This is the Condor source distribution version 4.1.3b.  This is a beta
test, but should be fairly stable as it is based largely on the results
of the 4.1b beta testing.

		Highlights of the changes from version 4.1.0b

Suns:   Due to the different format used by SunOS for core files, the
	checkpointing code previously used was *very* inefficient.  In
	fact it was so inefficient that in some cases condor jobs would
	spend allmost all their time checkpointing, and make very
	little progress.  This has been fixed for all programs which
	use the stack pointer in the conventional way.  This includes
	most C and Fortran programs.  There is still another case where
	the new code will also be very inefficient and that is the case
	where the application program manipulates the stack pointer so
	that it is actually pointing into the "data" area.  This will
	generally be true for programs which use threads or coroutines.
	We expect to fix this problem in the next realease.

R6000:	Checkpointing is now supported for R6000's running AIX3.1.
	We have not yet tried to build Condor on an AIX3.2 machine,
	but have some experience to indicate that at least binaries
	compiled under 3.1 will work on 3.2 machines.  We will be
	building Condor for 3.2 machines in the near future.

NFS:	Previously a bug existed in the code which condor uses to
	access remotely mounted file systems.  This bug only
	happened when the number of mounted systems was fairly
	large (around 40), and is now fixed.


We have tested this code on the following platforms:

	Sun 4, (SPARC) machines running SunOS 4.1 and 4.1.1
	DECstation 3100 and 5000 series machines running Ultrix 4.2
	IBM R6000 series machines running AIX3.1.5

We hope to begin supporting the following platforms sometime in the
not too distant future:

	HP9000-700 machines running HPUX 8
	Silicon Graphics 4D workstations running IRIX 4.0

We will no longer be supporting these platforms:
	IBM RT's
	Sun 3's (68000 based)
	HP Bobcats (68000 based)

The following bugs are known and remain in this distribution:
	1. On R6000s the process which detects keyboard and mouse activity
	   may miss some events.  This generally happens when the motif
	   window manager (mwm) is running.  We expect to fix this in the
	   next distribution.

Postscript ready documentation is included in the "doc/POSTSCRIPT"
directory.  Line printer ready versions of the "man pages" are included
in the "doc/CAT" directory.  Documents other than the man pages cannot
be printed on a line printer because they contain postscript figures.
If you cannot print postscript files, send me your physical mail
address (via email if you can), and I will send you printed copies.

Hints:	If you are upgrading from version 4.1b, please save copies of all
	the files in your "config" directory as well as any changes to
	"condor_config" or "condor_config.local".  There are some changes
	to the new config files, so you cannot just copy in your old ones, but
	knowing what customization you did last time should make it very
	easy to customize the new ones.
