ID: 12944 Title: REST API: acquire wato configuration lock before changing files Component: Core & setup Level: 1 Class: Bug fix Version: 2.0.0p6 Previously, the REST API failed to acquire the WATO configuration lock before performing file system operations. This could lead to race conditions when performing actions in parallell. This Werk introduces this lock for all endpoints that do change configuration files. No further action is needed.
