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 1.4, providing a simple extension that allows for Diff::LCS::Change objects to be treated implicitly as arrays. Ruby versions below 2.5 are soft-deprecated. This means that older versions are no longer part of the CI test suite. If any changes have been introduced that break those versions, bug reports and patches will be accepted, but it will be up to the reporter to verify any fixes prior to release. A future release will completely break compatibility.
