  * Sync test files with Math-BigInt-1.999719.

2016-04-22 v1.50 pjacklam
  * Sync test files with Math-BigInt-1.999718.

2016-01-03 v1.49 pjacklam
  * Sync test files with Math-BigInt-1.999714.

2015-12-31 v1.48 pjacklam
  * Sync test files with Math-BigInt-1.999713.

2015-12-14 v1.47 pjacklam
  * Add patch from Gregor Herrmann (GREGOA) based on code by Dana Jacobsen
    (DANAJ) to fix problems with the new() method when Perl is compiled with
    support for 64-bit integers, but on platforms when the underlying OS is
    32-bit (CPAN RT #71548).

2015-12-03 v1.46 pjacklam
  * Add patch from Dana Jacobsen (DANAJ) and add new test file
    't/mbi-from-big-scalar.t' regarding CPAN RT #103517.
  * Fix spelling in GMP.xs ('modifing' -> 'modifying').
  * Whitespace/formatting in t/bigintg.t to make it more readble (for me, at
    least) and more in accordance with the 'perlstyle' manpage.

2015-11-09 v1.45 pjacklam
  * Sync test files with Math-BigInt-1.999709.
  * Required version of Test::More is 0.47.

2015-10-29 v1.44 pjacklam
  * Sync test files with Math-BigInt-1.999707.
  * Update the README file.
  * Remove the files INSTALL and LICENSE 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.
  * Required version of Math-BigInt is now 1.999706.
  * Add 'Test::More' 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.

2015-09-21 v1.43 pjacklam

 CHANGES
  * Add changes for the newest release.
  * Reorder change entries into descending chronological order.
 lib/Devel/CheckLib.pm
  * Update bundled Devel::CheckLib from v1.01 to v1.03.

    up until v1.32, but has been wrong since then.
