+- Update to new upstream release 4.1.1
+* This release implements support for ZBC and ZAC revision 4 and
+  above draft standards.
+* Fixed the fake backend driver to pass all tests even if the
+  device specified is very small (i.e. it has only a few sequential
+  zones).
+* Display SG_IO ioctl error message only when the log level is set
+  to debug/verbose.
