+
+skiboot 6.0.15 was released on Monday December 17th, 2018. It replaces
+:ref:`skiboot-6.0.14` as the current stable release in the 6.0.x series.
+
+It is recommended that 6.0.15 be used instead of any previous 6.0.x version
+due to the bug fixes it contains.
+
+Bug fixes included in this release are:
+
+- i2c: Fix i2c request hang during opal init if timers are not checked
+
+  If an i2c request cannot go through the first time, because the bus is
+  found in error and need a reset or it's locked by the OCC for example,
+  the underlying i2c implementation is using timers to manage the
+  request. However during opal init, opal pollers may not be called, it
+  depends in the context in which the i2c request is made. If the
+  pollers are not called, the timers are not checked and we can end up
+  with an i2c request which will not move foward and skiboot hangs.
+
+  Fix it by explicitly checking the timers if we are waiting for an i2c
+  request to complete and it seems to be taking a while.
+
+- opal-prd: hservice: Enable hservice->wakeup() in BMC
+
+  This patch enables HBRT to use HYP special wakeup register in openBMC
+  which until now was only used in FSP based machines.
+
+  This patch also adds a capability check for opal-prd so that HBRT can
+  decide if the host special wakeup register can be used.
+
+- npu2: Advertise correct TCE page size
+
+  The P9 NPU workbook says that only 4K/64K/16M/256M page size are supported
+  and in fact npu2_map_pe_dma_window() supports just these but in absence of
+  the "ibm,supported-tce-sizes" property Linux assumes the default P9 PHB4
+  page sizes - 4K/64K/2M/1G - so when Linux tries 2M/1G TCEs, we get lots of
+  "Unexpected TCE size" from npu2_tce_kill().
+
+  This advertises TCE page sizes so Linux could handle it correctly, i.e.
+  fall back to 4K/64K TCEs.
