1.16.0

Multipass version 1.16.0

We're pleased to announce Multipass 1.16.0, where the entire code base became fully open source! This is a consolidation release, bringing a ton of improvements to our GUI, fixes to the Multipass daemon/service, as well as important security enhancements.

Notices 📣

• Fully open source. Previously proprietary bits for Windows and macOS are now part of this repository.
• Our documentation has been migrated to ReadTheDocs and included in this repository.
• LXD and libvirt drivers are being deprecated, along with blueprints. The plan is to remove them in the next feature release.
• This is also likely to be the last release that will support macOS 13.

Spotlight 🌟

• Custom image launch! It is now supported on macOS and Windows too (with file:// or https:// URLs).
• GUI improvements:
  • Facilitate reusing launch configurations with a button to "Launch and configure next"
  • Support zoom in the terminal (use Ctrl or ⌘ together with +, -, or 0)
• Support the QEMU driver on ARM Linux hosts

Other highlights ✨

• Start VMs with the "Open shell" button
• Remember window size + better default sizes
• Improve copy-paste support
• Improve gRPC security with standard mTLS
• Update almost all our dependencies and move some more to Vcpkg
• Fix 5 different crash conditions (#3978, #4004, #4006, #4010, #4016)
• Fix issues with mounts, file transfer, and SSH (#3902, #3971, #3959, #4007)

See also the v1.16.0 milestone for more details.
