PyShapeLib and Boolean Fields

[George]

Apologies if this isn't the right place for this question but the 
pyshapelib manual does mention the Thuban mailing lists as a point of 
contact.

I've been using pyshapelib for a while now and had no problems but now 
I'm getting an invalid type error when I tried to load a DBF. I think 
that this is because the shape file contains boolean fields and I've 
found...

which seems to suggest that the boolean type was added relatively late
to shapelib & dbflib.py doesn't have it listed as one of the types at
the bottom so I'm guessing this might be to blame?

If so does anyone have a version where support for the boolean field 
type has been added? I should add that I'm using the "packaged for 
windows" version, but that I've had a look at the original source 
version and that appears not to have it in either.
