+security enhancements: use separate DIDs for signing, encryption, verification of web5 connect
+feature enhancements: prepare code for the option of exporting the DWA's DID to a wallet
+
+breaking changes for wallet authors.
+
+web5 connect's `getAuthRequest()` now returns an object which include both the authRequest and a DID:
+
+```ts
+{
+  authRequest: Web5ConnectAuthRequest;
+  clientEcdhDid: DidResolutionResult;
+}
+```
+
+web5 connect's `submitAuthResponse()` now requires that the did received from `getAuthRequest()` is passed in to the method at position 4:
+
+```ts
+async function submitAuthResponse(
+  selectedDid: string,
+  authRequest: Web5ConnectAuthRequest,
+  randomPin: string,
+  clientEcdhDid: DidResolutionResult,
+  agent: Web5Agent
+) { ... }
+```
