+skiboot-6.3.3
+==============
+
+skiboot 6.3.3 was released on Wednesday Aug 6th, 2019. It replaces
+:ref:`skiboot-6.3.2` as the current stable release in the 6.3.x series.
+
+It is recommended that 6.3.3 be used instead of any previous 6.3.x version
+due to the bug fixes it contains.
+
+Bug fixes included in this release are:
+
+- struct p9_sbe_msg doesn't need to be packed
+
+  Only the reg member is sent anywhere (via xscom_write), so the structure
+  does not need to be packed.
+
+::
+  Fixes GCC9 build problem:
+  hw/sbe-p9.c: In function ‘p9_sbe_msg_send’:
+  hw/sbe-p9.c:270:9: error: taking address of packed member of ‘struct p9_sbe_msg’ may result in an unaligned p
+  ointer value [-Werror=address-of-packed-member]
+    270 |  data = &msg->reg[0];
+        |         ^~~~~~~~~~~~
+
+- hdata/vpd: fix printing (char*)0x00
+  GCC9 now catches this bug:
+
+::
+  In file included from hdata/vpd.c:17:
+  In function ‘vpd_vini_parse’,
+      inlined from ‘vpd_data_parse’ at hdata/vpd.c:416:3:
+  /skiboot/include/skiboot.h:93:31: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
+     93 | #define prlog(l, f, ...) do { _prlog(l, pr_fmt(f), ##__VA_ARGS__); } while(0)
+          |                               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  hdata/vpd.c:390:5: note: in expansion of macro ‘prlog’
+    390 |     prlog(PR_WARNING,
+          |     ^~~~~
+  hdata/vpd.c: In function ‘vpd_data_parse’:
+  hdata/vpd.c:391:46: note: format string is defined here
+    391 |           "VPD: CCIN desc not available for: %s\n",
+          |                                              ^~
+  cc1: all warnings being treated as errors
+
+- errorlog: Prevent alignment error building with gcc9.
+
+::
+  Fixes this build error:
+  [ 52s] hw/fsp/fsp-elog-write.c: In function 'opal_elog_read':
+  [ 52s] hw/fsp/fsp-elog-write.c:213:12: error: taking address of packed member of 'struct errorlog' may result
+  in an unaligned pointer value [-Werror=address-of-packed-member]
+  [ 52s] 213 | list_del(&log_data->link);
+  [ 52s] | ^~~~~~~~~~~~~~~
+
+- Support BMC IPMI heartbeat command
+
+  A few years ago, the OpenBMC code added support for a "heartbeat"
+  command to send to the host. This command is used after the BMC is reset
+  to check if the host is running. Support was never added to the host
+  side however so currently when the BMC sends this command, this appears
+  in the host console:
+  IPMI: unknown OEM SEL command ff received
+
+  There is no response needed by the host (other then the low level
+  acknowledge of the command which already occurs). This commit
+  handles the command so the error is no longer printed (does nothing with
+  the command though since no action is needed). Here's the tested output
+  of this patch in the host console (with debug enabled):
+  IPMI: BMC issued heartbeat command: 00
+
+- Add: add mihawk platform file
