+### Breaking Changes
+
+Build, CI/CD:
+
+* Remove `flatdict` dependency as it breaks builds on newer targets (RHEL 10, SLE 15/16) and no fix is available that also supports older targets (such as RHEL 8). This has the consequence that the [statuspal plugin](check-plugins/statuspal) is currently broken until the affected code is rewritten.
