Bug introduced in 11.1 or earlier and fixed in 11.2
I have updated to Mathematica 11.1 and I am shocked to see that the
Series function now works differently:
If I enter
it will return
which is just weird. In the old versions, it would correctly return
I get that it now tries to return the leading non-trivial term, but this "feature" breaks a number of functions that I have written over the last years and use in my daily work. Does anybody know if there is a quick way to make Series work as it used to in older versions? Did anybody actually see this in any changelog? Because I for sure haven't...
