+## Changes
+
+- Weaver: add option to automatically unregister old providers
+
+  Introduces the `WEAVER_UNREGISTER_DROPPED_PROVIDERS` variable. If set to "True", Weaver providers that are no longer 
+  working (not responding when deployed) and are not named in `WEAVER_WPS_PROVIDERS` will be unregistered. This is  
+  useful when deploying Weaver with fewer providers than a previous deployment.
+
+  For example, if the stack is deployed with the Weaver, Finch, and Raven components. Then later deployed with just
+  Weaver and Raven, the Finch provider will be unregistered from weaver.
+
+  Previously, the Finch provider would have remained as a Weaver provider despite the fact that it has been removed from
+  the stack.
