We are pleased to announce a new version of CCF, an integrated
environment supporting shared X applications, multi-party
communication, data/file sharing and (coming soon) computation
sharing. For more details, please visit our web page at:
http://ccf.mathcs.emory.edu/
CCF allows two or more researchers to share an X application between
any two machine connected via an intranet or the internet. It is
perfect for letting someone far away "look over your shoulder" at your
computer screen. It supports SunOS 5.5 and higher, IRIX 6.2, and
Linux 2.0.xx.
This release include CCFlauncher, a simple point and click interface
to starting up or joining session and inviting others to your session.
For instance, you can use it to invite people to an internet
conference call very easily.
Support for 16 bit X servers has been "perfected" to the great joy of
many of us. You can use this to display clients that only support 8
or 24 bit graphics on your 16 bit workstation.
Please let us know your experiences with this package. We have
mailing lists for announcements and discussion. To join the lists,

FILE:doc/CHANGES
New since 981124:
* CCFlauncher finally released. CCFlauncher provides a point and
click interface to setting up sessions, picking the tools in a
session, finding a session to join, and inviting others to a
session.
* Fixed bug in 2.2 Linux kernel which prevented ccfaudio from working.
* 16 bit graphics is now fully supported! (Side benefit: You can
run 8 or 24 bit clients on your 16 bit display.)
* Greyscale in 8 bit graphics improved by order of magnitude.
* ccfgui has several new feature for use by ccflauncher. Chief among
these is the ability to highlight several lines in a browser in a
variety of colors.
New since 980827:
NEW STUFF:
* You can now run multiple instances of CCSM and CCFX on the same
machine. They can be in the same session or different sessions.
This is good news for people wanting to test the system or users of
X-terminals and a single server machine.
* The various CCF tools (in 8 bit mode) will no longer user a private
colormap as long as there is room in the current one. CCSM must
still use a private color map.
* The beginning of support for 16 bit graphics. CCSM will run, but
look bad. Others look fine.
BUG FIXES:
* Colors now display correctly in 24 bit graphics running in 32 bit
mode.
* Lots of bug fixes and GUI enhancements for ccfaudio, including many
enhancements for the standalone version documented in the separate
ccfaudio source release. Of primary interest for use with ccsm are:
o Found workaround for MAJOR Solaris flaw in the audio driver.
Sound quality and response time improved by orders of magnitude on
Sun Ultras (and other suns, too).
o multiple tweaks of the ccfaudio ui so that you don't turn on the mic
or speaker accidentally.
New since the second alpha release:
NEW STUFF
* Snapshots! You can save any window to a gif file. Once you've
found a good view of what you are working on you can save it to a
gif file.
* Tools can now appear either on your desktop, or on the virtual
desktop.
BUG FIXES
* Some bugs in the networking code fixed. It is now more stable
(especially under Linux).
* fixes in ccfaudio resizing ability.
* Ccfaudio now correctly indicates correct join time for session
members.
New since the first alpha release:
NEW STUFF:
* Linux support added. See README.Linux.
* Motif applications now work well.
* New session management tools making it easier to manage the ccf
nameserver and reuse session names. See README.sns.new.
* Java based dataspace tool.
* ccsm now takes -geometry and -session command line arguments
ccsm -session -geometry 600x800+1+1
BUG FIXES:
* Latecomers now see all the same windows in the same place with the
same contents.
* Some fixes for CCFaudio in half duplex mode.
* Tools exit more cleanly making it easier to reuse session names.
