15.01.1992, Thomas Koenig

Fixed a bug combination in at/atrun which meant that files could
be deleted before being executed, now fiddling with the x - bit
(for execution) and the r - bit (for deletion).

Added -d, -l and -q options with handling.

16.01.1992, Thomas Koenig

Fixed a bug in atrun, where the wrong letters from the filename
was used for determining niceness.

Added making a distribution, hopefully without clobbering too much...

Released as 1.1.

26.01.1992

Changed mail command in at.c from using -s to explicit subject line.
Made the Makefile a bit easier to configure, fixed a bug with the
name of the spool directory.

Released as 1.1a.

14.04.1992

Now uses strftime() for showing running time, fixed daylight saving time
bug, corrected handling of login names, and let at.c run suid root because
of chown problem.

Included 386bsd-diffs care of Jonas Olsson (ljo@po.cwru.edu).  Thanks
Jonas!
Released as 1.2.

12.09.1993

Worked over very extensive English - language time support by
David Parsons (orc@pell.chi.il.us).  Thanks a lot!

13.09.1993

Reworked atrun.c to be more robust for syntax errors in the batch file.

18.09.1993

Added -m option with support

29.09.1993

Tried merging the BSD patches back in; no way to check, unfortunately.
Added -V (version) option and not exporting DISPLAY, TERM and _.

Released as 2.0.

03.10.1993

Cleared things up so g++ will accept them; switched to a header
structure where every *.c - file has its corresponding *.h file
in which the things it exports are put.

Fixed a security bug; released as 2.1

12.10.1993

Found a more elegant way around the security bug; fixed bug which
meant that only one job was run correctly per invocation.

Released as 2.2.

16.10.1993

Fixed a leftover test from 2.1 which resulted in -f being broken;
actually exported the variables generated in the resulting
shell script.

Released as 2.3.

Fixed a bug resulting in wrong number of minutes for time in the
format of 1630.

Released as 2.4.

Tried to reduce privilege to absolute minimum; alas, there's no way
under Linux for a setgid <someting> program to give away a file to
the original user's group without root privileges.

Released as 2.5.

Hacked up Configure script.
