v4.3.1 (Beta)

[osy]

Highlights

• QEMU backend updated to v8.0.2
• Rewrite of QEMU support internals. Much of the code to support QEMU has been refactored into a new project, QEMUKit, which will make it easier to support QEMU changes as well as support for new platforms. This means that v4.3.1 may contain a lot of UI bugs as testing is needed to make sure the new internals match up with the existing UI. Please help us by reporting any such issue you stumble upon.

Changes (v4.3.1)

• Updated QEMU backend to v8.0.2
• Refactored QEMU support to a new project: QEMUKit
• Machines with IDE interface (i44FX/PIIX) will now support two units per bus. Previously, we mapped IDE devices to one unit per bus. This means on some machines, the limit was two devices maximum. Now, we map two units per IDE bus which should increase the limit to four devices. Existing VMs will not get this change automatically in order to maintain compatibility. You can choose to opt-in to this new mapping by pressing the “Update Interface” button on each IDE drive in the VM settings. (Error when using more than two IDE devices on ISAPC - bootindex=2: Bus 'ide.2' not found #5358)
• Localization: Updated Japanese (thanks @MMP0 and @studio1a9)
• (macOS) Fixed crash when AVM window is closed (UTM crashes when last VM window is closed #5347)
• (macOS) New option “Automatic” for bridged network connection which will use the bridge the first active connection on the host. Both AVM and QEMU backends are supported. (Auto detect network interface for "Bridged" networking #5410)
• (macOS) Fixed trackpad setting not saving (macOS Guest: When Use Trackpad is enabled from UTM.app GUI, it is not saved in config.plist #5369)

Changes (v4.3.0)

• Updated QEMU backend to v8.0.0
• Changed audio backend from CoreAudio back to SPICE (as it was before v4.2.x). Clarify that CoreAudio backend does not support microphone (Microphone not working in CoreAudio backend #5253)
• Add support for mouse buttons 4 and 5 (Mouse Button 4 and 5 pass through to Windows 11 ARM Guest on Apple Silicon. #5295)
• Wizard: Properly display an error message when there is a failure writing to disk (No verification when VM creation fails #5271)
• Fixed an issue where ISAPC emulation target cannot be started (unable to start isapc emulated - No 'PCI' bus found for device 'virtio-serial-pci' #5280)
• Fixed CoreAudio being instantiated even when audio is disabled
• Fixed an issue where legacy VMs with AC97 sound card has an empty name in settings
• Fixed an QEMU issue where the ucomiss instruction causes a crash in some applications (Crash when executing ucomiss instructions emulating an x86-64 CPU on an AArch64 host #5294)
• Fixed an issue preventing VMs with commas in their name from starting (note only new VMs will be fixed) (VM does not start, when having a comma in name #5332)
• (macOS) AVM: Support canceling macOS installation
• (macOS) utmctl: Added delete command (Delete VM through utmctl #5290)
• (macOS) Fixed an issue creating a shortcut from drag & drop as well as double clicking from Finder (Drag and drop a UTM file results in error, opening it does work #5310, Adding a VM as link requires to readd it after closing UTM #5311)
• (macOS) Added DHCP start/end settings for vmnet (Separate DHCP end address and subnet mask (vmnet) #5301)
• (macOS) Added automatically syncing of system clock when macOS wakes up from sleep (when QEMU guest agent is installed) (Update clock when host wakes up from sleep #5252)

Installation

• iOS
• macOS

File	Description	Installation	JIT	Hypervisor	USB
UTM.deb	Jailbroken iOS version	Open in Cydia, dpkg, or Sileo	Yes	Yes(1)	Yes
UTM.dmg	macOS version	Mounting and copying UTM.app to /Applications	Yes	Yes	Yes
UTM.ipa	Non-jailbroken iOS version (sideloading)	AltStore, etc (see guide)	Yes(2)	No	No
UTM.HV.ipa	Non-jailbroken iOS version (TrollStore)	TrollStore	Yes	Yes(1)	Yes
UTM.SE.ipa	Non-jailbroken iOS version (sideloading)	AltStore, enterprise signing, etc	No	No	No

1. Hypervisor on iOS requires an M1 iPad.
2. Enabling JIT may require a separate JIT enabler such as Jitterbug or Jitstreamer.
