 Upgrading Slack-Ruby-Bot-Server
 ===============================
 
+### Upgrading to >= 1.2.0
+
+#### New Team Fields
+
+The following fields have been added to `Team`.
+
+* `oauth_scope`: Slack OAuth scope
+* `oauth_version`: Slack OAuth version used
+
+No action is required for Mongoid.
+
+If you're using ActiveRecord, create a migration to add these fields.
+
+```ruby
+class AddOauthFields < ActiveRecord::Migration[5.0]
+  def change
+    add_column :teams, :oauth_scope, :string
+    add_column :teams, :oauth_version, :string, default: 'v1', null: false
+  end
+end
+```
+
 ### Upgrading to >= 1.1.0
 
 #### Extracted RealTime (Legacy) Support
 
 New slack apps may no longer access RTM. Classic Slack apps can no longer be submitted to the app directory as of December 4th, 2020. In preparation for these changes slack-ruby-bot-server no longer includes RTM components by default. These have been extracted to a new gem [slack-ruby-bot-server-rtm](https://github.com/slack-ruby/slack-ruby-bot-server-rtm).
