SCCS is an implementation of the POSIX standard Source Code Control System. It is based on the original UNIX SCCS code provided by Sun as part of OpenSolaris and was made portable to other platforms.

The sccslog(1) command now implements a new option -a to control the way sccslog collects deltas with the same delta comment. The diff(1) command delivered with SCCS now outputs the correct time stamp format for unified diffs (-u) as required by POSIX. SCCS val now can check for non-monotone time stamps in SCCS history files, for missing user names in the delta table, and for a defective statictics line. SCCS admin and delta now support the option -o to use the time stamp of the original file.
