You are correct! Evaluates the integral in 8.04. Fails to evaluate the integral in 9.01. Looks like a bug.

Has anybody encountered the same problems with solving integrals in Ver. 9 as I did?
Here a very simple example:
Integrate[D[f[x], x] / f[x], {x, 0, T}]
Version 8.04 gives the correct results:
Log[f[0]] + Log[f[T]]
In Version 9.00 as well as 9.01 this integral can't be solved. With more complicated integrals I had the same problems. Version 8 gives a solution, Version 9 doesn't!
Could some other Version 9 users try it.
