I apologize for the mis communication that has occurred here.   I did  
not understand that there was a desire to keep ABI compatibility with  
NumPy 1.3 when NumPy 1.4 was released.    The datetime merge was made  
under that presumption.

I had assumed that people would be fine with recompilation of  
extension modules that depend on the NumPy C-API.    There are several  
things that needed to be done to merge in new fundamental data-types.

Why don't we call the next release NumPy 2.0 if that helps things?     
Personally, I'd prefer that over hacks to keep ABI compatibility.   It  
feels like we are working very hard to track ABI issues that can also  
be handled with dependency checking and good package management.
