+### API Changes for Traffic Prices and Server Type Included Traffic
+
+There will be a breaking change in the API regarding Traffic Prices and Server Type Included Traffic on 2024-08-05. This release implements the necessary changes for the CLI.
+
+Until now, the `hcloud server-type list` command had a column `traffic`. This is no longer possible, because there is no single included traffic for a server type, and instead this depends on the location. We have set the field to `-` and removed it from the default columns. The information is still available in `hcloud server-type describe <server-type-name>`, now in the "Pricing" section of the output.
+
+This also affects the JSON and YAML output of both `hcloud server-type list` and `hcloud server-type describe` as we use the API schema for this.
+
+You can learn more about this change in [our changelog](https://docs.hetzner.cloud/changelog#2024-07-25-cloud-api-returns-traffic-information-in-different-format).
