Tue Apr  7 15:55:25 1992  Brian Berliner  (berliner at sun.com)

	* Changes between CVS 1.3 Beta-3 and official CVS 1.3!

	* A new shell script is provided, "./cvsinit", which can be run at
	install time to help setup your $CVSROOT area.  This can greatly
	ease your entry into CVS usage.

	* The INSTALL file has been updated to include the machines on
	which CVS has compiled successfully.  I think CVS 1.3 is finally
	portable.  Thanks to all the Beta testers!

	* Support for the "editinfo" file was contributed.  This file
	(located in $CVSROOT/CVSROOT) can be used to specify a special
	"editor" to run on a per-directory basis within the repository,
	instead of the usual user's editor.  As such, it can verify that
	the log message entered by the user is of the appropriate form
	(contains a bugid and test validation, for example).

	* The manual pages cvs(1) and cvs(5) have been updated.

	* The "mkmodules" command now informs you when your modules file
	has duplicate entries.

	* The "add" command now preserves any per-directory sticky tag when
	you add a new directory to your checked-out sources.

	* The "admin" command is now a fully recursive interface to the
	"rcs" program which operates on your checked-out sources.  It no
	longer requires you to specify the full path to the RCS file.

	* The per-file sticky tags can now be effectively removed with
	"cvs update -A file", even if you had checked out the whole
	directory with a per-directory sticky tag.  This allows a great
	deal of flexibility in managing the revisions that your checked-out
	sources are based upon (both per-directory and per-file sticky
	tags).

	* The "cvs -n commit" command now works, to show which files are
	out-of-date and will cause the real commit to fail, or which files
	will fail any pre-commit checks.  Also, the "cvs -n import ..."
	command will now show you what it would've done without actually
	doing it.

	* Doing "cvs commit modules" to checkin the modules file will no
	properly run the "mkmodules" program (assuming you have setup your
	$CVSROOT/CVSROOT/modules file to do so).

	* The -t option in the modules file (which specifies a program to
	run when you do a "cvs rtag" operation on a module) now gets the
	symbolic tag as the second argument when invoked.

	* When the source repository is locked by another user, that user's
	login name will be displayed as the holder of the lock.

	* Doing "cvs checkout module/file.c" now works even if
	module/file.c is in the Attic (has been removed from main-line
	development).

	* Doing "cvs commit */Makefile" now works as one would expect.
	Rather than trying to commit everything recursively, it will now
	commit just the files specified.

	* The "cvs remove" command is now fully recursive.  To schedule a
	file for removal, all you have to do is "rm file" and "cvs rm".
	With no arguments, "cvs rm" will schedule all files that have been
	physically removed for removal from the source repository at the
	next "cvs commit".

	* The "cvs tag" command now prints "T file" for each file that was
	tagged by this invocation and "D file" for each file that had the
	tag removed (as with "cvs tag -d").

	* The -a option has been added to "cvs rtag" to force it to clean
	up any old, matching tags for files that have been removed (in the
	Attic) that may not have been touched by this tag operation.  This
	can help keep a consistent view with your tag, even if you re-use
	it frequently.

Sat Feb 29 16:02:05 1992  Brian Berliner  (berliner at sun.com)

	* Changes between CVS 1.3 Beta-2 and CVS 1.3 Beta-3

	* Many portability fixes, thanks to all the Beta testers!  With any
	luck, this Beta release will compile correctly on most anything.
	Hey, what are we without our dreams.

	* CVS finally has support for doing isolated development on a
	branch off the current (or previous!) revisions.  This is also
	extremely nice for generating patches for previously released
	software while development is progressing on the next release.
	Here's an example of creating a branch to fix a patch with the 2.0
	version of the "foo" module, even though we are already well into
	the 3.0 release.  Do:

		% cvs rtag -b -rFOO_2_0 FOO_2_0_Patch foo
		% cvs checkout -rFOO_2_0_Patch foo
		% cd foo
		[[ hack away ]]
		% cvs commit

	A physical branch will be created in the RCS file only when you
	actually commit the change.  As such, forking development at some
	random point in time is extremely light-weight -- requiring just a
	symbolic tag in each file until a commit is done.  To fork
	development at the currently checked out sources, do:

		% cvs tag -b Personal_Hack
		% cvs update -rPersonal_Hack
		[[ hack away ]]
		% cvs commit

	Now, if you decide you want the changes made in the Personal_Hack
	branch to be merged in with other changes made in the main-line
	development, you could do:

		% cvs commit		     # to make Personal_Hack complete
		% cvs update -A		     # to update sources to main-line
		% cvs update -jPersonal_Hack # to merge Personal_Hack

	to update your checked-out sources, or:

		% cvs checkout -jPersonal_Hack module

	to checkout a fresh copy.

