Hi, since `attr` is no longer used since v2.5.0, would you consider removing `attrs` from the dependencies? https://github.com/your-tools/tsrc/blob/6f2ffe29e93d179c48d1f2ff8a65e3e839c09167/poetry.lock#L3 https://github.com/your-tools/tsrc/blob/6f2ffe29e93d179c48d1f2ff8a65e3e839c09167/pyproject.toml#L22 Because the built package still includes `Requires-Dist: attrs (>=19.3.0,<20.0.0)`. Thanks & kind regards, Philippe
