 This document summarizes changes between MOA ZS Releases that were made in the MOA ZS codebase and in the app2mzs interfaces.
 For a non-normative summary of changes that were made in the ZUSE specifications (and therefore affect MOA ZS directly and a sender application indirectly), the reader is referred to [ZUSE Specification Changelog](zusespec-changelog.md).
 
+## Changes MOA ZS 2.0.0 RC8
+
+- Fix: Improve exception handling on MOA ZS: Process exception
+  correctly after backend service times out. Before: When the MOA ZS
+  backend service times out while processing a delivery request, MOA
+  ZS answers synchronously to the Sender app and forwards the result
+  asynchronously at a later point. If an exception were to occur after
+  the timeout, MOA ZS would swallow this exception without being
+  properly processed. The fix: If an exception occurs, MOA ZS converts
+  the exception into a response and hands it over to the sink hub for
+  proper processing of the event.
+- Fix: Parser Error that occurs when MOA ZS mzs backend service times out.
