Hello All,

but especially Albert Grippo, Bill Brown, Bob Dalesio, Daniel Bogard,
Johnny Tang, Jordi Delgado, Josep A. Perlas, Masahiro Kaji, Kevin
Tsubota, Timo Korhonen, Marty Kraimer, Mauro Giacchini, Nicholas P.
DiMonte, Noboru Yamamoto, Paul Sichta, Peter Mueller, Till Straumann and
Yves Lussignol.

The latest release 2.4 of the LanGpib package is now available for
download at

	http://www-csr.bessy.de/control/SoftDist/gpib/index.html

I encourage everybody who uses LanGpib to upgrade to this version,
(especially if they use EPICS R3.13.1). It contains a number of
bug-fixes, mostly concerning SRQ-related behavior. People who still use
older versions (prior to 2.x) may need to change their setup a little,
but you'll be glad to hear that most things have become simpler since
the old days. The documentation has been completely revised to reflect
the various changes that happened over the last year(s), though it is
probably far from being complete.

I want to use the opportunity, to thank all the above listed persons - I
hope I did not forget anybody - for beta-testing all the earlier
versions. Especially Peter Mueller and Till Straumann from the PTB have
made invaluable contributions, not only by testing and bug-tracking but
also by directly hacking the code.

This will be the last major release of the LanGpib package. I will
incorporate bug fixes but won't add anymore additional features. The
reason is that I want to concentrate on a completely restuctured
unbundled version of EPICS GPIB support. This will make it possible to
use different interface hardware (such as HP E2050A, NI1014,
Bitbus-Bugs, MPF (formerly HiDEOS) driven IP-Carriers, hopefully also
ET488, and whatever new hardware appears) on the same IOC. The plan is
to achieve this by abstracting the GPIB specific semantics into a
generic driver that co-operates with down-scaled hardware specific
low-level drivers. The first steps in this direction have been done
already, but it's impossible to say when this project will reach
alpha-release status.
