There's a ChangeLog entry from the day before yesterday:

	* doc/gmp.texi: Undocument mpz_array_init.

I take it Torbjörn really wants to deprecate this function.

Are you using it in mpfr?

One can still use mpz_realloc2, which can be viewed as an allocation
hint to the gmp implementation (so in mini-gmp, it's harmless but also
mostly useless, due to the frequent use of mpz_swap).
