All its = interesting facilities have been subsumed into OpenWrt mainline code. - The OpenWrt project has a fork - LEDE (http://lede-project.org) It = remains to be seen what effect this will have on our anti-Bufferbloat = effort. - RIP: the original www.bufferbloat.net server. Hopefully someone can = pick up the pieces (even for historical purposes) as we re-deploy the = information to a new (non-Redmine) system. What else happened this year?
