From NEWS.md:

Breaking Changes

• Now vegas, suave, divonne, and cuhre wrap the 64-bit integers
  functions. The 32-bit integers functions are no more available. llvegas,
  llsuave, lldivonne, llcuhre are deprecated and will be removed at some
  point in the future. This change reduces confusion about the function to use.

New Features

• Now it is possible to vectorize a function in order to speed up its evaluation
  (see issue #10 and
  PR #11).
• The result of integration is wrapped in an Integral object. This is not a
  breaking change because its fields can be iterated over like a tuple, exactly
  as before.
