+
+skiboot 6.0.12 was released on Monday November 12th, 2018. It replaces
+:ref:`skiboot-6.0.11` as the current stable release in the 6.0.x series.
+
+It is recommended that 6.0.12 be used instead of any previous 6.0.x version
+due to the bug fixes it contains.
+
+The bug fixes are:
+
+- hiomap: quieten warning on failing to move a window
+
+  This isn't *necessarily* an error that we should complain loudly about.
+  If, for example, the BMC enforces the Read Only flag on a FFS partition,
+  opening a write window *should* fail, and we do indeed test this in
+  op-test.
+
+  Thus we deal with the error in a well known path: returning an error
+  code and then it's eventually a userspace problem.
+- libflash/ipmi-hiomap: Respect daemon presence and flash control
