Bug fixes:

Breaking Changes:

• Warning issued for systemd environments if cloud-init boot stages are
  called by PIDs other than the root process. It is expected that boot
  stages are only called by systemd units and not post-production scripts
  or tools.
• Introduce a performance optimization by sharing the python environment and setup costs across all four boot stages with a new cloud-init-main.service
