This page is very out of date. This commit probably doesn't
cover everything there is to say about stability and compatability
in cephadm, but it at least gets it noticeably closer to reality

-Cephadm is under development. Some functionality is incomplete. Be aware
-that some of the components of Ceph may not work perfectly with cephadm.
-These include:
-
-- RGW
+Cephadm is relatively stable nowadays, but new functionality is still being
+added and bugs are occasionally discovered. If any issues are found, please
+open a tracker issue under the orchestrator component (https://tracker.ceph.com/projects/orchestrator/issues)
 
 Cephadm support remains under development for the following features:
 
-- Ingress
-- Cephadm exporter daemon
-- cephfs-mirror
+- ceph-exporter deployment
+- stretch mode integration
+- monitoring stack (moving towards prometheus service discover and providing TLS)
+- RGW multisite deployment support (requires lots of manual steps currently)
+- cephadm agent
 
 If a cephadm command fails or a service stops running properly, see
