3proxy-0.9.7 Released July, 4 2026

+ PCRE2 and SSL/TLS code moved from plugins into main 3proxy binary; dynamic linking with ssl/pcre by default, STATIC/LIBSTATIC options for static linking
+ Unix sockets support for parent proxies, tcppm, internal listeners and -i option; abstract (fileless) unix sockets on Linux
+ ssl_client_mode = 3 to use 'secure' parent types: https, tcps, socks5s, connect+s, etc.
+ New authcache types: cacheacl, dstaddr, dstport, dsthost, dstoper, srvaddr, srvport; authcache is now configurable per service
+ Hashtables for password lists and authcache, faster password lookups
+ 3proxy_crypt: new internal password hashing replacing mycrypt
+ udppm switched to hashtables and supports multiple connections
+ SOCKSv5 UDP parent support; -Ne/-Ni NAT options
+ Docker images for more platforms, signed; DLLs signed; public cert added to build
+ Grace sleep and linger on connection close; correctly process half-closed connections
+ Allow setting internal/external network namespaces on Linux
