+# KAZOO master (5.x) is closed at the moment
+
+Development of KAZOO 5.x is currently closed to public commits as we prepare the infrastructure necessary for the app exchange. Once the infrastructure is ready, all developers - 2600Hz, partners, and open source community - will benefit from having the same build systems available, as well as a release channel from which folks can purchase those apps for use on any KAZOO cluster.
+
+Thanks for your patience! We're excited to show 5.0 off!
