Dear maintainer(s), I noticed a regression in rrdtool-1.7.0 which I reported upstream, see https://github.com/oetiker/rrdtool-1.x/issues/794 for details. Upstream fixed the problem. Please consider a rev bump to include https://github.com/oetiker/rrdtool-1.x/commit/e1bddaf532ad29cf660318955875b1183000d850.
If I understand correctly, this issue is fixed in 1.7.2, which is in tree and stable.
