Late-Breaking News

[2021-04-05] A very late issue was discovered in the /usr/bin/dc program. The "P" command does not correctly pop the top of stack value and this will break complex scripts that continue after printing a result. The /usr/bin/bc program is not affected, since it does not depend on dc as its execution engine.

[2021-04-14] An issue was discovered where during an upgrade, when the kernel is new but /sbin/ifconfig is still the previous version, VLAN interfaces are configured with an invalid ethernet protocol type. This causes the VLAN interfaces to send invalid traffic, resulting in non-functional networking. Once the updated /sbin/ifconfig binary is installed, VLANs are created correctly. When depending on network access via VLANs during the upgrade, it is suggested to install the new world (run the second freebsd-update install) before rebooting.