	To support this notion of forked development, CVS reserves
	all even-numbered branches for its own use.  In addition, CVS
	reserves the ".0" and ".1" branches.  So, if you intend to do your
	own branches by hand with RCS, you should use odd-numbered branches
	starting with ".3", as in "1.1.3", "1.1.5", 1.2.9", ....

	* The "cvs commit" command now supports a fully functional -r
	option, allowing you to commit your changes to a specific numeric
	revision or symbolic tag with full consistency checks.  Numeric
	tags are useful for bringing your sources all up to some revision
	level:

		% cvs commit -r2.0

	For symbolic tags, you can only commit to a tag that references a
	branch in the RCS file.  One created by "cvs rtag -b" or from
	"cvs tag -b" is appropriate (see below).

	* Roland Pesch <pesch@cygnus.com> and K. Richard Pixley
	<rich@cygnus.com> were kind enough to contribute two new manual
	pages for CVS: cvs(1) and cvs(5).  Most of the new CVS 1.3 features
	are now documented, with the exception of the new branch support
	added to commit/rtag/tag/checkout/update.

	* The -j options of checkout/update have been added.  The "cvs join"
	command has been removed.

	With one -j option, CVS will merge the changes made between the
	resulting revision and the revision that it is based on (e.g., if
	the tag refers to a branch, CVS will merge all changes made in
	that branch into your working file).

	With two -j options, CVS will merge in the changes between the two
	respective revisions.  This can be used to "remove" a certain delta
	from your working file.  E.g., If the file foo.c is based on
	revision 1.6 and I want to remove the changes made between 1.3 and
	1.5, I might do:

		% cvs update -j1.5 -j1.3 foo.c		# note the order...

	In addition, each -j option can contain on optional date
	specification which, when used with branches, can limit the chosen
	revision to one within a specific date.  An optional date is
	specified by adding a colon (:) to the tag, as in:

		-jSymbolic_Tag:Date_Specifier

	An example might be what "cvs import" tells you to do when you have
	just imported sources that have conflicts with local changes:

		% cvs checkout -jTAG:yesterday -jTAG module

	which tells CVS to merge in the changes made to the branch
	specified by TAG in the last 24 hours.  If this is not what is
	intended, substitute "yesterday" for whatever format of date that
	is appropriate, like:

		% cvs checkout -jTAG:'1 week ago' -jTAG module

	* "cvs diff" now supports the special tags "BASE" and "HEAD".  So,
	the command:

		% cvs diff -u -rBASE -rHEAD

	will effectively show the changes made by others (in unidiff
	format) that will be merged into your working sources with your
	next "cvs update" command.  "-rBASE" resolves to the revision that
	your working file is based on.  "-rHEAD" resolves to the current
	head of the branch or trunk that you are working on.

	* The -P option of "cvs checkout" now means to Prune empty
	directories, as with "update".  The default is to not remove empty
	directories.  However, if you do "checkout" with any -r options, -P
	will be implied.  I.e., checking out with a tag will cause empty
	directories to be pruned automatically.

	* The new file INSTALL describes how to install CVS, including
	detailed descriptions of interfaces to "configure".

	* The example loginfo file in examples/loginfo has been updated to
	use the perl script included in contrib/log.pl.  The nice thing
	about this log program is that it records the revision numbers of
	your change in the log message.

	Example files for commitinfo and rcsinfo are now included in the
	examples directory.

	* All "#if defined(__STDC__) && __STDC__ == 1" lines have been
	changed to be "#if __STDC__" to fix some problems with the former.

	* The lib/regex.[ch] files have been updated to the 1.3 release of
	the GNU regex package.

