ranisalt [1] filed a orphan request for otclient-git [2]:

The package has not been updated for the last two years, is out of date for almost three monts, even though the repository is actively developed (https://github.com/edubart/otclient/commits/master).

This package maintainer (edub4rt) is one of the original developers, but has been inactive for a long time and probably will not update the package anymore.
