This is not advisable in my mind because we don't have nearly enough  
developer resources to start having 2 maintained branches of NumPy.   
The expectation that bug-fixes and other improvements will be  
happening on two different release tracks of NumPy is just not  
realistic right now.

I was only mildly supportive of making another ABI compatible  
release.   The resistance to my approach has dampened my enthusiasm  
for doing the work necessary to make it happen.    That's quite O.K.  
though.   If David or somebody else wants to make a 1.4.1 release that  
is ABI compatible with the 1.3 series then great.

I will just work on trunk and assume that the next release will be ABI  
incompatible.   At this point I would rather call the next version 1.5  
than 2.0, though.  When the date-time work is completed, then we could  
release an ABI-compatible-with-1.5  version 2.0.    My view of the  
timeline for the 1.5 release is the end of February.
