      Release Notes: When a login is terminated by a system halt or reboot, this release prints 'down' as the logout time. It will correctly display login times with negative values.

      •  29 Oct 2009 19:43

        Release Notes: The cleaning of the wtmp records no longer leaves any trace, even in the raw output. The listing of user logins was improved.

        •  15 Jan 2009 10:07

          Release Notes: The raw ('--raw') output was highly improved. The whole wtmp database is dumped if no user is specified. An error code of 1 is returned if the editing of the wtmp file fails. Unknown fake users are not accepted when patching the wtmp file. Timestamps are always preserved when editing the wtmp file (the '--preserve' option has been removed).

          •  25 Dec 2008 19:00

            Release Notes: Now it's possible to replace a user logged at a given time or in all the records of the wtmp database with another one.
