asymptotically optimal mpz_jacobi?

[Paul Zimmermann]

       Hi,

on gmplib.org, one can read:

   "GMP 5 will be released as soon as it is ready. This release will make all
    major functions of GMP asymptotically optimal, including division, exact
    division, modular computation, etc."

Does "etc" also include mpz_jacobi?
