 Pending changes in the mainline
 ===============================
 
-General
--------
-* Orthanc Explorer : when performing a Query/Retrieve operation, the tag
-  default values are now set to an empty string instead of '*', which allows
-  to match even if the tag is not present. This allows malformed DICOM files
-  to be matched, even though they lack required tags such as `PatientSex`
