Difference between releases

Hi, Sorry if this has been asked before, but I was wondering, what is the difference between the https://github.com/FRRouting/frr/releases/tag/frr-6.0.2 <https://github.com/FRRouting/frr/releases/tag/frr-6.0.2> release and the https://github.com/FRRouting/frr/releases/tag/debian%2Ffrr-6.0.2-1 <https://github.com/FRRouting/frr/releases/tag/debian/frr-6.0.2-1> release ? The debian package provided for the first one seems to be the 6.0.2-0 version. Is the second one newer ? If so, why are there no package download available ? Thanks ! Antoine Joubert
