Not sure if this is known, but I don't see tools.build v0.8.5 up on maven central. https://central.sonatype.dev/artifact/org.clojure/tools.build/0.8.4/versions.
As far as I know it's always been with github
Ya true, publishing to maven central is a new thing.
I might have forgotten to do that, will check later
Oh, I see what happened, I tagged by hand and then the artifact build failed because it was already tagged. Still working out the logistics…