	* The ndbm emulation routines included with CVS 1.3 Beta-2 in the
	src/ndbm.[ch] files has been moved into the src/myndbm.[ch] files
	to avoid any conflict with the system <ndbm.h> header file.  If
	you had a previous CVS 1.3 Beta release, you will want to "cvs
	remove ndbm.[ch]" form your copy of CVS as well.

	* "cvs add" and "cvs remove" are a bit more verbose, telling you
	what to do to add/remove your file permanently.

	* We no longer mess with /dev/tty in "commit" and "add".

	* More things are quiet with the -Q option set.

	* New src/config.h option:  If CVS_BADROOT is set, CVS will not
	allow people really logged in as "root" to commit changes.

	* "cvs diff" exits with a status of 0 if there were no diffs, 1 if
	there were diffs, and 2 if there were errors.

	* "cvs -n diff" is now supported so that you can still run diffs
	even while in the middle of committing files.

	* Handling of the CVS/Entries file is now much more robust.

	* The default file ignore list now includes "*.so".

	* "cvs import" did not expand '@' in the log message correctly.  It
	does now.  Also, import now uses the ignore file facility
	correctly.

	Import will now tell you whether there were conflicts that need to
	be resolved, and how to resolve them.

	* "cvs log" has been changed so that you can "log" things that are
	not a part of the current release (in the Attic).

	* If you don't change the editor message on commit, CVS now prompts
	you with the choice:

		!)reuse this message unchanged for remaining dirs

	which allows you to tell CVS that you have no intention of changing
	the log message for the remainder of the commit.

	* It is no longer necessary to have CVSROOT set if you are using
	the -H option to get Usage information on the commands.

	* Command argument changes:
	checkout:		-P handling changed as described above.
				New -j option (up to 2 can be specified)
				for doing rcsmerge kind of things on
				checkout.
	commit:			-r option now supports committing to a
				numeric or symbolic tags, with some
				restrictions.  Full consistency checks will
				be done.
				Added "-f logfile" option, which tells
				commit to glean the log message from the
				specified file, rather than invoking the
				editor.
	rtag:			Added -b option to create a branch tag,
				useful for creating a patch for a previous
				release, or for forking development.
	tag:			Added -b option to create a branch tag,
				useful for creating a patch for a previous
				release, or for forking development.
	update:			New -j option (up to 2 can be specified)
				for doing rcsmerge kind of things on
				update.

Thu Jan  9 10:51:35 MST 1992 Jeff Polk (polk at BSDI.COM)

	* Changes between CVS 1.3 Beta-1 and CVS 1.3 Beta-2

	* Thanks to K. Richard Pixley at Cygnus we now have function
	prototypes in all the files

	* Some small changes to configure for portability.  There have
	been other portability problems submitted that have not been fixed
	(Brian will be working on those).  Additionally all __STDC__
	tests have been modified to check __STDC__ against the constant 1 
	(this is what the Second edition of K&R says must be true).

	* Lots of additional error checking for forked processes (run_exec)
	(thanks again to K. Richard Pixley)

	* Lots of miscellaneous bug fixes - including but certainly not 
	limited to:
		various commit core dumps
		various update core dumps
		bogus results from status with numeric sticky tags
		commitprog used freed memory
		Entries file corruption caused by No_Difference
		commit to revision broken (now works if branch exists)
		ignore file processing broken for * and !
		ignore processing didn't handle memory reasonably
		miscellaneous bugs in the recursion processor
		file descriptor leak in ParseInfo
		CVSROOT.adm->CVSROOT rename bug
		lots of lint fixes

	* Reformatted all the code in src (with GNU indent) and then 
	went back and fixed prototypes, etc since indent gets confused.  The
	rationale is that it is better to do it sooner than later and now
	everything is consistent and will hopefully stay that way.
	The basic options to indent were: "-bad -bbb -bap -cdb -d0 -bl -bli0 
	-nce -pcs -cs -cli4 -di1 -nbc -psl -lp -i4 -ip4 -c41"  and then
	miscellaneous formatting fixes were applied.  Note also that the 
	"-nfc1" or "-nfca" may be appropriate in files where comments have
	been carefully formatted (e.g, modules.c).

