Release of GNU MPC 1.1.0

[Andreas Enge]

We are pleased to announce the release of GNU MPC 1.1.0, a C library for the
arithmetic of complex numbers with arbitrarily high precision and correct
rounding of the result. GNU MPC extends the principles of the IEEE-754
standard for fixed precision real floating point numbers to complex numbers,
providing well-defined semantics for every operation. At the same time, speed
of operation at high precision is a major design goal.

Version 1.1.0 can be downloaded together with its GnuPG signature from the
GNU web site as
   https://ftp.gnu.org/gnu/mpc/mpc-1.1.0.tar.gz
   https://ftp.gnu.org/gnu/mpc/mpc-1.1.0.tar.gz.sig

Bug reports and other comments may be addressed to the mailing list at
   https://lists.gforge.inria.fr/mailman/listinfo/mpc-discuss ;
a previous subscription to the list is not required (but the moderation
may take a bit longer then).

Noteworthy changes include the following:
  - Minimally required library versions: GMP 5.0.0 and MPFR 3.0.0
  - Fixed issues with MPFR 4.0.0
  - New functions: mpc_cmp_abs, mpc_rootofunity
  - Improved speed for corner cases of mpc_asin, mpc_sin, see
    http://lists.gforge.inria.fr/pipermail/mpc-discuss/2013-December/001266.html
  - Rewrite of the testing framework
  - New mpcbench tool, used with "make bench"
  - Fixed handling of over- and underflows with directed rounding in the
    "other direction" for mpc_cos, mpc_sin, mpc_exp and mpc_pow, see
    http://lists.gforge.inria.fr/pipermail/mpc-discuss/2015-March/001336.html
  - Fixed a bug in mpc_atan(0,y) with |y| near 1, see
    http://lists.gforge.inria.fr/pipermail/mpc-discuss/2017-March/001404.html

Happy hacking,

Andreas Enge and Paul Zimmermann
