Packer - 1.9.0

(Unreleased)

NOTES:

• Breaking Change: Iteration fingerprints used to be computed from the Git SHA of the
  repository where the template is located when running packer build. This
  changes with this release, and now fingerprints are automatically generated
  as a ULID. This implies that continuing an existing iteration will require
  users to define the fingerprint in the environment manually in order to
  adopt this behaviour, otherwise, by default, a new iteration will be
  created. This does not impact workflows where the fingerprint was defined
  through the HCP_PACKER_ITERATION_FINGERPRINT environment variable, and
  these builds will work exactly as they did before.
  GH-12172

IMPROVEMENTS:

• core/hcp: Now, fingerprints used by HCP Packer are randomly generated ULIDs
  instead of a Git SHA, and a new one is always generated, unless one is
  already specified in the environment.
