This release ensures dependency on `openapi-spec-validator<=0.4.0`, so now it is safe to
 run `poetry update` in projects, which depends on `rororo==3.0.1`. Previously, 
 `poetry update` have been installed latest `openapi-spec-validator==0.5.1` and as side-effect
 introduce `ImportError: cannot import name 'default_handlers' from 'openapi_spec_validator'`
 to the project :(
