v2.1.3

This patch release includes the following changes:

• Unpin numpy<1.17.0 (#154)

v2.1.2

This patch release includes the following changes:

• Fix to deal with non-Unit equality (#150, #149)
• Fixes to setup.py, primarily for correctly setting __NUMPY_SETUP__ on __builtins__ (#153, #152, #151)

v2.1.1

• Added a UDUNITS2 -> [La]TeX converter. cf_units.tex.tex(unit_string)

  

• In order to solve the above, a formal UDUNITS2 grammar and a private parser API was added (#140)

• Support for unicode units (e.g. cf_units.Unit('π m²')) (#135, #137)

• Replaced use of private _Unit factory function (#131)

• Improve py38 compatibility (#142)

• Better UDUNITS2 exception handling for py3 (#136)

• Allow pip install without needing numpy pre-installed (#145)

v2.1.0

Allow setup.py without numpy being pre-installed. (#145)

Fixes issue #144.

v2.0.2

cf_units was renamed to cf-units for broader consistency with the scientific python naming practices

v2.0.1

Fix source tar-ball distribution, which was missing necessary cython files.

v2.0.0

Technically, this release should have no breaking changes between v1.x and v2.x.

However, the major change in this release is that udunits is now wrapped via cython, not ctypes. This is in response to costly import times being experienced on distributed filesystems such as Lustre (where gcc was being called to identify the libudunits.so path).

This means that the cf_units/site.cfg is now no longer used to identify the location of libudunits, and standard LD library path definitions may be used instead.

v1.2.0

• Use succinct unit string for str (#79)
• Handle reference time units of months & years appropriately (#72)

v1.1.3

Fix for num2date/date2num allowing support for multi-dimensional arrays.

v1.1.2

Bug fix: #66
Ensure dates are rounded to nearest second when using netcdf4-python. The netcdf4-python behaviour changed between v1.1.1 and 1.2.2.
This release is insulated from that change.
