Sourced from pint's changelog.

0.16.1 (2020-09-22)

• Fix unpickling, now it is using the APP_REGISTRY as expected. (Issue #1175)

0.16 (2020-09-13)

• Fixed issue where performing an operation of a Quantity with certain units would perform an in-place unit conversion that modified the operand in addition to the returned value (Issues #1102 & #1144)
• Implements Logarithmic Units like dBm, dB or decade (Issue #71, Thanks Dima Pustakhod, Clark Willison, Giorgio Signorello, Steven Casagrande, Jonathan Wheeler)
• Drop dependency on setuptools pkg_resources to read package resources, using std lib importlib.resources instead. (Issue #1080)

0.15 (2020-08-22)

• Change Quantity and Unit HTML (i.e., Jupyter notebook) repr away from LaTeX to a simpler, more performant pretty-text and table based repr inspired by Sparse and Dask. (Issue #654)
• Add case_sensitive option to registry for case (in)sensitive handling when parsing units (Issue #1145)
• Implement Dask collection interface to support Pint Quantity wrapped Dask arrays.
• Started automatically testing examples in the documentation
• Fixed an exception generated when reducing dimensions with three or more units of the same type
• Fixed right operand power for dimensionless Quantity to reflect numpy behavior. (Issue #1136)
• Eliminated warning when setting a masked value on an underlying MaskedArray.
• Add sort option to formatting.formatter to permit disabling sorting of component units in format string
• Implements Logarithmic Units like dBm, dB or decade (Issue #71, Thanks Dima Pustakhod, Giorgio Signorello, Jonathan Wheeler)

0.14 (2020-07-01)

• Changes required to support Pint-Pandas 0.1.

0.13 (2020-06-17)

• Reinstated support for pickle protocol 0 and 1, which is required by pytables (Issue #1036, Thanks Guido Imperiale)
• Fixed bug with multiplication of Quantity by dict (Issue #1032)
• Bare zeros and NaNs (not wrapped by Quantity) are now gracefully accepted by all numpy operations; e.g. np.stack([Quantity([1, 2], "m"), [0, np.nan]) is now valid, whereas np.stack([Quantity([1, 2], "m"), [3, 4]) will continue raising DimensionalityError.
