[//]: # (werk v2) # swagger: fix JSON query parameters key | value ---------- | --- date | 2024-06-04T06:29:07+00:00 version | 2.3.0p5 class | fix edition | cre component | rest-api level | 1 compatible | yes Some query parameters (like livestatus queries) are supposed to be JSON encoded. Previously, swagger (the interactive REST API GUI) would encode these queries differently, leading to unexpected errors. Our OpenAPI spec was updated to fix this issue. Other clients are not affected, unless they were generated using our OpenAPI spec.
