On July 21, the kernel community lost Dan Williams, one of its most beloved contributors. Dave Hansen and Thomas Gleixner, both of whom worked with Williams extensively, have written an obituary and allowed LWN to publish it. He will be deeply missed, but he has left us with a lot to remember him by.

Version 2.44 of the GNU C Library has been released. Changes include a new /etc/tunables.conf file for the system-wide setting of tunable parameters, a new tunable to control the use of transparent huge pages for read-only executable segments, a number of math-function improvements, a handful of security fixes, and more.
