Hi,

I'm a bit puzzled: I had a code which worked fine using 
scipy.optimize.fmin_tnc with scipy 0.5.2. Unfortunately, since I upgraded 
scipy to 0.6.0, I hit some convergence issues...

Does it ring a bell to somebody? I understand I'm a bit vague for the moment 
(I did not look for a simple test case yet), but maybe somebody had this 
experience too. Besides the reverted output order, was there some significant 
algorithmic changes in fmin_tnc between 0.5.2 and 0.6.0?

Cheers.
