 ### Breaking changes
 
-Several breaking changes are introduced. You will have to slightly change your configuration file and a migration script will take care of updating your database cluster. Please follow the instructions in [UPDATE.md](/UPDATE.md#update-to-kong-050) for an update without downtime.
+Several breaking changes are introduced. You will have to slightly change your configuration file and a migration script will take care of updating your database cluster. **Please follow the instructions in [UPDATE.md](/UPDATE.md#update-to-kong-050) for an update without downtime**.
 
 - Many plugins were renamed due to new naming conventions for consistency. [#480](https://github.com/Mashape/kong/issues/480)
+- In the configuration file, the Cassandra `hosts` property was renamed to `contact_points`. [#513](https://github.com/Mashape/kong/issues/513)
 - `public_dns` and `target_url` properties of APIs were respectively renamed to `inbound_dns` and `upstream_url`. [#513](https://github.com/Mashape/kong/issues/513)
 - `plugins_configurations` have been renamed to `plugins`, and their `value` property has been renamed to `config` to avoid confusions. [#513](https://github.com/Mashape/kong/issues/513)
 - The database schema has been updated to handle the separation of plugins outside of the core repository.
