Dear community!
From version 2.1.0p15 the usual Checkmk HASH file will be split.
If you have a certain system set up that is checking the hashes automatically, please be sure to make changes before updating: this is not a breaking change but to avoid any disruptions in your processes, it is better to be assured your setup is prepared for the change.
Here is the werk introducing the change
Please note that this change will also affect version 2.0.0p30.
Let us know if you have any questions,
Sara and the Checkmk Development Team