Sat Dec 14 20:35:22 1991  Brian Berliner  (berliner at sun.com)

	* Changes between CVS 1.2 and CVS 1.3 Beta are described here.

	* Lots of portability work.  CVS now uses the GNU "configure"
	script to dynamically determine the features provided by your
	system.  It probably is not foolproof, but it is better than
	nothing.  Please let me know of any portability problems.  Some
	file names were changed to fit within 14-characters.

	* CVS has a new RCS parser that is much more flexible and
	extensible.  It should read all known RCS ",v" format files.

	* Most of the commands now are fully recursive, rather than just
	operating on the current directory alone.  This includes "commit",
	which makes it real easy to do an "atomic" commit of all the
	changes made to a CVS hierarchy of sources.  Most of the commands
	also correctly handle file names that are in directories other than
	".", including absolute path names.  Commands now accept the "-R"
	option to force recursion on (though it is always the default now)
	and the "-l" option to force recursion off, doing just "." and not
	any sub-directories.

	* CVS supports many of the features provided with the RCS 5.x
	distribution - including the new "-k" keyword expansion options.  I
	recommend using RCS 5.x (5.6 is the current official RCS version)
	and GNU diff 1.15 (or later) distributions with CVS.

	* Checking out files with symbolic tags/dates is now "sticky", in
	that CVS remembers the tag/date used for each file (and directory)
	and will use that tag/date automatically on the next "update" call.
	This stickyness also holds for files checked out with the the new
	RCS 5.x "-k" options.

	* The "cvs diff" command now recognizes all of the rcsdiff 5.x
	options.  Unidiff format is available by installing the GNU
	diff 1.15 distribution.

	* The old "CVS.adm" directories created on checkout are now called
	"CVS" directories, to look more like "RCS" and "SCCS".  Old CVS.adm
	directories are automagically converted to CVS directories.  The
	old "CVSROOT.adm" directory within the source repository is
	automagically changed into a "CVSROOT" directory as well.

	* Symbolic links in the source repository are fully supported ONLY
	if you use RCS 5.6 or later and (of course) your system supports
	symlinks.

	* A history database has been contributed which maintains the
	history of certain CVS operations, as well as providing a wide array
	of querying options.

	* The "cvs" program has a "-n" option which can be used with the
	"update" command to show what would be updated without actually
	doing the update, like:  "cvs -n update".  All usage statements
	have been cleaned up and made more verbose.

	* The module database parsing has been rewritten.  The new format
	is compatible with the old format, but with much more
	functionality.  It allows modules to be created that grab pieces or
	whole directories from various different parts of your source
	repository.  Module-relative specifications are also correctly
	recognized now, like "cvs checkout module/file.c".

	* A configurable template can be specified such that on a "commit", 
	certain directories can supply a template that the user must fill
	before completing the commit operation.

	* A configurable pre-commit checking program can be specified which
	will run to verify that a "commit" can happen.  This feature can be
	used to restrict certain users from changing certain pieces of the
	source repository, or denying commits to the entire source
	repository.

	* The new "cvs export" command is much like "checkout", but
	establishes defaults suitable for exporting code to others (expands
	out keywords, forces the use of a symbolic tag, and does not create
	"CVS" directories within the checked out sources.

	* The new "cvs import" command replaces the deprecated "checkin"
	shell script and is used to import sources into CVS control.  It is
	also much faster for the first-time import.  Some algorithmic
	improvements have also been made to reduce the number of
	conflicting files on next-time imports.

	* The new "cvs admin" command is basically an interface to the
	"rcs" program.  (Not yet implemented very well).

	* Signal handling (on systems with BSD or POSIX signals) is much
	improved.  Interrupting CVS now works with a single interrupt!

	* CVS now invokes RCS commands by direct fork/exec rather than
	calling system(3).  This improves performance by removing a call to
	the shell to parse the arguments.

	* Support for the .cvsignore file has been contributed.  CVS will
	now show "unknown" files as "? filename" as the result of an "update"
	command.  The .cvsignore file can be used to add files to the
	current list of ignored files so that they won't show up as unknown.

