rather than using a broadcast address. Thanks to a patch from David
Cantrell at Red Hat.
+- Added client support for setting interface MTU and metric, thanks to
+ Roy "UberLord" Marples <roy@marples.name>.
+
Changes since 4.1.0 (bug fixes)
- Validate the argument to the -p option.
- Various compilation fixes have been included for the memory related
DEBUG #defines in includes/site.h.
+- Fixed Linux client script 'unary operator expected' errors with DHCPv6.
+
+- Fixed setting hostname in Linux hosts that require hostname argument
+ to be double-quoted. Also allow server-provided hostname to
+ override hostnames 'localhost' and '(none)'.
+
Changes since 4.1.0b1
- A missing "else" in dhcrelay.c could have caused an interface not to
