libyaml-perl (1.30-1) unstable; urgency=medium

  YAML 1.30 sets the default for $YAML::LoadBlessed to undef (false) in order
  to avoid loading untrusted objects, which can be a security vulnerability.

  Cf. http://blogs.perl.org/users/tinita/2020/01/making-yamlpm-yamlsyck-and-yamlxs-safer-by-default.html
  for background information and hints for handling this change.
