1.3004 2018-04-17
* The tests now require Test::More version 0.88 or newer.
* Sync test files with Math-BigInt.
* Add test files t/release-test-version.t, t/release-portability.t, and
t/release-cpan-changes.t.
* Use a MANIFEST.SKIP file based on the default file in the ExtUtils-Manifest
distribution.
* Format CHANGES according to CPAN::Changes::Spec.
* Convert test file t/02pod.t to t/release-pod.t and t/03podcov.t to
t/release-pod-coverage.t.
1.3003 2017-01-11 pjacklam
* Fix syntax for required version of Math::BigInt::Lib.
* Better checking of POD coverage.
* Sync test files with Math-BigInt-1.999808.
* _from_hex() now accepts input without a "0x" prefix.
* _from_bin() is more now efficient as it utilises the fact that
Math::Pari::_hex_cvt() assumes the input is binary if the strings is
prefixed by "0b".
* Implement _to_hex(), _to_oct(), and _to_bin() for conversion to hexadecimal,
octal, and binary without prefix.
* Fix _nok() to work around a bug in Math::Pari::binomial(). It doesn't
correctly handle cases where both n and k are very large.
* Correct a few cases where non-OO syntax was used, e.g., "$x = _one();"
should be "$x = $class -> _one();".
* _inc() and _dec() now uses post-increment and post-decrement, respectively,
rather than adding or subtracting one.
* In test file t/01load.t, display the PARI library version number.
1.3002 2016-12-03 pjacklam
* Use ExtUtils::MakeMaker rather than Module::Install in Makefile.PL
* Remove author information in LICENSE file.
1.3001 2016-11-23 pjacklam
* Sync test files with Math-BigInt-1.999801. Add t/mbi_rand.t, t/mbimbf.t,
and t/mbimbf.inc since these are included in the test suite for the other
backend libraries (GMP and Pari).
* Add _nok() by using Pari's binomial() function.
* Add _lcm() by using Pari's lcm() function.
1.3000 2016-11-15 pjacklam
* Sync test files with Math-BigInt-1.999800.
* Math::BigInt::Pari is now a subclass of Math::BigInt::Lib, so remove pure
Perl methods from Math::BigInt::Pari that are implemented in the superclass
Math::BigInt::Lib. The methods removed are _modinv() and _log_int(). The
version of _log_int() implemented in Math::BigInt::GMP was buggy anyway.
* Add methods _str() and _set(), and correct _num() method.

1.23 2015-11-22 pjacklam
* Sync test files with Math-BigInt-1.999709.
* In v1.22 the required version of Math-BigInt was set to 1.999703, but it
should have been 1.999706. The required version is now 1.999709.
* Correct error in CHANGES file.
1.22 2015-11-09 pjacklam
* Sync test files with Math-BigInt-1.999709.
* Update the README file.
* Remove the LICENSE file as this information is already covered in the file
README.
* Replace 'use vars ...' with 'our ...'. We require a Perl newer than 5.6.0
anyway.
* Move 'Test::More' from 'build_requires' to 'test_requires' in Makefile.PL.
* Enable 'use warnings'. We require a Perl newer than 5.6.0 anyway.
* Add 'assertlib.*\.exe' to MANIFEST.SKIP, since make generates temporary
files like 'assertlibzxjE4WfG.exe' on Cygwin.
1.21 2015-09-21 pjacklam
* Sync test files with Math-BigInt-1.999703.

t/*.t
* Add "use warnings" to test scripts, since Perl 5.6.2 is required anyway,
and "use warnings" was introduced in Perl 5.6.1.
* Modified test scripts so the difference between the test files in the
Math-BigInt distribution and the backend distributions are as few and as
small as possible. This makes for easier release management.
1.18 2014-04-03 pjacklam

* Math::BigInt::GMP now requires Math::BigInt v1.997 (Peter John Acklam).
* Include "^MYMETA\.(yml|json)\z" in MANIFEST.SKIP. Whereas META.* are
generated by the distribution author at packaging time, MYMETA.* are
generated by the end user at configure time after any dynamic
dependencies are known. (Peter John Acklam)
* Updated common test files from the Math::BigInt distribution. (Peter
John Acklam)

giving diagnostics useful for bug tracking (Peter John Acklam).
* Rename pod.t to 02pod.t and pod_cov.t to 03podcov.t and use more generic
code (Peter John Acklam).
* Clean up whitespace (Peter John Acklam).

- testsuite from MBI v1.60 - 4061 tests
- prerequisite fixed
- _copy() uses $zero instead of PARI(0) - benchmark for full BigInt copy():
copy: 6 secs ( 5.16 usr + 0.04 sys = 5.20 CPU) @ 23649.23/s (n=122976)
copy: 5 secs ( 5.19 usr + 0.06 sys = 5.25 CPU) @ 27047.05/s (n=141997)
- digit() now uses a method that scales much better when extracting digits
counting from the right side ($n > 0)
- likeweise, _inc and _dec use $one instead of PARI(0). Benchmark over
Math::BigInt->bdec() and binc() (not just _inc() and _dec()!):
1.08, 100 and 1000 digit numbers (speed is largely irrel. of number size):
dec 100: 4 secs ( 5.11 usr + 0.06 sys = 5.17 CPU) @ 17412.57/s (n=90023)
dec 1000: 6 secs ( 5.17 usr + 0.08 sys = 5.25 CPU) @ 17147.24/s (n=90023)

1.08 2002-03-23 Tels
- testsuite from MBI v1.55 - 3881 tests
- prerequisite fixed
1.07 2002-02-21 Tels
- Math::Pari has _hex_cvt(), which makes from_hex() fast, but doesn't have
something for from_bin(). Now _from_bin() repacks the input as hex number
and then passes it to _hex_cvt().
- tests from Math::BigInt v1.51
- replaced _core_lib() by config()->{lib}
1.06 2002-02-10 Tels
- _lsft() and _rsft() do now bases != 2, too
- tests are now from v1.50
- added _fac() for faster factorial() (used from MBI v1.50 onwards)

1.03 2001.09.02 btrott
- Incorporated Tels's changes: no longer need to EXPORT_OK functions;
added empty import method.
- Added _as_hex and _as_bin implementations for Math::Pari integers,
to support as_hex and as_bin Math::BigInt methods.
1.02 2001.08.05 btrott
- Added _gcd method; uses PARI library function to return gcd.
- Incorporated Tels's changes: _copy() is now linear; _is_zero,
_is_one, is_even, and is_odd now use PARI library functions
rather than overloaded ops and should thus be faster. Also
added new tests from Math::BigInt 1.40.
1.01 2001.07.14 btrott
- Incorporated Tels's changes per calling args to plugin methods
(now class is *always* the first arg, so no more checking).
Fixed some tests per Math::BigInt changes.
1.00 2001.07.11 btrott
- Initial release.
