0.02 Mon Apr 12 13:11:16 1999

• made compatible with 5.004 and earlier releases
• Original version had a bug when char was unsigned, but it was not revealed by 'make test'. Squished the bug; smoothed out the signed/unsigned business; added test for the buggy condition.

0.03 Wed Jun 9 14:34:17 1999

• Added unpackeb(), ":all" tag.
• Eliminated the superfluous IBM390lib subdirectory.
• Smoothed out the signed/unsigned business some more.
• Corrected the package name in IBM390.xs.

0.04 Wed Jun 23 08:11:54 1999

• Made $warninv global.
• Further (final?) signed/unsigned improvements.
• Added validity checking and 'x' option to unpackeb.
• Added debugging option.

0.05 Tue Jul 20 14:43:17 1999

• Transitional release.
• pdi and pdo renamed to packed2num and num2packed.
• Added zoned2num and num2zoned functions.
• Added packeb function.
• Added zoned support to unpackeb.

0.06 Wed Jul 28 07:45:05 1999

• Removed separate functions for packed and zoned conversions.
• Removed $warninv.
• Diverged from IBM390p.

0.07 Tue Sep 7 13:16:47 1999

• Merged Perl and Perl/XS versions into one distribution with identical functions.
• Added packeb() and unpackeb() to Perl-only version.

0.08 Tue Sep 7 13:16:47 1999

• Added a dummy IBM390.pm to the top directory so that CPAN could find it. It includes the POD for the use of search.cpan.org.

0.10 Tue Oct 17 10:29:35 2000

• Changed 'sv_undef' to 'PL_sv_undef' to conform with current perl5 lingo. Otherwise identical to 0.09.

0.11 Fri Dec 15 12:45:21 2000

• Added "#include <stdio.h>" to IBM390lib.ccc (don't know how I missed that one!).
• Small cosmetic changes.

0.12 Mon Jan 15 08:51:47 2001

• Redesigned XS version to correct a bad memory leak. Thanks to Barry Roomberg and another user for pointing this out and providing test code. Unfortunately, I had to put a limit on the number of values returned by unpackeb, but it's fairly generous (4400).
• New e-mail address for yours truly.

0.14 Mon Mar 12 14:41:31 2001

• Modified Makefile.PL to see whether Perl is using sv_undef or PL_sv_undef and adjust things automatically.
• Small cosmetic changes.

0.15 Tue Apr 9 14:20:12 2002

• Corrected bug in asc2eb, eb2asc, and eb2ascp when translating empty strings.
• Added 'P' option to packeb (suggested by a requirement from Tony Maa).
• Added version function.

0.16 Tue Nov 18 08:44:02 2003

• Rewritten to pull the packeb.c code into the XS routine.
• Used "unsigned long" rather than "long long" to correct a bug when building under Windows.
• Math library (-lm) is no longer required.

0.17 Wed Dec 24 09:19:59 2003

• Added the SMF timestamp data type at the request of Champ Lee.

0.18 Mon Mar 15 14:02:30 2004

• Made performance improvements to the XS/C version: moved the translation tables into the C code, moved asc2eb etc. to the .xs file rather than .pm, avoided storage allocations.
• Added trailing blank/null suppression to unpackeb('E'...).
• Thanks are due to Jeffrey Horner for these suggestions.

0.19 Wed Jul 14 16:39:54 2004

• Corrected a bug in unpackeb's integer conversions. Thanks to Taavo Raykoff for pointing this out.

0.20 Wed Mar 9 08:17:03 2005

• Corrected memory leaks in CF_num2packed and CF_num2zoned. This was pointed out by a few people, but it seemed to appear only under Linux; anyhow, Chris Madsen came up with a good solution to the problem.

0.21 Wed Nov 2 13:30:50 2005

• Added '@' option to unpackeb at the request of Marc (CPAN bug 15461).

• Put the POD in a separate .pod file.
• Removed validpacked and validzoned.

0.23 Tue Aug 28 16:53:43 2007
