This change is relevant to the new metadata class Targets.
In the specification, when describing the Targets metadata file format
and more precisely "TARGETPATH" (or targets containing the actual
target files) it's said:
"It is allowed to have a TARGETS object with no TARGETPATH elements.
This can be used to indicate that no target files are available."
If there is no "TARGETPATH" keys for the dictionary "targets", this
would mean that "Targets.targets" is {}.
Make sure we test for that.
See: https://theupdateframework.github.io/specification/latest/#targetpath
