[//]: # (werk v2) # REST-API: Introduce include_links and include_extensions to list endpoints key | value ---------- | --- date | 2024-09-03T13:25:46+00:00 version | 2.4.0b1 class | feature edition | cre component | rest-api level | 1 compatible | yes This Werk introduces two flags to most list endpoints. The first flag `include_links` was already present for list host configs. It controls whether the links of the individual values should be included. This flag is enabled by default. The second flag `include_extensions` toggles the inclusion of the extensions, which contain most of the attributes. This flag is also enabled by default. Both of these flags give users options to improve performance and reduce response sizes.
