 This document describes the upgrade instructions from `3.7.1` to `3.8.0`.
 
+## Configuration changes
+
+### docker-compose changes
+There are a few changes to our `docker-compose.yml` file for the `aerie_action` and `aerie_workspace` services. If you maintain your own docker-compose file, you'll need to make these changes:
+
+* Under the `aerie_action` container, in the `environment` section, add `HASURA_GRAPHQL_JWT_SECRET: "${HASURA_GRAPHQL_JWT_SECRET}"`
+* Under the `aerie_action` container, in the `environment` section, you can remove the `HASURA_GRAPHQL_ADMIN_SECRET` variable as it is no longer needed
+* Under the `aerie_workspace` container, add `HASURA_GRAPHQL_URL: http://hasura:8080/v1/graphql` (or your equivalent, if running on a different url/port)
+
+See this file in the `aerie` repo for a full example: https://github.com/NASA-AMMOS/aerie/blob/develop/deployment/docker-compose.yml
+
+### Hasura metadata yaml file changes
+
+If you maintain your own versions of Hasura metadata files for granular control of permissions (rare), you may need to update them to contain the latest values for Workspaces. [This PR is a good reference](https://github.com/NASA-AMMOS/aerie/pull/1757/files#diff-def18dd27c7d2c9dfe61a27ba55973f94e8354160d817a99c7ef0ad4c0682e7a) demonstrating the changes to the `yaml` files in `deployment/hasura/metadata`
+
+
+# DB Migrations
+
+A DB migration was added in this release to support workspace permissions.. If you are upgrading from a past version and want to preserve your data, follow the instructions in the
+[Database Migrations Guide](../deployment/advanced-database-migrations.mdx) to apply migrations after upgrading. Make sure you are using the latest version of the migration script from the `Deployment.zip`.
+
 ## Sequence Adaptation interface changes
 
 This release contains breaking changes to our Sequence Adaptation interface. Most significantly, compiled adaptations are now expected to be *CommonJS modules*, which start with external `require(...)` statements for any CodeMirror dependencies, and end with `exports.adaptation = ...`.
