Disabled by default, enable via "HiddenServicePoW" in torrc * Implement conflux traffic splitting * Directory authorities and relays now interact properly with directory authorities if they change addresses - tor 0.4.7.14: * bugfix affecting vanguards (onion service), and minor fixes - Enable support for scrypt() Patch Instructions: To install this openSUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
