+Removes support for non-cdc subscriptions. This means the only available engine for subscriptions is `Neo4jGraphQLSubscriptionsCDCEngine`:
+
+```ts
+new Neo4jGraphQL({
+    typeDefs,
+    driver,
+    features: {
+        subscriptions: new Neo4jGraphQLSubscriptionsCDCEngine({
+            driver,
+        }),
+    },
+});
+```
+
+The default behaviour of subscriptions has also been updated to use CDC, so now passing `true` will use the CDC engine with the default parameters and driver:
+
+```ts
+new Neo4jGraphQL({
+    typeDefs,
+    driver,
+    features: {
+        subscriptions: true,
+    },
+});
+```
