 # master
 
+# 3.1.0
+
+This brings the Relay version to `18.2.0`.
+
+If you have enabled the feature flags in `relay.config.js` for aliased fragments or Relay resolvers you'll need to remove them from the config file as they are now on by default, and not removing them will cause the compiler to fail with a non super helpful error message.
+
+- **Upgrade versions**: `react-relay` and `relay-runtime` to `18.2.0`.
+- Add support for `Fragment.waitForFragmentData`, a new API in Relay 18.2 that lets you wait for fragment data outside of React.
+- Experimental: Add a "non React" mode to the PPX, which makes sure only APIs that don't rely on React directly are exposed. This is intended to be a way to simplify using RescriptRelay without React. Activate by passing `-non-react` to the PPX, like `"ppx-flags": [["rescript-relay/ppx", "-non-react"]]`.
+
 # 3.0.1
 
 - Add `Environment.findAllConnectionIds` for finding all IDs of all connection instances for a specific connection, regardless of what configs that connection has been fetched (and cached) with.
