README.rst 

gmpy2 is an optimized, C-coded Python extension module that supports fast
multiple-precision arithmetic.  gmpy2 is based on the original gmpy module.
gmpy2 adds support for correctly rounded multiple-precision real arithmetic
(using the MPFR library) and complex arithmetic (using the MPC library).

Version 2.3
-----------

gmpy2 2.3.0
-----------

gmpy2 2.3.0 supports Python 3.14 and free-threaded builds,

* Preliminary support for free-threaded builds.
* Fix behavior and memory leaks for contexts.
* Fix memory leaks for `mpfr` caching.
* Fix rounding error in float(mpz).
* Add missing methods to `mpz` and `mpq`.
* Fix round(mpz, ndigits) if ndigits is negative.
* Improved support for mixed `mpfr` and `mpc` arithmetic.

Version 2.2
-----------

gmpy2 2.2.2 (released as 2.3.0)
-------------------------------

* Many bug fixes.
* Initial support for free-threaded builds.

gmpy2 2.2.1
-----------

* Bug fix: use C int instead of C char for some internal code.
* Bug fix: add xmpz.bit_count method.

gmpy2 2.2.0
-----------

gmpy2 2.2.0 is now available with support for Python 3.7 to 3.13.

* Support for thread-safe contexts and context methods has been improved.
* Interoperability with Cython extensions has been updated.
* Extensive improvements have been made to the build and testing processes.
* Many bug fixes.
* Extensive documentation cleanup.

Availability
------------

gmpy2 is available at https://pypi.python.org/pypi/gmpy2/

gmpy2 is a C-coded Python extension module that supports multiple-precision arithmetic. It is the successor to the original gmpy module (supported only the GMP library). gmpy2 adds support for the MPFR (correctly rounded real floating-point arithmetic) and MPC (correctly rounded complex floating-point arithmetic) libraries.
