v3.0.1.post0

This v3.0.1.post0 patch release includes additional infrastructure to support the automated building and publishing of manylinux wheels to PyPI.

All features are the same as the v3.0.1 patch release.

v3.0.1

This patch release includes the following changes:

Pull Requests Merged

1. PR 183 - Persist calendar when discarding cftime microsecond (@bjlittle)

For further details, see the v3.0.x GitHub Discussion.

v3.0.0

Adopts the latest cftime (v1.5) behaviour, including breaking changes.

• utime, julian_day2date and date2julian_day removed (#168).
• num2date method now returns a cftime.datetime by default, with options to override this (#168, #172).
• Improvements to type preservation during conversion (#164).

v2.1.5

This is a bugfix to restore the num2date and utime behaviour to that before cftime v1.1, which saw a change to return cftime.datetime objects by default (#165).

Also drops Python 2 since that is now out of support (#157).

The next cf-units release should be a major release, which explicitly adopts and documents cftime's post-1.1 behaviour referenced above.

v2.1.4

• This patch releases moves cython from a run requirement to a setup (build) requirement.
