Citing from https://docs.gitlab.com/ee/api/v3_to_v4.html
Since GitLab 9.0, API V4 is the preferred version to be used.
API V3 will be unsupported from GitLab 9.5, to be released on August 22, 2017. It will be removed in GitLab 9.5 or later.
This project is working with API v3 (libsaas_gitlab/service.py#L34). Is it going to be adapted to GitLab API v4?
