+skiboot-5.3.3
+-------------
+
+skiboot-5.3.3 was released on Friday September 2nd, 2016.
+
+This is the 4th stable release of skiboot 5.3, the new stable release of
+skiboot (first released with 5.3.0 on August 2nd, 2016).
+
+Skiboot 5.3.3 replaces skiboot-5.3.2 as the current stable version. It contains
+two bug fixes for machines utilizing the NPU (i.e. Garrison)
+
+Over skiboot-5.3.2, the following fixes are included:
+
+- hw/npu: assert the NPU irq min is aligned.
+- hw/npu: program NPU BUID reg properly
+ The NPU BUID register was incorrectly programmed resulting in npu
+ interrupt level 0 causing a PB_CENT_CRESP_ADDR_ERROR checkstop,
+ and irqs from npus in odd chips being aliased to and processed
+ as the interrupts from the corresponding npu on the even chips.
