[ODE] New release?

Why would you want to change the API in that way? 

For graphics programming it makes sense to choose the format of the
underlying data but for physics programming you might want to switch
from float to double or vice versa just to try out stability issues.
Changing a define and recompile is much better (imho) than having to
change all function calls.

What would happen if you intermingle float and double precision
commands, wouldn't half of the commands just be doing type conversions?
How would you chose what precision the underlying engine is using (still
with a define?)

Perhaps you just mean to add separate functions with f/d suffixes that
do automatic data type conversion to the underlying engine type? I can
see some reasons to extend the API but not to remove the current way of
easily going between float and double precision without changing
application code. Perhaps there is some previous discussions of the
topic? I couldn't find a search interface for the mailing list, sorry.
