Firecracker v0.7.0

Added

• Rate limiting functionality allows specifying an initial one time
  burst size.
• Firecracker can now boot from an arbitrary boot partition by specifying
  its unique id in the drive's API call.
• Block device rescan is triggered via a PUT /actions with the drive ID in the
  action body's payload field and the action_type field set to
  BlockDeviceRescan.

Changed

• Removed noapic from the default guest kernel command line.
• The action_id parameter is no longer required for synchronous PUT requests
  to /actions.
• PUT requests are no longer allowed on /drives resources after the guest
  has booted.

Fixed

• Fixed guest instance kernel loader to accelerate vCPUs launch and consequently
  guest kernel boot.
• Fixed network emulation to improve IO performance.
