-x86 builds, taking localisation support to the next level, and the list just goes on and on

QEMU is a generic and open source machine emulator and virtualizer.
Removed features and incompatible changes
Consult the 'Removed features' page for details of suggested replacement functionality.
The HAX accelerator is not supported anymore; the project has been retired. Use "whpx" or "hvf" respectively on Windows and macOS.
The old machine types pc-i440fx-1.4 to pc-i440fx-1.7 have been removed; use a newer machine type instead
In addition to -audiodev and -audio, QEMU does not create default audio backends anymore if the -nodefaults option are used on the command line.
If an audio backend is created with -audiodev, each audio client (a sound card or VNC) that wants to use it has to specify an audiodev= property. Previously, the first audiodev command line option would be used as a fallback. However -audio can now be used to configure one or more default audio backends, in lieu of the (deprecated and now removed) QEMU_AUDIO_* environment variables.
Running QEMU with KVM requires Linux 4.4 or newer. A future version of QEMU will increase the minimum requirement for Arm hosts to Linux 4.19 (also when running KVM); if this is too restrictive for your use case, please contact us at [email protected].
New deprecated options and features
Consult the "Deprecated Features" chapter of the QEMU System Emulation User's Guide for further details of the deprecations and their suggested replacements.

Xtensa
Device emulation and assignment
ACPI / SMBIOS
Audio
Added virtio-sound device which implements capture and playback from inside a guest using the configured audio backend of the host machine. It is documented in the "Device Emulation / virtio sound" page.
Block devices
Parallels Format Driver
Improved 'qemu-img check' facility
Recover from broken data_off in the header
Drop clusters outside of the image file
De-duplicate clusters located on the same offset in the host file

ati-vga pixman-less support and fixes
virtio-gpu blob=true VM can now be migrated
Hyper-V
New Hyper-V Dynamic Memory protocol device hv-balloon. This driver is like virtio-balloon on steroids for Windows guests: it allows both changing the guest memory allocation via ballooning and inserting pieces of extra RAM into it on demand from a provided memory backend via Windows-native Dynamic Memory protocol.
I2C
Input devices
IPMI
Multi-process QEMU
Network devices
NVDIMM
NVMe
PCI/PCIe
Added Astro Memory controller with Elroy PCI host busses for PA-RISC (hppa) machines

Support for multiple logical units through the ufs-lu device
Support for UFS initialisation
Support for SCSI commands including read/write.
Support for query request commands
Typical usage:
-drive file=<file>,if=none,id=<drive_id>
-device ufs,serial=<serial>,id=<bus_name>, nutrs=<N[optional]>,nutmrs=<N[optional]>
-device ufs-lu,drive=<drive_id>,bus=<bus_name>
USB
VFIO
P2P support for VFIO migration
Removal of NVIDIA V100 GPU with NVLink2 support (PPC)
Dynamic MSI-X allocation support
ramfb migration support
Support for non 64b IOVA space
Preparatory changes for new IOMMUFD backend
virtio
virtio-mem now supports to dynamically consume multiple memslots instead of statically a single big one. The feature can be enabled using "dynamic-memslots=on", which can severely reduce KVM memory slot metadata overhead with large virtio-mem devices that only expose a small amount of memory to the VM. Note that the feature is incompatible with vhost devices that provide less than 509 memslots, like most vhost-user devices.
Added virtio-sound device. See Audio section/virtio-sound
vDPA
Xen
Support PV unplug for AHCI disks with the q35 platform.
Allow creation of PV console devices from the command line.
Allow creation of PV network devices, including '-nic xxx,model=xen-net-device' and the default NIC.
Support '-drive file=FILENAME,if=xen' for creating PV block devices with automatic names.

windows support
Host support
Memory backends
memory-backend-file now supports the "rom" parameter. "share=off,readonly=off,rom=on" can be used for VM-templating with R/O files: open the file R/O, but create writable RAM instead of Read Only Memory (ROM).
"VM templating" documentation was added
Migration
Legacy compression migration is deprecated ("compress" as capability, "compress-level", "compress-threads", "compress-wait-thread", "decompress-threads" as parameters). Suggest to use multifd compression instead.
Block migration is deprecated. QMP command "migrate" parameters "blk" and "inc" are deprecated. Suggest to use driver-mirror with NBD instead.
Fixed race conditions for postcopy migration when preempt mode is enabled.
Postcopy recovery now allows network failure to happen even during RECOVER phase.
Added migration parameter "avail-switchover-bandwidth" migration parameter, can be used when the user observes extremely slow bandwidth during migration, causing migration to never complete.
Initial part of migration mode "cpr-reboot" integrated.
Monitor
QMP
HMP
Network
Block device backends and tools
The qemu NBD implementation for both server and client now supports the recent NBD protocol extension of 64-bit extended headers. When both sides of an NBD connection support this extension, commands like write zeroes or block status can operate on 64-bit effect lengths, rather than being capped to transaction sizes smaller than 4G.

Build Information
Coding style has been updated to allow loop variables
It is possible to build a non-relocatable binary of QEMU with the configure option --disable-relocatable. The default remains a relocatable install (that is, all the directories within the install prefix are computed based on the path to the executable).
Build Dependencies
Building QEMU now requires Python 3.8. As a consequence, building on Debian 10 is not supported anymore (unless a newer version of Python is installed by other means).
Building QEMU now uses the tomli library if Python is older than version 3.11. However, version 2.0.1 is bundled in case tomli is not installed on the host.
The libfdt library is no longer bundled with QEMU. However, if QEMU is configured with --enable-download and the library is absent, then it will be downloaded and built together if any emulators need it.
The Pixman library is no longer strictly required. The VC, VNC, Gtk, Spice, screendump features and a few devices still require it.
When running make check-avocado, the Avocado testing framework and pycdlib must be present if the build tree was configured with --disable-download. Until 8.1, Avocado was always downloaded from PyPI.
Docker Tweaks
debian-i686 replaces fedora-i386 for 32 bit x86 cross builds
debian-am64 and debian-native merged into a common debian container built from lcitool for latest deps
Windows
Testing and CI
ccache has been enabled for CI builds
