+- Baptiste Courtois (@annih) has done significant work on making `bin/ldiff`
+  work better, contributing a number of issues and pull requests. These include:
+
+  - Separation of command parsing from diff-generation in `Diff::LCS::Ldiff`
+    code extraction making it easier to use separately from the `bin/ldiff`
+    command in [#103][pull-103]. This partially resolves [#46][issue-46].
+
+  - Improvement of binary and empty file detection and tests in [#104][pull-104]
+    and [#105][pull-105]. This resolves issues [#100][issue-100],
+    [#102][issue-102].
+
+  - Various ldiff fixes for output [#101][pull-101] resolves issues
+    [#106][issue-106] (ldiff ed scripts are inverted), [#107][issue-107] (ldiff
+    hunk ranges are incorrect; regression or incorrect fix for [#60][issue-60]),
+    and [#95][issue-95].
 
 - Patrick Linnane fixed various minor typos. [#93][pull-93]
 
 - Mark Young added a Changelog link to the RubyGems metadata. [#92][pull-92]
   This has been modified to incorporate it into the README.
 
+- Updated the documentation on `Diff::LCS#lcs` to be clearer about the
+  requirements for object equality comparison. This resolves [#70][issue-70].

     That is, `LCS(s2, s1)` should produce a sequence that is transitive with
