+#### version_update_mask
+(*string*) This field requires a Python regex pattern. It's used with `re.match`.
+ The old version contained in the *dist-git target branch specfile* and the *newly released version in upstream* 
+ have both to match this reg exp and the matching value has to be the same otherwise Packit will not sync the 
+ release downstream.
+ As an example a  `version_update_mask`: `\d+\.\d+\.`, a dist-git branch *f39* specfile *version*: *3.8.0* and 
+ a new upstream *release tag*: *3.9.0* are matching but the value is not the same and thus a *3.9.0* release 
+ will not land automatically in *f39*.
+
+#### version_update_mask_targets
+(*list of strings*) Names of the dist-git branches where the `version_update_mask` check should be run.
+If `version_update_mask_targets` key is not set but `version_update_mask` is, then the check will be
+executed in all *fedora-branched* branches.
