Feb 14, 2024
  • This is a bug fix release addressing the following issues:
  • [snapshots] Rollback of failed restore wrongly applies last snapshot #3362

New in Multipass 1.13.1 RC (Feb 8, 2024)

  • [snapshots] Rollback of failed restore wrongly applies last snapshot #3362
  • [regression] multipass aliases command throws segmentation fault #3383
  • Images used for snapcraft do not report pollinate data #3390
  • [regression] cannot connect to the multipass socket on Intel Mac #3399

New in Multipass 1.13.0 (Jan 11, 2024)

  • Introducing Snapshots:
  • This release includes the much sought after support for snapshots of instances! With this, you will be able to create an instance, configure it as you see fit, and then take a snapshot of it so you don't have to start from scratch in case something goes wrong with your instance and need to start over. For more information about snapshots, you can read the documentation here.
  • Other significant changes:
  • Multipass has moved to using Qt6 (version 6.2.4 to be exact). This fixes a number of bugs in Qt itself and also allows for PAC files for proxy support.
  • Rewrite of some parts of the cross platform SFTP server used for classic mounts to use std::filesystem instead of QFile. This avoids some bugs in Qt along with using more of the stdlib when we can.
  • Fetching of remote image information is more performant and will not block the client as before.

New in Multipass 1.11.1 (Feb 7, 2023)

  • Use better way to transfer SMB password to instance for native mounts
  • Call apt-get update before installing cifs-utils in the instance for native mounts

New in Multipass 1.11.0 (Jan 19, 2023)

  • There are a few significant additions to this release:
  • Native mounts that are more performant are now supported on some platforms/drivers. This is still considered experimental. The following describes which platform and driver combinations support this:
  • The qemu driver on both Linux and macOS (both Intel and M1/M2)
  • The hyperv driver on Windows
  • Note: On Windows, due to having to use SMB, your user's password is required every time a mount is necessary, including when starting an instance that already has a native mount defined. We are working on a way to make this better.
  • Notable bug fixes:
  • [qemu] daemon starting instance twice if triggered on startup (#2520)
  • sshfs_server not cleanly shut down when stopping an instance (#1132)
  • sshfs_server gets in tight loop if host mount directory is missing on instance start (#1677)
  • [gui] not reacting to primary instance being purged (#1241)
  • Broken process substitution for multipass launch command (#1589)
  • [lxd] Multipass not reacting correctly with internally shut down instances (#2672)
  • [mounts] Repeated id/gid mappings (#2665)
  • make multipass list --format csv|json|yaml output consistent (#2464)
  • List cpu count in multipass info (#1804)
  • multipass launch should allow --memory as a synonym of --mem (#2490)
  • How to define a native mount
  • When issuing the multipass mount command, pass the --type native option to the command line and Multipass will use the native mount if you are using a supported platform and driver combination. For example:
  • $ multipass mount --type native /Downloads foo:Downloads
  • multipass transfer now allows transferring directories recursively using the -r/--recursiveoption and allows making any missing parent directories in the instance using the -p/--parents option.
  • Instances now boot using UEFI allowing Multipass to support launching Ubuntu Core 20 and Core 22.
  • Blueprints now allow command aliases to be defined along with the ability to create a workspace for host/instance integration.

New in Multipass 1.10.0 (Jul 13, 2022)

  • There are some significant additions to this release:
  • Modifying instances is now supported. You can modify the number of cores, memory, and disk space allocated to an instance. Note that instances can only be modified when they are not running and disk space can only be increased. See https://multipass.run/docs/modify-an-instance#heading--set-the-cpu-ram-or-disk-of-an-instance for more information.
  • On Windows, Multipass now supports creating generation 2 virtual machines in Hyper-V along with disabling dynamic memory. These apply only to new instances launched and not existing instances.
  • Specifying mounts at launch time is now possible via multipass launch --mount.
  • It's now possible to use a URL when using the --cloud-init option in launch.
  • There are few enhancements to the multipass exec and multipass alias commands. See https://multipass.run/docs/exec-command and https://multipass.run/docs/alias-command respectively for details.
  • More highlights:
  • Launching an instance using the lxd driver will now use the general cloud image instead of the KVM image. This is due to the KVM kernel in the image having unfixed bugs. (#2491)
  • multipass transfer now handles a directory being a target. (#1165)
  • The Multipass icon is now shown in the "Windows Apps & Features" Multipass entry. (#2595)
