## 1.3 / 2017-01-18
* Bugs fixed:
* Fixed an error for bin/ldiff --version. Fixes [issue #21][].
* Force Diff::LCS::Change and Diff::LCS::ContextChange to only perform
equality comparisons against themselves. Provided by Kevin Mook in
[pull request #29][].
* Fix tab expansion in htmldiff, provided by Mark Friedgan in
[pull request #25][].
* Silence Ruby 2.4 Fixnum deprecation warnings. Fixxues [issue #38][] and
[pull request#36][].
* Ensure that test dependencies are loaded properly. Fixes [issue #33][]
and [pull request #34][].
* Fix [issue #1][] with incorrect intuition of patch direction. Tentative
fix, but the previous failure cases pass now.
* Tooling changes:
* Added SimpleCov and Coveralls support.
* Change the homepage (temporarily) to the GitHub repo.
* Updated testing and gem infrastructure.
* Modernized the specs.
* Cleaned up documentation.
* Added a Code of Conduct.
## 1.2.5 / 2013-11-08
* Bugs fixed:
* Comparing arrays flattened them too far, especially with
Diff::LCS.sdiff. Fixed by Josh Bronson in [pull request #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!
* 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!
* 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.
* 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.
## 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 found this in
[rspec/rspec-expectations#219][] and provided a first pass
implementation in [pull request #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).
* Adding Travis CI testing for Ruby 2.0.
## 1.2.1 / 2013-02-09
* Bugs Fixed:
* As seen in [rspec/rspec-expectations#200][], the release of
Diff::LCS 1.2 introduced an unnecessary public API change to
Diff::LCS::Hunk (see the change at
[rspec/rspec-expectations@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.
* Resolved [issue #2][] by handling `string[string.size, 1]` properly (it
returns `""` not `nil`).
* Michael Granger (ged) fixed an implementation error in
Diff::LCS::Change and added specs in [pull request #8][]. Thanks!
* Made the code auto-testable.
* Vít Ondruch (voxik) provided the latest version of the GPL2 license
file in [pull request #10][]. Thanks!
* 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!
* Code Style Changes:
* Removed trailing spaces.
* Calling class methods using `.` instead of `::`.
* Vít Ondruch (voxik) removed unnecessary shebangs in [pull request #9][].
Thanks!
* Kenichi Kamiya (kachick) removed some warnings of an unused variable in
lucky [pull request #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][].
* Eliminated Ruby warnings. Resolves [issue #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 (Set returned from patch command does not contain last equal
part).
* 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.
