Hello, I mark the gnutls 3.4.x releases as the current stable branch. That means that only minor features may enter this branch and new development is diverted to the 3.5.x (master) branch. For an overview of the 3.4.x releases see my blog post: http://nmav.gnutls.org/2015/11/an-overview-of-gnutls-34x.html regards, Nikos
