There is a Pr that updates the code/tests to pass against the Dancer2 
release.
Hopefully Yanick has time to review/release.

The HTTP protocol deals with octects, so the request and response data 
has to
be decoded/encoded somewhere. There is also no consistency between
the available serializers' deserialize/serialize methods; take the 
various YAML modules
as an example:
   * YAML::Dump() gives characters
   * YAML::XS::Dump gives octets
[ Which is why Dancer2 no longer uses YAML::Any ]. Since you need to end 
up with octets
(or byte strings) in the response body, it made sense to define that as 
the expectation
when something was serialized.

Hope that helps,
