Version 1.0.2, "Fagus silvatica", released in January 2014, comes with the following bug fixes:

Fixed
mpc_atan
,mpc_atanh
for (+0, +1) 
Fixed
mpc_log10
for purely imaginary argument
Version 1.0.1, "Fagus silvatica", released in September 2012, comes with the following bug fixes:
 Switched to automake 1.11.6, see CVE20123386

#14669:
Fixed extraction of
CC
fromgmp.h

Fixed case of intermediate zero real or imaginary part in
mpc_fma
, found by hydra withGMP_CHECK_RANDOMIZE=1346362345
Version 1.0, "Fagus silvatica", released in July 2012, comes with the following new features:
 First release as a Gnu package
 Licence change towards LGPLv3+ for the code and GFDLv1.3+ (with no invariant sections) for the documentation
 100% of all lines are covered by tests

Renamed functions
mpc_mul_2exp
tompc_mul_2ui
mpc_div_2exp
tompc_div_2ui
 0^0, which returned (NaN,NaN) previously, now returns (1,+0)
 Removed compatibility with K&R compilers, which was untestable due to lack of such compilers

New functions
mpc_log10
mpc_mul_2si
,mpc_div_2si

Speedups
mpc_fma

Bug fixes

mpc_div
andmpc_norm
now return a value indicating the effective rounding direction, as the other functions 
mpc_mul
,mpc_sqr
andmpc_norm
now return correct results even if there are over or underflows during the computation 
mpc_asin
,mpc_proj
,mpc_sqr
: Wrong result when input variable has infinite part and equals output variable is corrected 
mpc_fr_sub
: Wrong return value for imaginary part is corrected

The second Mpfr/Mpc developer meeting has been held in Bordeaux from June 25 to 27, 2012.
Version 0.9, "Epilobium montanum", released in February 2011, comes with the following new features:

New functions

mpc_set_dc
,mpc_set_ldc
,mpc_get_dc
,mpc_get_ldc
for converting between mpc type variables and C variables of typedouble _Complex
orlong double _Complex

mpc_sin_cos
, computing simultaneously the sine and cosine


Speedups

mpc_pow_si
through binary exponentiation 
mpc_pow_z
when the exponent fits in a long 
mpc_tan
through the use ofmpc_sin_cos


Bug fixes
 trigonometric functions: infinite loop due to overflow for large arguments

exp
: close to infinite loop for argument close to 0 
sqrt
: close to infinite loop for argument close to 1 
add_si
: replaced macro by function, since the macro evaluated the same expression twice

Logging feature for debugging
./configure enablelogging
#include "mpclog.h"
instead of#include "mpc.h"
 Minimally required library versions: gmp 4.3.2, mpfr 2.4.2

: along branch cut 
norm
: infinite loop in case of overflow 
ui_div
,div
,fr_div
: handling of division by 0 and infinities following the example code of the C99 standard  compilation with g++
