+Feature 75 "Make index name configurable"
+==========================================
+
+Prior to the change the index name was not changeable and hardcoded to `typo3content`.
+Now you can change the index name for different use cases.
+
+You can now use one Elasticsearch server for multiple TYPO3 installations or multiple environments.
+
+The default is set to `typo3content`. No changes are necessary.
+
+See :issue:`75`.
