“+dfsg.N” and “+ds.N“ are a conventional way of extending a version string, when the Debian package's upstream source tarball is actually different from the source released upstream. The former is used when upstream's source release contains elements that do not satisfy the Debian Free Software Guildelines (DFSG) and hence may not be distributed as source in the Debian system, the latter (standing for “Debian Source”) is used when the modification are for other non-DFSG reasons. The changes should be documented in README.source.
