== 1.3 / 2014-MM-DD
* Bugs fixed:
* Fixed an error for bin/ldiff --version.
* Force Diff::LCS::Change and Diff::LCS::ContextChange to only perform
equality comparisons against themselves.
* Tooling changes:
* Added SimpleCov and Coveralls support.
* Change the homepage (temporarily) to the GitHub repo.
== 1.2.5 / 2013-11-08
* Bugs fixed:
* Comparing arrays flattened them too far, especially with Diff::LCS.sdiff.
https://github.com/halostatue/diff-lcs/pull/23
== 1.2.4 / 2013-04-20
* Bugs fixed:
* A bug was introduced after 1.1.3 when pruning common sequences at the start
of comparison. Paul Kunysch (@pck) fixed this in pull request 18. Thanks!
https://github.com/halostatue/diff-lcs/pull/18
* The Rubinius (1.9 mode) bug in rubinius/rubinius#2268 has been fixed by the
Rubinius team two days after it was filed. Thanks for fixing this so quickly!
https://github.com/rubinius/rubinius/issues/2268
* Switching to Raggi's hoe-gemspec2 for gemspec generation.
== 1.2.3 / 2013-04-11
* Bugs Fixed:
* The new encoding detection for diff output generation (added in 1.2.2)
introduced a bug if the left side of the comparison was the empty set.
Originally found in rspec/rspec-expectations#238 and
rspec/rspec-expectations#239. Jon Rowe developed a reasonable heuristic
(left side, right side, empty string literal) to avoid this bug.
https://github.com/rspec/rspec-expectations/pull/238
https://github.com/rspec/rspec-expectations/pull/239
* There is a known issue with Rubinius in 1.9 mode reported in
rubinius/rubinius#2268 and demonstrated in the Travis CI builds. For all
other tested platforms, diff-lcs is considered stable. As soon as a suitably
small test-case can be created for the Rubinius team to examine, this will be
added to the Rubinius issue around this.
https://github.com/rubinius/rubinius/issues/2268
https://travis-ci.org/halostatue/diff-lcs/jobs/6241195
== 1.2.2 / 2013-03-30
* Bugs Fixed:
* Diff::LCS::Hunk could not properly generate a difference for comparison
sets that are not US-ASCII-compatible because of the use of literal regular
expressions and strings. Jon Rowe (JonRowe) found this in
rspec/rspec-expectations#219 and provided a first pass implementation in
diff-lcs#15. I've reworked it because of test failures in Rubinius when
running in Ruby 1.9 mode. This coerces the added values to the encoding of
the old dataset (as determined by the first piece of the old dataset).
https://github.com/rspec/rspec-expectations/issues/219
https://github.com/halostatue/diff-lcs/pull/15
* Adding Travis CI testing for Ruby 2.0.
== 1.2.1 / 2013-02-09
* Bugs Fixed:
* As seen in https://github.com/rspec/rspec-expectations/pull/200, the
release of Diff::LCS 1.2 introduced an unnecessary public API change to
Diff::LCS::Hunk (see the change at
https://github.com/rspec/rspec-expectations/commit/3d6fc82c for details).
The new method name (and behaviour) is more correct, but I should not have
renamed the function or should have at least provided an alias. This
release restores Diff::LCS::Hunk#unshift as an alias to
#merge. Note that the old #unshift behaviour was incorrect and will not be
restored.
== 1.2.0 / 2013-01-21
* Minor Enhancements:
* Added special case handling for Diff::LCS.patch so that it handles patches
that are empty or contain no changes.
* Added two new methods (#patch\_me and #unpatch\_me) to the includable
module.
* Bugs Fixed:
* Fixed issue #1 patch direction detection.
https://github.com/halostatue/diff-lcs/issues/1
* Resolved issue #2 by handling string[string.size, 1] properly (it returns
"" not nil). https://github.com/halostatue/diff-lcs/issues/2
* Michael Granger (ged) fixed an implementation error in Diff::LCS::Change
and added specs in pull request #8. Thanks!
https://github.com/halostatue/diff-lcs/issues/8
* Made the code auto-testable.
* Vít Ondruch (voxik) provided the latest version of the GPL2 license file in
pull request #10. Thanks! https://github.com/halostatue/diff-lcs/issues/10
* Fixed a documentation issue with the includable versions of #patch! and
#unpatch! where they implied that they would replace the original value.
Given that Diff::LCS.patch always returns a copy, the documentation was
incorrect and has been corrected. To provide the behaviour that was
originally documented, two new methods were added to provide this
behaviour. Found by scooter-dangle in issue #12. Thanks!
https://github.com/halostatue/diff-lcs/issues/12
* Code Style Changes:
* Removed trailing spaces.
* Calling class methods using '.' instead of '::'.
* Vít Ondruch (voxik) removed unnecessary shebangs in pull request #9.
Thanks! https://github.com/halostatue/diff-lcs/issues/9
* Kenichi Kamiya (kachick) removed some warnings of an unused variable in
lucky pull request #13. https://github.com/halostatue/diff-lcs/issues/13
Thanks!
* Embarked on a major refactoring to make the files a little more manageable
and understand the code on a deeper level.
* Adding to http://travis-ci.org.
== 1.1.3 / 2011-08-27
* Converted to 'hoe' for release.
* Converted tests to RSpec 2.
* Extracted the body of htmldiff into a class available from
diff/lcs/htmldiff.
* Migrated development and issue tracking to GitHub.
* Bugs fixed:
- Eliminated the explicit use of RubyGems in both bin/htmldiff and bin/ldiff.
Resolves issue 4 (https://github.com/halostatue/diff-lcs/issues/4).
- Eliminated Ruby warnings. Resolves issue 3
(https://github.com/halostatue/diff-lcs/issues/3).
== 1.1.2 / 2004-10-20
* Fixed a problem reported by Mauricio Fernandez in htmldiff.
== 1.1.1 / 2004-09-25
* Fixed bug #891:
http://rubyforge.org/tracker/?func=detail&atid=407&aid=891&group_id=84
* Fixed a problem with callback initialisation code (it assumed that all
callbacks passed as classes can be initialised; now, it rescues
NoMethodError in the event of private :new being called).
* Modified the non-initialisable callbacks to have a private #new method.
* Moved ldiff core code to Diff::LCS::Ldiff (diff/lcs/ldiff.rb).
== 1.1.0 / -
* Eliminated the need for Diff::LCS::Event and removed it.
* Added a contextual diff callback, Diff::LCS::ContextDiffCallback.
* Implemented patching/unpatching for standard Diff callback output formats
with both #diff and #sdiff.
* Extensive documentation changes.
== 1.0.4 / -
* Fixed a problem with bin/ldiff output, especially for unified format.
Newlines that should have been present weren't.
* Changed the .tar.gz installer to generate Windows batch files if ones do not
exist already. Removed the existing batch files as they didn't work.
== 1.0.3 / -
* Fixed a problem with #traverse\_sequences where the first difference from the
left sequence might not be appropriately captured.
== 1.0.2 / -
* Fixed an issue with ldiff not working because actions were changed from
symbols to strings.
== 1.0.1 / -
* Minor modifications to the gemspec, the README.
* Renamed the diff program to ldiff (as well as the companion batch file) so as
to not collide with the standard diff program.
* Fixed issues with RubyGems. Requires RubyGems > 0.6.1 or >= 0.6.1 with the
latest CVS version.
== 1.0 / -
* Initial release based mostly on Perl's Algorithm::Diff.
