0.04 Sat Jun 8 2002

• last draft version before using h2xs

0.05 Sun Jun 9 2002

• original version; created by h2xs 1.20 with options

  -XA -n List::Compare

0.06 Wed Jun 12 2002

• documentation changes; POD broke

0.07 Thu Jun 13 2002

• documentation changes

0.08 Sat Jun 15 2002

• added method get_version()
• used non-idiomatic syntax for 'foreach' in hope of making module more backwardly compatible
• to free up memory, zeroed out %seenA and %seenB when no longer needed
• added method get_bag()
• inspired by Set::Scalar, used typeglob syntax to implement aliases for methods
• revised POD extensively

0.09 Sun Jun 16 2002

• added tests to test get_bag()
• implemented Carp module for warnings

0.10 Wed Jun 19 2002

• corrected one typo in documentation
• commented out # require 5.00562 and use warnings
• first version uploaded to CPAN

0.11 Thu Jun 20 2002

• corrected errors in POD that caused HTML to display incorrectly

0.12 Sat Jul 13 2002

• major expansion
• capability to accelerate processing of comparisons of 2 lists when only 1 comparison method is expected to be called
• capability to compare more than 2 lists at a time
• introduction of methods including:

  get_shared() get_nonintersection() print_subset_map() print_equivalence_map()

• not released to CPAN due to errors in README and Changes

0.13 Sat Aug 03 2002

• corrected documentation errors found in v0.12
• released to CPAN

0.14 Sun Aug 18 2002

• commented out 'use warnings;' to permit module to run on pre-5.6 versions
• corrected one error in POD
• removed e-mail addresses of authors of other modules from POD

0.15 Sat Sep 07 2002

• conformed CPAN addresses of other modules to new structure of search.cpan.org

0.16 Sat Mar 08 2003

• for each method which returned an array, added an analogous method which returns a reference to that array

0.17 Thu May 22 2003

• eliminated certain synthetic variables
• created List::Compare::SeenHash

0.18 Sun Jun 1 2003

• added methods member_which(), single_member_which()

0.19 Sun Jun 1 2003

• added methods member_any(), single_member_any()
• fixed annoying carping messages when running 'make test'

0.20 Fri Jun 6 2003

• updated documentation discussing changes since v0.17
• changed names of recently added methods to is_member_which(), is_member_which_ref(), are_members(), is_member_any(), are_members_any()

0.21 Sun Oct 26 2003

• added functional interface to list comparison functions: List::Compare::Functional; this required changes in List::Compare::Base::Accelerated and the creation of List::Compare::Base::_Engine

0.22 Sun Nov 23 2003

• corrected conceptual flaw in List::Compare::SeenHash so as to exclude values in a seen-hash mathematically equal to zero
• implemented 'unsorted' option for list comparisons

0.23 [Accidentally skipped.]

0.24 Sun Mar 28 2004

• first implementation of 'multiple accelerated' mode wherein user can request speedier processing of more than two lists when only one comparison among the lists is sought
• converted test suite to use Test::Simple

0.25 Sun Apr 4 2004

• continued implementation of 'multiple accelerated' mode; applied to List::Compare::SeenHash and List::Compare::Functional
• modification of interfaces to methods/functions are_members_which() and are_members_any throughout; items to be tested must be passed (by reference) as an anonymous array rather than as a flat list

0.26 Sun Apr 11 2004

• List::Compare::SeenHash and associated tests deprecated
• capacity to pass references to seen-hashes to constructor now transferred directly into List::Compare
• corrections to POD

0.27 Sun Apr 18 2004

• corrections to POD

0.28 Sun Apr 25 2004

• implementation of is_LdisjointR
• correction of error in tests of multiple-accelerated mode
• correction of error in internal subroutine argumentchecker_0
• further implication of deprecation of List::Compare::SeenHash is that all the code in List::Compare::Base::Regular, L:C:B:Accelerated, L:C:B:Multiple and L:C:B:Multiple::Accelerated is no longer shared between List::Compare and List::Compare::SeenHash and hence can be taken back into List::Compare; thereby eliminating the 'use base' calls from List::Compare.

0.29 Sun May 16 2004

• implementation of alternative ('Adlerian') interface wherein a single hash reference is passed to constructor or function

0.30 Fri May 21 2004

• documentation corrections only

0.31 Sun Aug 15 2004

• added methods get_unique_all() and get_complement_all(); added 3335 tests; repositioned most methods in List::Compare::Base::_Engine to List::Compare::Accelerated as they were no longer also being used in List::Compare::Functional; other internal code clean-up

0.32 Sun Sep 18 2005

• No changes in functionality. Distribution restructured so that modules are now underneath the 'lib/' directory.

0.33 Sun Feb 19 2006

• Documentation changes only. Support for List-Compare is now offered via dedicated mailing list.

0.34 Mon Nov 5 18:35:15 EST 2007

• Add require 5.6 to Makefile.PL.

0.35 Sun May 18 19:54:32 EDT 2008

• Fix bug reported by Charles Bailey. In object-oriented interface, two lists case, get_shared and get_shared_ref should default to get_intersection and get_intersection_ref.
• Complete overhaul of test suite. Tests are now grouped by interface in a more logical order.

0.36 Fri May 23 21:41:55 EDT 2008

• IO::CaptureOutput was mispositioned: should have been directly under t/ rather than under t/Test/.

0.37 Sat Jun 7 19:46:52 EDT 2008

• Tests refined and code refactored so as to achieve 100% subroutine, statement, branch and condition coverage by test suite as measured by Devel::Cover. Some cleanup of POD.
