Diff since v1.27.0

• Dimensionless quantities now support iseven and isodd (#829).
• Quantities that have equal values and equal units now have the same hash (#833). For now, quantities that are equal (isequal) but have different units still have different hashes, see #379.

Diff since v1.22.1

• On Julia ≥ 1.9, dimensionless quantities can now be converted to ForwardDiff.Dual. This is important for compatibility with the SciML ecosystem and is provided via a package extension (#765).
• On Julia ≥ 1.9, @printf and @sprintf can now be used with Unitful quantities. The specified format is applied to the numeric part of the quantity and the unit is appended to that. This is provided via a package extension (#772).
• Certain unit conversions involving units that are defined using non-integer exponents no longer error (#783).
• uconvert now preserves the floating-point precision of quantities in a non-breaking way (#782).

• The behaviour to preserve the floating-point precision of quantities (#754, added in v1.22.0) is reverted because it is not compatible with IntervalArithmetic.jl (see #758). The feature will be added in a non-breaking way in a future release.

• Base.big can now be used with quantities (#755).
• Using Base.convert to convert to a unitless quantity no longer errors (#724).
