As with bashdb, the release name needs a little explanation.

The release name contains the target (and initial) version of GNU make that this code is forked off of; the release name also contains the version for the forked changes.

So remake-3.82+dbg0.8 is based off of GNU Make 3.82 it is version 0.8 in that series. remake-3.81+dbg-0.3 is based off of GNU Make 3.81 (version 0.3).
