* Password and group data is now cached for fast lookup.
- * Sudo will use the supplemental group vector if it is present in addition
- to doing string comparisons of the group members. This is useful for
- systems with nsswitch.conf where group entries can be in either /etc/group
- or some other database (NIS, NIS+, LDAP, etc) and getgrnam() only returns
- data from one source.
-
* The file descriptor at which sudo starts closing all open files is now
configurable via sudoers and, optionally, the command line.
- * Visudo can now handle VISUAL and EDITOR environment variables that contain
- command line arguments.
-
* Visudo will now warn about aliases that are defined but not used.
