    Release Notes: A POSIX compliance bug in prs(1) that was introduced around 1984 by an undocumented change has been fixed. Some artificial limitations in the programs val(1) and vc(1) have been removed. The libraries "comobj", "mpw" and "cassi" have been rewritten to work around various linker bugs found on Mac OS X. A lot of fundamental basic features have been introduced in preparation for the upcoming support for changesets.

      Release Notes: A new program, rcs2sccs, converts RCS history files to SCCS. A new sccs subcommand, istext, checks whether a file may be archived as unencoded text file. A new sccs subcommand, editor, allows you to automatically edit files regardless of whether they need to be checked out for editing first. The patch program was added in preparation for future releases that support importing changeset deltas. SCCS help now includes online help for all sccs programs. SCCS help now prints a command overview with no args.

        Release Notes: SCCS (using the SCCS v6 history file format) now includes a SID specific additional checksum. A new program, sccscvt(1), was added to convert SCCS v4 history files into SCCS v6 history files and vice versa and to compute additional checksums for all releases. The performance was improved by another 20% compared to SCCS 5.03.

            Release Notes: This is the first step towards the upcoming version 6. SCCS is now allowed to archive files as text files (without using uuencode) even when they do not end on a newline or when there are lines that start with ^A. SCCS now only uses about a quarter of the virtual memory previous versions needed. Further performance improvements were made, so SCCS is now twice as fast as its predecessor from Sun. Autoconf now supports cross compilation.

              Release Notes: The sccs(1) command now supports working on directory trees using -R. All date related limits have been removed for 64-bit versions of the programs. 32-bit programs work until year 2068 if the OS supports time and file time stamps to 2068. SCCS performance has been enhanced to fix the performance problems that appeared on UNIX past 1986. SCCS admin now supports fast mass entering of files. Support for new platforms (AIX, IRIX, Haiku, VMS) has been added.

                Release Notes: SCCS admin now supports a new option -N for efficient mass entering of files. Several smaller old bugs have been fixed. Several enhancements in the man pages have been introduced.

                  Release Notes: SCCS delta now uses a faster method to close open files (which is important on AIX with 65535 files). The new function zrealloc() is used on platforms that do not support realloc(NULL, size). A workaround for a deficit in setvbuf() on Linux was introduced. A workaround for platforms with a slow mktime() implementation (e.g. AIX, Linux, SunOS-4.1) was introduced. SCCS is once again always faster than RCS regardless of the OS platform.

                    Release Notes: The prs(1) keywords :G: and :D_: were added for BitKeeper compatibility. diff -u now includes nanoseconds in the timestamp. The bugs in the lock mechanism introduced by Sun have been fixed. A bug introduced by Sun related to automatic recognition of binary files has been fixed. SCCS no longer calls link(2) and thus now should work on BeOS and similar platforms. The SCCS performance was enhanced.

                      Release Notes: SCCS "admin -fy s.foo" now not only turns off keyword expansion but also turns off the "No iy keyword" warning for "admin", "delta", and "get". SCCS get now implements a new -o (original file date) option. Time stamp handling now is more robust and supports times before 1970 and times past 2068 (including 3000). 4-digit year numbers may be specified for the cut-off time. A verification/validation test suite has been added to "sccs/tests".
