[stanislavlevin]

According to https://github.com/fmenabe/python-yamlordereddictloader

DEPRECATED: the Phynix/yamlloader project provide an improved version of this library with unit tests, performance improvements (by providing access to the C implementation of PyYAML) and is more actively developed. You should use it!

Please migrate from yamlordereddictloader.
