After updating to 3.5 version I've started to receive an incorrect exception while using safeLoad on this file: https://github.com/wikimedia/restbase/blob/master/sys/post_data.yaml

The exception is: YAMLException: duplicated mapping key at line 24, column 1:\n \n ^\n at generateError

Seems like empty lines are considered as mapping keys now, which is clearly incorrect.
