+skiboot-5.3.4
+-------------
+
+skiboot-5.3.4 was released on Tuesday September 13th, 2016.
+
+This is the 5th stable release of skiboot 5.3, the new stable release of
+skiboot (first released with 5.3.0 on August 2nd, 2016).
+
+Skiboot 5.3.4 replaces skiboot-5.3.3 as the current stable version. It contains
+a couple of bug fixes, specifically around failing XSCOMs.
+
+Over skiboot-5.3.3, the following fixes are included:
+
+- xscom: Initialize the data to a known value in xscom_read
+  In case of error, don't leave the data random. It helps debugging when
+  the user fails to check the error code. This happens due to a bug in the
+  PRD wrapper app.
+- xscom: Map all HMER status codes to OPAL errors
+- centaur: Mark centaur offline after 10 consecutive access errors
+  This avoids spamming the logs when the centaur is dead and PRD
+  constantly tries to access it
+- nvlink: Fix bad PE number check in error inject code path (<= rather than <)
