+skiboot-5.5.0
+=============
+
+skiboot-5.5.0 was released on Friday April 7th 2017. It is the new stable
+release of skiboot, taking over from the 5.4 release, first released on
+November 11th 2016.
+
+skiboot-5.5.0 contains all bug fixes as of :ref:`skiboot-5.4.3`
+and :ref:`skiboot-5.1.19` (the currently maintained stable releases).
+
+For how the skiboot stable releases work, see :ref:`stable-rules` for details.
+
+This release is a good level set of POWER9 support for bringup activities.
+If you are doing bringup, it is strongly suggested you continue to follow
+skiboot master.
+
+After skiboot 5.5.0, we move to a regular six week release cycle,
+similar to op-build, but slightly offset to allow for a short stabilisation
+period. Expected release dates and contents are tracked using GitHub milestone
+and issues: https://github.com/open-power/skiboot/milestones

+Changes in skiboot-5.5.0
+------------------------
+
+See changes in the release candidates:
+
+- :ref:`skiboot-5.5.0-rc1`
+- :ref:`skiboot-5.5.0-rc2`
+- :ref:`skiboot-5.5.0-rc3`
+
+Changes since skiboot-5.5.0-rc3
+-------------------------------
+
+- hdat: parse processor attached i2c devices
+
+ Adds basic parsing for i2c devices that are attached to the processor
+ I2C interfaces. This is mainly VPD SEEPROMs.
+- libflash/blocklevel: Add blocklevel_smart_erase()
+
+ With recent changes to flash drivers in linux not all erase blocks are
+ 4K anymore. While most level of the pflash/gard tool stacks were written
+ to not mind, it turns out there are bugs which means not 4K erase block
+ backing stores aren't handled all that well. Part of the problem is the
+ FFS layout that is 4K aligned and with larger block sizes pflash and the
+ gard tool don't check if their erase commands are erase block aligned -
+ which they are usually not with 64K erase blocks.
+
+ This patch aims to add common functionality to blocklevel so that (at
+ least) pflash and the gard tool don't need to worry about the problem
+ anymore.
+- external/pflash: Use blocklevel_smart_erase()
+- external/gard: Use blocklevel_smart_erase()
+- libstb/create-container: Add full container build and sign with imprint keys
+
+ This adds support for writing all the public key and signature fields to the
+ container header, and for dumping the prefix and software headers so they may
+ may be signed, and for signing those headers with the imprint keys.
+- asm: do not set SDR1 on POWER9. This register does not exist in ISAv3.
+
+Testing:
+
+- mambo: Allow setting the Linux command line from the environment
+
+ For automated testing it's helpful to be able to set the Linux command
+ line via an environment variable.
+- mambo: Add util function for breaking on console output

+I am absolutely *thrilled* as to the uptick of reviews and tested-by occuring
+over our 5.4.0 release. Although we are not yet back up to 5.3 era levels for
+review, we're much closer. For tested-by, we've set a new record, which is
+excellent!
