You can find the latest builds from ftp://ftp.dd-wrt.com/betas/2017 but please choice builds higher then 06-01-2017-r32170 but before you upgrade! please type in your router model here to rule out any known bugs! http://svn.dd-wrt.com/ if okay then go a head and upgrade
Keeo in mind any lower builds dont have the vulnerabilities patch https://ostif.org/the-openvpn-2-4-0-audit-by-ostif-and-quarkslab-results
I can myself confirm build ftp://ftp.dd-wrt.com/betas/2017/07-19-2017-r32753/ Is working great for my TP-Link router
