Oracle VirtualBox 5.0.20 is a pretty small release that comes only one and a half weeks after the previous maintenance build, VirtualBox 5.0.18, which introduced initial support for the upcoming Linux 4.6 kernel. Changes in today’s VirtualBox 5.0.20 release include more fixes for the Linux kernel 4.5 series, especially when the CONFIG_NET_CLS_ACT variable is enabled, support for listing processor features on VBoxManage’s list hostinfo, TCP support in the DNS proxy feature, as well as better handling of port-forwarding rules.
