Compare Source

Changed

• MSRV bumped to 1.80

• clap dependency unpinned.

Fixed

• gnuplot version is now correctly detected when using certain Windows binaries/configurations that used to fail

Added

• Async benchmarking with Tokio may be done via a tokio::runtime::Handle, not only a tokio::runtime::Runtime
