Windows virtual machines restart and shut down more reliably. Stability improvements.

• Ubuntu, Debian and Fedora virtual machines can now be created ready to use, without going through an installer: your account is set up on first boot, and a GNOME desktop can be added. • Windows virtual machines install without any further steps once you choose an ISO, Kyvenza's drivers and tools included. • When a Linux installer finishes, Kyvenza detaches the installer image on its own. • The new virtual machine window and virtual machine settings show the common options first, with the rest under More Options and Advanced. • Linux cloud image downloads pick up where they left off after a dropped connection. • Linux virtual machines are more reliable under heavy disk activity. • Stability improvements.

• Disposable sandboxes: clone a virtual machine into a throwaway copy, with or without network access, that moves to the Trash when it expires. • Kyvenza can stay in the menu bar and open at login, and chosen virtual machines can start along with it. • macOS virtual machines can now be suspended and resume exactly where you left off. • Kyvenza is now available in Traditional Chinese, Japanese, Korean, French and German. • Windows virtual machines: ⌘ works as Ctrl, the toolbar has a Ctrl+Alt+Delete button, and the display reconnects on its own after a disconnect. • Stability improvements.

• USB passthrough: on a Mac running macOS 27 or later, connect USB devices to macOS and Linux virtual machines from the USB button in the VM window. • Backups now show progress and can be cancelled, and restored virtual machines take up only the disk space they actually use. • Stability improvements.

• Graphics acceleration for Windows (experimental): Windows virtual machines can use your Mac’s GPU for DirectX 11. Run Install-Kyvenza-Drivers inside Windows once, then turn it on in Edit Config → Graphics. • Import from Parallels Desktop: bring your existing Windows virtual machines over with File → Import from Parallels Desktop. • Stability improvements.

macOS 27 support: new macOS virtual machines can set up their first account automatically and Linux virtual machines get a Secure Boot option (both need macOS 27 or later). Fixes Ubuntu virtual machine creation, license page language and a main window that could be resized too small.

Fixes for issues that could lose a suspended state or a snapshot, keep a Windows virtual machine from starting, or make the app quit unexpectedly. The app now shows when a virtual machine is suspended, and offers processor, memory and disk options that match your Mac.

Windows virtual machines now have sound, support snapshots taken while running (optionally with memory), and can be suspended to disk and resumed where you left off. Stability improvements and fixes.

Hand a virtual machine to an AI assistant. Turn on Automation in Settings, copy the address, and paste it into an assistant that speaks the Model Context Protocol, such as Claude Code. It can then start and stop virtual machines, take and restore snapshots, run a command inside a guest, and take a screenshot of the virtual machine's own screen. The server stays off until you turn it on, listens on this Mac only, and its address carries a key unique to your Mac. Disposable sandboxes. Clone a prepared virtual machine in about a second and at almost no disk cost, work in it, and let it expire into the Trash on its own. A snapshot before the assistant starts. Kyvenza takes one and reports its name back, so an unwanted change can be undone. Starting a virtual machine yourself does not take one. Isolated networking. A new setting gives a virtual machine no network adapter at all. Windows and Linux. Windows virtual machines can run automation commands once you have run the bundled driver installer inside the guest, and capturing a Windows screen no longer needs anything installed there. Linux virtual machines without a desktop environment can be captured too. Snapshots of Windows virtual machines are now incremental: the space one takes is fixed when you take it and no longer grows as you keep using the machine.

