+=============
+
+skiboot 5.9.9 was released on Monday May 28th, 2018. It replaces
+:ref:`skiboot-5.9.8` as the current stable release in the 5.9.x series.
+
+Over :ref:`skiboot-5.9.8`, we have two bug fixes and a build fix, they are:
+
+- OPAL_PCI_SET_POWER_STATE: fix locking in error paths
+
+  Otherwise we could exit OPAL holding locks, potentially leading
+  to all sorts of problems later on.
+- lpc: Clear pending IRQs at boot
+
+  When we come in from hostboot the LPC master has the bus reset indicator
+  set. This error isn't handled until the host kernel unmasks interrupts,
+  at which point we get the following suprious error: ::
+
+    [   20.053560375,3] LPC: Got LPC reset on chip 0x0 !
+    [   20.053564560,3] LPC[000]: Unknown LPC error Error address reg: 0x00000000
+
+  Fix this by clearing the various error bits in the LPC status register
+  before we initalise the skiboot LPC bus driver.
+- stb: Build fixes in constructing secure and trusted boot header
