+# Release 2.4.2 (Night of the Living Dead)
+
+Released on 2022-04-24
+
+Bitrot, futureproofing, and bug fix release.
+
+### Compatibility ###
+
+No migration is required when upgrading from RethinkDB 2.4.x. Please read the
+[RethinkDB 2.4.0 release notes][release-notes-2.4.0] if you're upgrading from
+an older version.
+
+[release-notes-2.4.0]: https://github.com/rethinkdb/rethinkdb/releases/tag/v2.4.0
+
+RethinkDB 2.4.x servers cannot be mixed with servers running RethinkDB
+2.3.x or earlier in the same cluster.
+
+### API-breaking changes ###
+
+The `r.js` ReQL command now uses QuickJS to run instead of v8.
+Because RethinkDB's v8 version was old, this will allow you to use
+newer JavaScript features.  However, performance and the results of
+your JavaScript code may differ.
+
+### Substantive Changes ###
+
+(Issue numbers point into the https://github.com/rethinkdb/rethinkdb
+bugtracker.  For a completionist list of changes, run `git log
+v2.4.1..v2.4.2`.)
