Bahne,
I am unaware of any changes to the inductor selection. We update our passive component database often and it may be possible this resulted in picking a different inductor based on the knob settings in the optimizer for the new design.
However, upon looking at the history, the output capacitor and compensation network have incurred some changes. For example, in October '13, we used only Rcomp, Ccomp but now we also use Ccomp2 in addition. This was based on feedback from the users where the phase margin was not sufficient in some cases.
It would be good to create designs again if you can for future use. I apologize for the inconvenience caused and we will notify you of any changes to device(s) in the future.
Please do let me know if you have any further questions or need any assistance.
Regards,
Amod Vaze
