Mapping DHCPv4 Options to DHCPv6 Options

Hi Roy,
The dhcpcd.conf man page says the following:
option option
Requests the option from the server. It can be a variable to be used in dhcpcd-run-hooks(8)<http://roy.marples.name/man/html8/dhcpcd-run-hooks.html> or the numerical value. You can specify more options separated by commas, spaces or more option lines. Prepend dhcp6_ to option to request a DHCPv6 option. DHCPv4 options are mapped to DHCPv6 where applicable.
Has the mapping of DHCPv4 options to DHCPv6 options changed in the last few releases? I seem to remember that "option domain_search" would cause both DHCPv4 Option 119 and DHCPv6 Option 24 to be included in DHCPv4 Option 55 and DHCPv6 Option 6 respectively. Also "option fqdn" would cause both DHCPv4 Option 81 and DHCPv6 Option 39 to be included. It seems that now I have to specify "option dhcp6_domain_search" and "option dhcp6_fqdn" to get these to appear in DHCPv6 Option 6.
