v2.0.0

Code adjusted to support the significant changes made in the https://github.com/actions/runner-images source repository. Managed Images are now directly created, without a .vhd intermediary step.

Work done for 99.9% by @erik-de-bont , great job and thank you!

v1.0.0

The codebase that supported yml and hcl template files, creating vhd's. Done as preparation for v2.0.0 where packer will create the managed image directly.
