Checkmk Werk 12947: REST API: ETag validation is not less strict

ID: 12947 Title: REST API: ETag validation is not less strict Component: Core & setup Level: 1 Class: Bug fix Version: 2.1.0i1 Previously the ETag/If-Match header pair were required to have a hexadecimal pattern of 32 bytes length. This was not honored by some endpoints, resulting in bad requests that should have been OK. This restriction has now been lifted and ETags can have any string content. There is no furhter action necessary.
