utmapp/UTM v3.2.4 on GitHub

Installation

iOS: Visit https://getutm.app/install/ for the most up to date installation instructions.
macOS: Download "UTM.dmg" below and copy the contents to your /Applications directory.

Highlights

QEMU 7.0.0: The backend has been updated to the latest release. Check out https://www.qemu.org/2022/04/19/qemu-7-0-0/ for more details. Additionally, other backend components such as SPICE GTK, libusbredir, and more have also been updated.
Reclaiming space: the host will attempt to TRIM any page of all zeros when committed to the QCOW2 disk image. Additionally, a new button in disk settings will allow you to re-convert a disk image to reclaim space (of all-zero pages) as well as compress an existing disk image (macOS 12+ only). Note compression is only done statically which means when the guest modifies a sector, it will be stored uncompressed just like before.
Disposable mode: right click/long press on a QEMU VM and select "Run without saving changes" to start VM in "disposable mode." In this mode, changes will not be saved to disk and will be discarded once the VM is stopped. (thanks @ktprograms)

Notes

Reminder: for troubleshooting common Windows install issues (such as no networking), please check out the guide or this guide for Ubuntu install issues.
If you manually added highmem=on or highmem=off to your QEMU Machine Properties as a workaround to issues in a previous release, please remove it.
(iOS) UTM v3.2.x will be the last update to support iOS 11-13. If you are still running those versions, please make sure you report any issues now so they can be fixed by the final release of v3.2.x. After that, iOS 14+ will be required to run future versions of UTM.
