Hi, Hilmar Preuße, and tony: Thanks for you guide!
I will keep the distribution tag "UNRELEASED" as it is for the sponsor. The debian/watch was modified to direct to apache archive site ,because: 1.Tag names from github are not well defined[1]. 2.Some github release even introduces nonexisted files[2]. I think the apache site will do a little more strict check before archiving. I uploaded again, please refer to mentors.debian.(Upload #2.)
