skiboot v5.9-rc3 was released on Wednesday October 18th 2017. It is
the third release candidate of skiboot 5.9, which will become the new
stable release of skiboot following the 5.8 release, first released
August 31st 2017.

skiboot v5.9-rc3 contains all bug fixes as of skiboot-5.4.8 and
skiboot-5.1.21 (the currently maintained stable releases). We do not
currently expect to do any 5.8.x stable releases.

For how the skiboot stable releases work, see Skiboot stable tree
rules and releases for details.

The current plan is to cut the final 5.9 by October 20th, with skiboot
5.9 being for all POWER8 and POWER9 platforms in op-build v1.20 (Due
October 18th). This release will be targetted to early POWER9 systems.

Over skiboot-5.9-rc2, we have the following changes:

* Improvements to vpd device tree entries

  Previously we would miss some properties

* Revert "npu2: Add vendor cap for IRQ testing"

  This reverts commit 9817c9e29b6fe00daa3a0e4420e69a97c90eb373 which
  seems to break setting the PCI dev flag and the link number in the
  PCIe vendor specific config space. This leads to the device driver
  attempting to re-init the DL when it shouldn't which can cause

* hw/imc: Fix IMC Catalog load for DD2.X processors


  Add a new CPU reinit flag, "TM Suspend Disabled", which requests
  that CPUs be configured so that TM (Transactional Memory) suspend
  mode is disabled.

  Currently this always fails, because skiboot has no way to query the
  state. A future hostboot change will add a mechanism for skiboot to
  determine the status and return an appropriate error code.
