+
+Ruby 4.0.2 has been released.
+
+This is a routine update that includes a bugfix in YJIT for [NoMethodError on Puma](https://github.com/puma/puma/issues/3620).
+Please see the [GitHub Releases](https://github.com/ruby/ruby/releases/tag/v4.0.2) for further details.
+
+## Release Schedule
+
+We intend to release the latest stable Ruby version (currently Ruby 4.0) every two months following the most recent release.
+Ruby 4.0.3 will be released in May, 4.0.4 in July, 4.0.5 in September, and 4.0.6 in November.
+
+If a change arises that significantly affects users, a release may occur earlier than planned, and the subsequent schedule may shift accordingly.
