+# Release Notes - v0.11.0
+
+This release contains several notable features on the User Interface and on
+the Helm Chart, in addition to prefix support when listing objects and an
+updated version of the radosgw we use for the backend.
+
+This release is meant for testing and feedback gathering. Is is not
+recommended for production use.
+
+Should a bug be found and not expected to be related to the list below, one
+should feel encouraged to file an issue in our
+[GitHub repository](https://github.com/aquarist-labs/s3gw/issues/new/choose).
+
+## Features
+
+- UI:
+  - Add tags support for buckets (gh#aquarist-labs/s3gw#285).
+  - Add notification sidebar (gh#aquarist-labs/s3gw#172).
+  - Add option to remove buckets objects before deleting a bucket in the
+    administrator view.
+
+- Charts:
+  - Configuration options: `useExistingSecret` and
+    `defaultUserCredentialsSecret`.
+
+    These fields allow the user to specify an existing secret containing
+    the S3 credentials for the default user.
+  - `useExistingSecret` is a boolean field defaulted to false.
+  - `defaultUserCredentialsSecret` is a string field denoting a `secret` in
+    the `s3gw` namespace. It must contain 2 keys:
+    - `RGW_DEFAULT_USER_ACCESS_KEY` that is the S3 Access Key for the default
+      user.
+    - `RGW_DEFAULT_USER_SECRET_KEY` that is the S3 Secret Key for the default
+      user.
+  - When `useExistingSecret` is set to `false`, the chart will create
+    the secret using values from the preexisting fields `accessKey` and
+    `secretKey`.
+  - Setting `accessKey` or `secretKey` as the empty string, will force the
+    Chart to compute random alphanumeric values for the fields.
+  - Defaulted values:
+    - `useExistingSecret`: false
+    - `defaultUserCredentialsSecret`: s3gw-creds
+
+- SFS/Backend:
+  - Added prefix support when listing objects and object versions.
+
