0.12.1 to 0.12.4 Datarange1d doesn't take datetime anymore

so in 0.12.1 i could declare a figure with xmin and xmax as datetime objects:

fig=Figure(x_axis_type=‘datetime’,x_range=(xmin,xmax))

``

In 0.12.4 this gives a Value error because the default x_range is a DataRange1d object.

I now need to do:

fig =Figure(x_axis_type=‘datetime’,x_range=Range1d(xmin,xmax))

``

Is it intentional?

“Shouldn’t” the range type automatically be set to Range1d when using a ‘datetime’ type axis? Or should I give seconds since epoch to the default DataRange1d ?
