diff-lcs 1.3

- Updated testing and gem infrastructure.
- Cleaning up documentation.
- Modernizing specs.
- Silence Ruby 2.4 Fixnum deprecation warnings. Fixes #36, #38.
- Ensure test dependencies are loaded. Fixes #33, #34 so that specs can be run
  independently.
- Fix issue #1 with incorrect intuition of patch direction. Tentative fix, but
  the failure cases pass now.

+
+## 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.