Windows virtual machines can share folders with your Mac. Add one under Edit Configuration > Shared Folders and it shows up inside Windows as a network drive. • Copy a file on your Mac and paste it inside Windows with Ctrl+V. Run Install-Kyvenza-Drivers again from the KYVENZA-DRIVERS disc first, so the guest tools are up to date, then close the display window and open it again. Folders are not supported, and files over 64 MB are better dragged than pasted. • Drag files from Finder onto a Windows machine's display window, or press Command-V there, to drop them on the Windows desktop. • When your Mac runs low on battery, running machines are protected automatically: Linux machines are suspended to disk and come back where they left off, while macOS and Windows machines are shut down gracefully after a warning. You can turn this off in Settings. • Fixed: right-clicking a machine in the list and choosing Delete or Clone opened an empty window, so neither could be completed. A few other dialogs could open empty in the same way and have been corrected. • Fixed: a machine could become unstartable after failing to resume from a suspended state. • Fixed: mixed Chinese and English text on the setup screens.

Windows virtual machines can now share the clipboard with your Mac. • Copy text or an image on either side and paste it on the other. Inside the machine, run Install-Kyvenza-Drivers from the KYVENZA-DRIVERS disc to install the guest tools, then turn on Clipboard in the machine's settings. • Sharing only happens while the display window is open, and the clipboard is read only at the moment the guest actually pastes. • Two settings that never did anything on Windows virtual machines have been removed: audio and shared folders. They were shown but had no effect, and removing them is more honest than leaving them there. • The Open Source Notices in About now cover the bundled SPICE guest agent, with its sources, patches, and build script published alongside this release.

Kyvenza now runs Windows 11 on ARM. • Create a Windows virtual machine from the same wizard you already use. You supply Microsoft’s official ARM64 installation image and a valid Windows licence; the wizard links to the official download page. • The drivers Windows needs are included. When setup stops at the network page, run Install-Kyvenza-Drivers from the KYVENZA-DRIVERS disc already in the machine — nothing to download separately. • TPM 2.0 and Secure Boot are on by default, so Windows 11 installs without registry workarounds. • Windows virtual machines support offline snapshots, cloning, and backup. Saving the state of a running machine remains available for macOS and Linux virtual machines. • The Open Source Notices in About now list every bundled component and link to the sources and build scripts for this exact release.

Deleting a virtual machine now moves it to the Trash by default, so you can put it back from Finder if you change your mind. When you need the disk space right away, tick "Delete permanently" in the confirmation dialog. The create wizard now checks how much memory this Mac has available and tells you before you start an installation that is likely to run out of room. Installing an operating system while the Mac is short on memory is a common cause of the guest freezing partway through. Linux virtual machines now switch to normal boot on their own once the operating system is installed, instead of starting the installer again. The Logs tab now recognises kernel crashes inside the guest and explains what happened and what you can do about it, rather than leaving you to read the stack trace. New virtual machines get a default name and a list icon that match the Linux distribution you picked. Fixed: deleting a virtual machine while it was running could quit the app unexpectedly. Running virtual machines can no longer be deleted or cloned. Fixed: the app could stay on screen without a window while it scanned the virtual machine folder on a slow or busy disk. Fixed: the virtual machine list did not update after a machine was started or stopped through the automation interface.

• Pause and resume: a running VM can be paused and picked up later from exactly where it left off. • Force stop: when a VM stops responding, you can cut its power from the menu on the Stop button. • New Diagnostics tab in Settings: run a system check and export a diagnostics bundle when you need to troubleshoot. • Audio controls per VM: speaker output and microphone are now separate switches. The microphone is off by default, and macOS asks for permission the first time a VM starts with it enabled. • The Logs tab now shows logs for the selected VM, and Linux VMs can turn on serial console logging to capture guest console output. • Clipboard sharing with Linux virtual machines: copy and paste text between your Mac and a Linux guest running spice-vdagent, while the VM display window is open. • Fixed Linux virtual machines showing a wrong IP address or none at all. The display page now shows the network mode and IP address, with one-click copy for the address or an ssh command.

• Smoother Linux VM display: the pointer now stays visible and moves fluidly across the entire VM window. • Sharper Linux console text — the display keeps your configured resolution and scales to fit the window. • More reliable Ubuntu ARM installation on Apple Silicon. • Stability and reliability improvements across the virtualization engine.
