+* Applications may now specify client and server entry point modules in a
+  newly-supported `"meteor"` section of `package.json`:
+  ```js
+  "meteor": {
+    "mainModule": {
+      "client": "client/main.js",
+      "server": "server/main.js"
+    }
+  }
+  ```
+  When specified, these entry points override Meteor's default module
+  loading semantics, rendering `imports` directories unnecessary. If
+  `mainModule` is left unspecified for either client or server, the
+  default rules will apply for that architecture, as before.
