[//]: # (werk v2) # notification rules: match host tags can't contain duplicate tag ids or duplicate tag group ids key | value ---------- | --- date | 2024-07-29T07:49:29+00:00 version | 2.3.0p12 class | fix edition | cre component | rest-api level | 1 compatible | no When creating/updating a notification rule via the REST-API, it was previously possible to set duplicate tag groups or duplicate tag ids for the 'match_host_tags' field. To be consistent with the UI behaviour , we no longer allow this. With this werk, we have made this change.
