v1.8.3

1.8.3 (OCT 7, 2026)

✨ Features

• Nested virtualization – Add enable_nested_virtualization support for the EBS builder, with validation for supported instance families. (#679)

🐛 Bug Fixes

• Fix IAM instance profile propagation checks – Use the configured instance type and resolved subnet during the propagation dry-run, avoiding unrelated failures for ARM64 AMIs and accounts without a default VPC. Ensure the temporary role is detached during cleanup even if the check fails. (#700)
• Honor dedicated host placement – Pass the configured host_id to instance launches in the EBS surrogate, EBS volume, and instance builders. (#559)
