Changes in version 1.3.1, released in December 2022:

stdio.h.
Changes in version 1.3.0 ("Ipomoea batatas"), released in December 2022:
- New function: mpc_agm

corresponding to MPFR_RNDA on the designated real or imaginary part.
- New experimental ball arithmetic.
- New experimental function: mpc_eta_fund
- Bug fixes:
- mpc_asin for asin(z) with small |Re(z)| and tiny |Im(z)|

the same real and imaginary part, and the exponent is an even
positive integer
- mpc_fma: the returned 'int' value was incorrect in some cases (indicating
whether the rounded real/imaginary parts were smaller/equal/greater
than the exact values), but the computed complex value was correct.
