+==============
+
+skiboot 6.0.16 was released on Tuesday February 5th, 2019. It replaces
+:ref:`skiboot-6.0.15` as the current stable release in the 6.0.x series.
+
+It is recommended that 6.0.16 be used instead of any previous 6.0.x version
+due to the bug fixes it contains.
+
+Bug fixes included in this release are:
+
+- p9dsu: Fix p9dsu default variant
+
+  Add the default when no riser_id is returned from the ipmi query.
+
+  This addresses: https://github.com/open-power/boston-openpower/issues/1369
+
+  Allow a little more time for BMC reply and cleanup some label strings.
+
+- p9dsu: Fix p9dsu slot tables
+
+  Set the attributes on the slot tables to account for
+  builtin or pluggable etypes, this will allow pci
+  enumeration to calculate subordinate buses.
+
+  Update some slot label strings.
+
+  Add WIO Slot5 which is standard on the ESS config.
+
+- phb4: Generate checkstop on AIB ECC corr/uncorr for DD2.0 parts
+
+  On DD2.0 parts, PCIe ECC protection is not warranted in the response
+  data path. Thus, for these parts, we need to flag any ECC errors
+  detected from the adjacent AIB RX Data path so the part can be
+  replaced.
+
+  This patch configures the FIRs so that we escalate these AIB ECC
+  errors to a checkstop so the parts can be replaced.
+
+- core/lock: Stop drop_my_locks() from always causing abort
+
+  Fix an erroneous failure in an error path that looked like this: ::
+
+      LOCK ERROR: Releasing lock we don't hold depth @0x30493d20 (state: 0x0000000000000001)
+      [13836.000173140,0] Aborting!
+      CPU 0000 Backtrace:
