Release tag 2.1.0 compiles as 2.0.6

[dcolley]

Question Is 2.1.0 available?

I'm trying to compile 2.1.0, but the version reports

./target/release/parallel --version
parallel 2.0.6-d56e95b32f5

on telemetry I see none of the nodes run 2.1.0...?

I think they do not have node change? Only runtime code changing.
