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 1.4.3, providing a simple extension that allows for Diff::LCS::Change objects to be treated implicitly as arrays and fixes a number of formatting issues. Ruby versions below 2.5 are soft-deprecated, which 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. The next major release will completely break compatibility.

The mime-types library provides a library and registry for information about MIME content type definitions. It can be used to determine defined filename extensions for MIME types, or to use filename extensions to look up the likely MIME type definitions. Version 3.0 is a major release that requires Ruby 2.0 compatibility and removes deprecated functions. The columnar registry format introduced in 2.6 has been made the primary format; the registry data has been extracted from this library and put into {mime-types-data}[https://github.com/mime-types/mime-types-data]. Additionally, mime-types is now licensed exclusively under the MIT licence and there is a code of conduct in effect. There are a number of other smaller changes described in the History file.

mime-types-data provides a registry for information about MIME media type definitions. It can be used with the Ruby mime-types library or other software to determine defined filename extensions for MIME types, or to use filename extensions to look up the likely MIME type definitions.

Text::Hyphen is a Ruby library to hyphenate words in various languages using Ruby-fied versions of TeX hyphenation patterns. It will properly hyphenate various words according to the rules of the language the word is written in. The algorithm is based on that of the TeX typesetting system by Donald E. Knuth. This is originally based on the Perl implementation of [TeX::Hyphen][] and the [Ruby port][]. The language hyphenation pattern files are based on the sources available from [CTAN][] as of 2004.12.19 and have been manually translated by Austin Ziegler. This is a small feature release adding Russian language support and fixing a bug in the custom hyphen support introduced last version. This release provides both Ruby 1.8.7 and Ruby 1.9.2 support (but please read below). In short, Ruby 1.8 support is deprecated and I will not be providing any bug fixes related to Ruby 1.8. New features will be developed and tested against Ruby 1.9 only.

{Marlowe}[https://github.com/KineticCafe/marlowe] is a Rack middleware that extracts or creates a request ID using a pre-defined header, permitting request correlation across multiple services. When using Rails, Marlowe automatically adds itself to the middleware before <tt>Rails::Rack::Logger</tt>. As of Marlowe 3.0, a Faraday middleware is provided (<tt>require 'marlowe/faraday'</tt>).

AppIdentity is a Ruby implementation of the Kinetic Commerce application identity proof algorithm as described in its [spec][].

This release is the *last* version of cartage-rack. It will be replaced with a different tool in the future, but this release will allow installation in modern Ruby versions. cartage-rack is a plug-in for {cartage}[https://github.com/KineticCafe/cartage] to provide a Rack application that reports on release metadata. Cartage provides a repeatable means to create a package for a Rails application that can be used in deployment with a configuration tool like Ansible, Chef, Puppet, or Salt. The package is created with its dependencies bundled in +vendor/bundle+, so it can be deployed in environments with strict access control rules and without requiring development tool access.
