 ## What's New
 
 * Auth Rate Limiter
+* Link Management Fixes
 * ziti edge quickstart command deprecates redundant --already-initialized flag. The identical behavior is implied by --home.
 
 ## Backwards compatibility
@@ -11,6 +12,9 @@ This release includes new response types from the REST authentication APIS. They
 `429` (server too busy) responses to auth requests. As this is an API change, the version number is 
 being bumped to 0.32.
 
+If controller and router are both v0.32 or later, only the router which dialed a link will report it to the controller. 
+If the controller is older, newer routers will report links from both the dialing and listening side of the link.

 ## Auth Rate Limiter
 
 In order to prevent clients from overwhelming the server with auth requests, an auth rate limiter has been introduced.
@@ -37,15 +41,46 @@ New metrics:
 * `auth.limiter.window_size`  - current size at which new auth attempts will be rejected
 * `auth.limiter.work_timer`   - tracks the rate at which api sessions are being created and how long it's taking to create them
 
+## Link Management Fixes
+
+With long lived link ids, there was potential for link control message to be ambiguous, as the link id wasn't enough to identify
+a specific iteration of that link. An iteration field has been added to links so that messaging is unambiguous. 
+Links will also only be reported from the dialing router now to reduce ambiguouity and race condition in link control channel
+messaging.
+
+## Router SSL Handshake Timeout Config
+
+There is a new router config setting which allows setting the SSL handshake timeout for TLS connections, when using ALPN for listeners.
+
+```
+tls:
+  handshakeTimeout: 15s
+```
