Subject: [ANN] diff-lcs 1.2.3 Released

diff-lcs version 1.2.3 has been released!

* home: <http://diff-lcs.rubyforge.org/>
* code: <https://github.com/halostatue/diff-lcs>
* bugs: <https://github.com/halostatue/diff-lcs/issues>
* rdoc: <http://rubydoc.info/github/halostatue/diff-lcs>

Diff::LCS computes the difference between two Enumerable sequences using the
McIlroy-Hunt longest common subsequence (LCS) algorithm. It includes utilities
to create a simple HTML diff output format and a standard diff-like tool.

This is release 1.2.3, fixing a bug in value comparison where the left side of
the comparison was the empty set, preventing the detection of encoding. Thanks
to Jon Rowe for fixing this issue. This is a strongly recommended release.

*Note*: There is a known issue with Rubinius in 1.9 mode reported in
{rubinius/rubinius#2268}[https://github.com/rubinius/rubinius/issues/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.

Changes:

## 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.
