+- Update to new upstream release 5.5.0
+  * Fixed various problems with the fake backend driver
+    (emulation mode), in particular when using a 4K sector disk
+    as backend storage.
+  * Properly set up direct I/O operation with the SG_IO interface
+    (SCSI and ATA backend drivers).
+  * Properly handle the maximum and optimal number of open zones
+    for drives with no limit and drives not reporting any limit.
+  * Skip open zone resource tests for drives with no limit or an
+    unreported limit on the maximum/optimal number of open zones.
+  * Add a new test to verify that a drive returns the correct
+    ASC/ASCQ sense error codes when writing to a full zone (HM
+    drives only).
