New features of SCCS-5.04:

The upcoming SCCS-6.0 will introduce a new SCCS history file format that
intentionally causes historic SCCS implementations to abort (to prevent file
corruption) but that can be easily converted back into a SCCS-5.x compliant 
history file using a conversion program. This conversion will not cause a loss
of information as the new information will be encoded as special comment that
is accepted by all other SCCS implementations except for currently GNU "CSSC". 

See the file TODO_V6 for more information.

Please join the discussion mainling list for the development of enhancements on:

	http://lists.berlios.de/mailman/listinfo/sccs-devel
	sccs-devel@lists.berlios.de

The next task for SCCS is to introduce a changeset file that brackets a group 
of single file changes into a change set related to a commit.

New features included with SCCS-5.04:

-	SCCS sccscvt new program to convert between SCCS v4 and SCCS v6 history
	file format.

-	SCCS sccslog now understands the enhanced time format from the 
	SCCS v6 history file format.

-	The "sccs" command now also supports "sccs cvt" for the command "sccscvt"

-	The SEE ALSO section of most man pages has been reworked

-	SCCS admin now computes a checksum for the file content when called
	as admin -ifile s.file.

-	SCCS admin now prints full path names in warnings when a file does not
	end in a newline or includes a line that starts qith ^A in V6 mode.

-	SCCS delta no longer reads the new file two times before adding the delta.

-	SCCS delta is now more correct when checking whether a file includes
	SCCS keywords to expand.

-	SCCS delta now computes a checksum for the new SID specific content of 
	the file.

-	New SCCS SID specific history file extension "^AS ..."

-	New error code "co27" allows to distinguish a general chescksum error from
	a SID specific checksum error.

-	SCCS prs -d supports :SX: to print SID specific history file extension

-	SCCS prt now prints SID specific history file extensions

-	SCCS val now does not print a format error message when
	SID specific history file extensions are seen in a SCCS v6 history file

-	libcomobj/date_ab.c now uses a specialized and speed up version of gN()
	for date_ab().

-	libcomobj/getline.c now uses a completely new algorithm to compute
	the checksum with better performance.

-	libcomobj/putline.c now tries to avoid to compute the checksum
	when in copy mode.

-	libschily/mkgmtime.c is now faster then previous release.
	Make it also correct when tm_month < 0 or > 11.

-	libschily/sidext_ab.c and libschily/sidext_ba.c new files to deal with
	SID specific extensions.

SCCS-5.04 is now 20% faster than SCCS-5.03.

SCCS-5.04 is 2.5x faster than Sun SCCS and consumes 4.7x less CPU time than Sun SCCS.
SCCS-5.04 is 5.3x faster than RCS and consumes 6.4x less CPU time than RCS.


SCCS now has been tested to compile and work on the following platforms:

-	SunOS-4.x

-	SunOS-5.x (Solaris 2.x, 7, 8, 9, 10, 11)

-	FreeBSD

-	HP-UX

-	Linux

-	Mac OS X

-	AIX

-	IRIX

-	VMS

-	Cygwin

The portability now reached a state that should allow SCCS to compile 
and run on other platforms too. SCCS compiles and has been verified
on all major platforms.
