Hi,
here:
https://sourceforge.net/projects/gretl/files/gretl4py/snapshots/
you'll find pre-release builds of gretl4py 0.62.
The most important change is the new dataset- and model-based testing API:
<python>
import gretl
d = gretl.get_data("denmark")
r1 = d.adf(2, [1])
m = gretl.ols("1 0 2 3 4").fit()
r2 = m.reset(squares_only=True)
</python>
The old API, i.e. obj.test(type: str, **kwargs), is still available, but
will be removed in version 0.7.
