Release Notes: Adds support for regular expressions in the editing mode.
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.
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.
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).
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.
Release Notes: A new '-t'/'--time' option was added for deleting a login occurring at a given time. The list of the logins is now printed in the format used by the 'last' command.
Release Notes: This release will print the list of all users logged in and out with session length in '--list' mode. All gcc warnings when compiling with the '-pedantic' and '-ansi' flags enabled have been fixed.
Release Notes: Fixes were made to compile and run on AIX (and possibly other non-Linux POSIX-compliant operating systems).
Release Notes: This release adds an '-l|--list' option to list the user logins with terminal and login date. The '-t|--test' and '-u|--user' command line options have been removed. This release will only use POSIX.1-2001 functions to support non-Linux systems. When cleaning up a block, it will also fill 'ut_host' and 'ut_addr_v6' with zeroes.
Release Notes: Support for GNU command-line long options was added. The tool now fails if the calling process can't access the file in write mode instead of saying: "0 blocks modified". A better help message with a couple of usage examples was included.
