 # Hypha Change Log
 
+### 0.20.38
+ - Allow passing workspace and expires_in to the `login` function to generate workspace specific token.
+ - When using http endpoint to access the service, you can now pass workspace specific token to the http header `Authorization` to access the service. (Previously, all the services are assumed to be accessed from the same service provider workspace)
+
+### 0.20.37
+ - Add s3-proxy to allow accessing s3 presigned url in case the s3 server is not directly accessible. Use `--enable-s3-proxy` to enable the s3 proxy when starting Hypha.
+ - Add `artifact-manager` service to provide comprehensive artifact management, used for creating gallery-like service portal. The artifact manager service is backed by s3 storage and supports presigned url for direct access to the artifacts. This is a replacement of the previous `card` service.
+
 ### 0.20.36
 
  - Upgrade hypha-rpc to support updating reconnection token (otherwise it generate token expired error after some time)

 ### User Login and Token-Based Authentication
 
-To access the full features of the Hypha server, users need to log in and obtain a token for authentication. The new `login()` function provides a convenient way to display a login URL, once the user click it and login, it can then return the token for connecting to the server.

+#### Additional Arguments for Login
+
+You can specify the `workspace` and `expires_in` arguments in the `login()` function so that the token is generated for a specific workspace and expires after a certain period of time.
+
+```python
+token = await login(
+    {
+        "server_url": SERVER_URL,
+        "workspace": "my-workspace",
+        "expires_in": 3600,
+    }
+)
+```
+
+If a token is generated for a specific workspace, when calling `connect_to_server`, you need to specify the same workspace as well:

+server = await connect_to_server({"server_url": "https://ai.imjoy.io", "token": token, "workspace": "my-workspace"})
