  $ more /usr/src/UPDATING
  Updating Information for FreeBSD STABLE users

  This file is maintained by imp@village.org.  Please send new entries
  directly to him.  See end of file for further details.  A reverse
  chronology since 4.0 was released is included, followed by the common
  items quick how-tos, followed by entries for versions of -current
  prior to 4.0 Release.

  20010611:
          The TCP_RESTRICT_RST option has been removed. You should entirely
          remove it from your kernel configuration.

          The same functionality is available from the blackhole(4) MIB.
