Introduce automatic versioning for pre-release usage

Hmm, I think I'm inclined not to do this just to avoid complicating what is currently a nicely simple build system. I definitely see the value, I just don't think...

Out of Memory: How to reduce the memory cost for calculating the derivatives wrt the input

Does this seem to be an OOM during runtime or an OOM during compilation? If the latter then it might be due to closing over a very large constant. If...

`NewtonChord` w/ `cauchy_termination=False` divergence test unhelfpul when `atol` is low

So I think this is expected. What is going on here is that `cauchy_termination=False` corresponds to a preference for failing a solve, rather than performing an expensive solve. In particular...

Support Events for BacksolveAdjoint
