Samuel Thibault presented Saturday at FOSDEM 2016 on the state of GNU Hurd, similar to talk from FOSDEM 2015 as linked above. Progress made to Hurd in the past year includes experimental sound work using the Rump kernel embedded in a library and then directly linked from the multimedia program like MPlayer. USB support for GNU Hurd is being pursued in a similar manner.
Other recent work on GNU Hurd includes initial work on porting the GNU Guix package management system, fixed native fakeroot, SCM_CREDS support, various optimizations, and a new rpcscan tool.
Thibault's current state of GNU Hurd says that 64-bit support has been started, i686 support is in good shape, the DDE Linux 2.6.32 driver layer is working for networking support, IDE and Xorg still work with Hurd, there is an AHCI driver for SATA, Xen PV DomU support is available, and there is the new experimental sound support with the userland Rump.
Future work on GNU Hurd includes 64-bit support, read-ahead, sound and USB rump drivers, startup being done potentially in Scheme, and the potential for a full GNU system when pairing Hurd with Guix.