	* Command argument changes:
	cvs:		Added -l to turn off history logging.
			Added -n to show what would be done without actually
			doing anything.
			Added -q/-Q for quiet and really quiet settings.
			Added -t to show debugging trace.
	add:		Added -k to allow RCS 5.x -k options to be specified.
	admin:		New command; an interface to rcs(1).
	checkout:	Added -A to reset sticky tags/date/options.
			Added -N to not shorten module paths.
			Added -R option to force recursion.
			Changed -p (prune empty directories) to -P option.
			Changed -f option; forcing tags match is now default.
			Added -p option to checkout module to standard output.
			Added -s option to cat the modules db with status.
			Added -d option to checkout in the specified directory.
			Added -k option to use RCS 5.x -k support.
	commit:		Removed -a option; use -l instead.
			Removed -f option.
			Added -l option to disable recursion.
			Added -R option to force recursion.
			If no files specified, commit is recursive.
	diff:		Now recognizes all RCS 5.x rcsdiff options.
			Added -l option to disable recursion.
			Added -R option to force recursion.
	history:	New command; displays info about CVS usage.
	import:		Replaces "checkin" shell script; imports sources
			under CVS control.  Ignores files on the ignore
			list (see -I option or .cvsignore description above).
	export:		New command; like "checkout", but w/special options
			turned on by default to facilitate exporting sources.
	join:		Added -B option to join from base of the branch;
			join now defaults to only joining with the top two
			revisions on the branch.
			Added -k option for RCS 5.x -k support.
	log:		Supports all RCS 5.x options.
			Added -l option to disable recursion.
			Added -R option to force recursion.
	patch:		Changed -f option; forcing tags match is now default.
			Added -c option to force context-style diffs.
			Added -u option to support unidiff-style diffs.
			Added -V option to support RCS specific-version
			keyword expansion formats.
			Added -R option to force recursion.
	remove:		No option changes.  It's a bit more verbose.
	rtag:		Equivalent to the old "cvs tag" command.
			No option changes.  It's a lot faster for re-tag.
	status:		New output formats with more information.
			Added -l option to disable recursion.
			Added -R option to force recursion.
			Added -v option to show symbolic tags for files.
	tag:		Functionality changed to tag checked out files
			rather than modules; use "rtag" command to get the
			old "cvs tag" behaviour.
	update:		Added -A to reset sticky tags/date/options.
			Changed -p (prune empty directories) to -P option.
			Changed -f option; forcing tags match is now default.
			Added -p option to checkout module to standard output.
			Added -I option to add files to the ignore list.
			Added -R option to force recursion.

	Major Contributors:

	* Jeff Polk <polk@bsdi.com> rewrote most of the grody code of CVS
	1.2.  He made just about everything dynamic (by using malloc),
	added a generic hashed list manager, re-wrote the modules database
	parsing in a compatible - but extended way, generalized directory
	hierarchy recursion for virtually all the commands (including
	commit!), generalized the loginfo file to be used for pre-commit
	checks and commit templates, wrote a new and flexible RCS parser,
	fixed an uncountable number of bugs, and helped in the design of
	future CVS features.  If there's anything gross left in CVS, it's
	probably my fault!

	* David G. Grubbs <dgg@ksr.com> contributed the CVS "history" and
	"release" commands.  As well as the ever-so-useful "-n" option of
	CVS which tells CVS to show what it would do, without actually
	doing it.  He also contributed support for the .cvsignore file.

	* Paul Sander, HaL Computer Systems, Inc. <paul@hal.com> wrote and
	contributed the code in lib/sighandle.c.  I added support for
	POSIX, BSD, and non-POSIX/non-BSD systems.

	* Free Software Foundation contributed the "configure" script and
	other compatibility support in the "lib" directory, which will help
	make CVS much more portable.

	* Many others have contributed bug reports and enhancement requests.
	Some have even submitted actual code which I have not had time yet
	to integrate into CVS.  Maybe for the next release.

	* Thanks to you all!

	recently-posted RCS 5.5 distribution with CVS 1.2.  See below for
	other assorted bug-fixes that have been thrown in.

	* ChangeLog (new): Added Emacs-style change-log file to CVS 1.2
	release.  Chronological description of changes between release.

	* README: Small fixes to installation instructions.  My email
