+* SDK Hosting Improvements
+* Terminator validation utility
+
+## SDK Hosting Improvments
+
+In previous versions of OpenZiti, if many SDK clients were attempting to establish hosting, the controller could get overwhelmed. 
+In this release, routers will use the rate limiter pool introduced in 0.27.6 when creating terminators on behalf of sdk clients
+hosting applications. Additionally, routers now have the ability to verify terminator state with the sdk, if the sdk supports it.
+In general, hosting large numbers of services using the sdk should now be less suceptible to thundering herd issues.
+
+## Manual Terminator Validation
+
+There is a new CLI command available to validate terminator state. This is primarily a developer tool to validate that terminator 
+setup logic is correct. However it may also be used to diagnose and resolve issues with production systems, should the need arise.
