Hi all,

I just pushed and tagged skiboot 5.2.4. Release notes below:

skiboot-5.2.4
-------------

skiboot-5.2.4 was released on Tuesday July 12th, 2016.

This is the 5th stable release of skiboot 5.2, the new stable release of
skiboot (first release with 5.2.0 on March 16th 2016).

Skiboot 5.2.4 replaces skiboot-5.2.3 as the current stable version, which was
released on June 30th 2016. Over skiboot-5.2.3, skiboot 5.2.4 contains bug
fixes to make skiboot more resilient to errors in the XSCOM engine and some
build improvements for the pflash utility.

skiboot-5.2.4 contains all bug fixes as of skiboot-5.1.16.

This is the second release that will follow the (now documented) Skiboot
