+
+* 2022-03-08 Markus FRANK ([PR#894](https://github.com/AIDASoft/DD4hep/pull/894))
+  - The refactoring of namespaces (some years ago) left some factory name discrepancies in DDEve.
+  This PR fixes them and re-enables the various views and projections.
+  See issue https://github.com/AIDASoft/DD4hep/issues/893.
+  - There are still some issues when loading a new file, which are not yet entirely understood.
+  The suspicion is that the displayed 2D histograms somehow "reside" in the opened file and disappear
+  when the file is closed. This however needs confirmation (and eventually fixing).
