6.2 release ports packages gone missing?

[Sean Bruno]

I guess due to the 6.3 release all the 6.2 release packages got 
deleted?  Why delete them?  Are they placed somewhere else?

$ pkg_add -nr net-snmp
Error: FTP Unable to get 
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6.2-release/Latest/net-snmp.tbz:
