+skiboot 6.0.13 was released on Wednesday November 14th, 2018. It replaces
+:ref:`skiboot-6.0.12` as the current stable release in the 6.0.x series.
+
+This release includes one pflash change. This release does not modify skiboot
+itself, so there is no reason to upgrade to this version if you're on 6.0.12
+already. This release is made exclusively so OpenBMC can ship an updated pflash
+from a tagged release.
+
+The pflash change is:
+
+- pflash: Add --skip option for reading
+
+  Add a --skip=N option to pflash to skip N number of bytes when reading.
+  This would allow users to print the VERSION partition without the STB
+  header by specifying the --skip=4096 argument, and it's a more generic
+  solution rather than making pflash depend on secure/trusted boot code.
