As L4 itself is now deprecated and it's successors, L4.sec and L4ng, are not ready yet, efforts are directed toward designing from scratch this new Hurd. +There is an effort to create a completely new system design (for now called ngHurd, or Hurd-ng or HurdNG), which originated from the Hurd/L4 port. -There are discussions on the desired features, and discussions about it's design principles and core properties. +The original Hurd/L4, which was meant to be mostly a direct port of the existing Hurd design to a new microkernel, has been abandoned by it's main developers, because some technical issues with the L4 Pistachio kernel turned out to be very fundamental. While reeveluating the design (and upcoming new L4 variants), the developers picked up some new ideas, and decided that now they rather want to work on a completely different design, which combines some of the original Hurd ideas with concepts from Jonathan Shapiro's high security EROS and Coyotos systems. + +There has been numerous endless discussions on the l4-hurd mailing list about these new ideas.
