+=================
+
+skiboot-5.4.0-rc3 was released on Wednesday November 2nd 2016. It is the
+third release candidate of skiboot 5.4, which will become the new stable
+release of skiboot following the 5.3 release, first released August 2nd 2016.
+
+skiboot-5.4.0-rc3 contains all bug fixes as of :ref:`skiboot-5.3.7`
+and :ref:`skiboot-5.1.18` (the currently maintained stable releases).
+
+For how the skiboot stable releases work, see :ref:`stable-rules` for details.
+
+Since this is a release candidate, it should *NOT* be put into production.
+
+The current plan is to release a new release candidate every week until we
+feel good about it. The aim is for skiboot-5.4.x to be in op-build v1.13, which
+is due by November 23rd 2016.
+
+Over :ref:`skiboot-5.4.0-rc2`, we have a few changes:
+
+- pflash: Fail when file is larger than partition
+  You can still shoot yourself in the foot by passing --force.
+- core/flash: Don't do anything clever for OPAL_FLASH_{READ, WRITE, ERASE}
+  This fixes a bug where opal-prd and opal-gard could fail.
+  Fixes: `<https://github.com/open-power/skiboot/issues/44>`_
+- boot-tests: force BMC to boot from non-golden side
+- fast-reset: Send special reset sequence to operational CPUs only.
+  Fixes fast-reset for cases where there are garded CPUs
+- Secure/Trusted boot: be much clearer about what is being measured where.
+- Secure/Trusted boot: be more resilient to disabled TPM(s).
+- Secure/Trusted boot: The ``force-secure-mode`` NVRAM setting introduced
+  temporarily in :ref:`skiboot-5.4.0-rc2` has changed behaviour. Now, by
+  default, the ``secure-mode`` flag in the device tree is obeyed. As always,
+  any skiboot NVRAM options are in no way ABI, API or supported and may cause
+  unfinished verbose analogies to appear in release notes relating to the
+  dangers of using developer only options.
+- gard: Fix compiler warning on modern GCC targetting ARM 32-bit
+- opal-prd: systemd scripts improvements, only run on supported systems
