• update apns4erl - by lazedo

• HELP-16363: test blackhole bindings after AMQP disconnect - by James Aimonetti

• PISTON-1137: Fixes inaccurate stack trace. - by Roger Neate

  If an exception is caught within the kvm_message:prepend_and_notify/5 function, the correct stack trace was potentially overwritten by an exception occuring within the kvm_message:remove_malform_vm/2 function. The stack trace is now captured before calling that function.
