Yes, your new version behaves in fact exactly like WolframAlpha - look at the following 2 examples:
30.012015 to 29.032015 --> 1 month 29 days
31.012015 to 29.032015 --> 1 month 29 days

Ooops, 2 different start days give the same result?
So for WolframAlpha (and for you) 30.Jan and 31.Jan are the same day?
(and there's no 30. or 31. Feb to which you could move forward from the Jan. start day)

Doesn't seem very logical to me, not even if WolframAlpha states it.

Added:
For end date 28.March it's even worse:
29.012015 to 28.032015 --> 1 month 28 days
30.012015 to 28.032015 --> 1 month 28 days
31.012015 to 28.032015 --> 1 month 28 days
Three different start dates, but all give the same result!
