+Release notes for Gerrit 2.4.2
+==============================
+
+Gerrit 2.4.2 is now available:
+
+link:http://code.google.com/p/gerrit/downloads/detail?name=gerrit-2.4.2.war[http://code.google.com/p/gerrit/downloads/detail?name=gerrit-2.4.2.war]
+
+There are no schema changes from 2.4, or 2.4.1.
+
+However, if upgrading from anything earlier, follow the upgrade
+procedure in the 2.4 link:ReleaseNotes-2.4.html[ReleaseNotes].
+
+Security Fixes
+--------------
+* Some access control sections may be ignored
++
+Gerrit sometimes ignored an access control section in a project
+if the exact same section name appeared in All-Projects. The bug
+required an unrelated project to have access.inheritFrom set to
+All-Projects and be accessed before the project that has the same
+section name as All-Projects. This is an unlikely scenario for
+most servers, as Gerrit does not normally set inheritFrom equal to
+All-Projects. The usual behavior is to not supply this property in
+project.config, and permit the implicit inheritence to take place.
