I apologize to those who get this twice. We have a problem somewhere
between our list software and mailserver and the mailserver rejected almost
half the recepients of the first email. I'm think I fixed the problem, so
we'll see.

Spread is a toolkit that provides a high performance messaging service
that is resilient to faults across external or internal networks. Spread
functions as a unified message bus for distributed applications, and
provides highly tuned application-level multicast and group communication
support. Spread services range from reliable message passing to fully
ordered messages with delivery guarantees, even in case of computer
failures and network partitions.
Spread is designed to encapsulate the challenging aspects of asynchronous
networks and enable the construction of scalable distributed applications,
allowing application builders to focus on the differentiating components
of their application.
A new stable version, 3.16.1, of the Spread toolkit was released today.
The main focus of this release was bugfixes, stability, and new ports:
1) Fix various races and bugs in the new authentication and access control
code.
a) Fix session establishment races with authentication
b) Add more info for access control hooks to use (mess_type and num_groups)
c) Fix so rejected messages are not still delivered to local group members.
d) Make reject messages honor SELF_DISCARD.
e) Fix bug that always allowed NULL connections.
2) SGI now builds using signed chars and reports errors correctly.
3) MacOSX build fixed.
4) Fixed race at session establishment that caused the assertion failure
"assert( xxxxx ) false "
5) Add MAX_MESSAGE_BODY_LEN to spread_params.h (used in sp.c checks), move
MAX_PACKET_SIZE to spread_params.h from arch.h.
6) Fixed interface restrictions for daemons.
7) Fixed crashes in user and flooder programs when wrong number of command
line parameters were passed.
8) Added assertion check for Groups membership message with zero members
in a group. (Theo)
9) Java library fixes and enhancements (Thanks to Dan Rall and Leonard
Richardson )
10) Fix bug in group name validator G_private_to_names that caused crash.
11) Fix for reversed parameters to memset in groups.c (Thanks to Marc Zyngier)
12) Fix bug in session connection that confused closed, but not yet deleted
file descriptors with newly accepted connections. (Thanks to
Dave Parker for discovering bug).
13) Fix significant memory leak when connections are disconnected. This
leak has been present since at least 3.15.0. (Thanks to Dave Parker
for discovering this and providing lots of assistance debugging it.)
14) Fix the binding to specific interfaces to work with broadcast packets.
(Thanks to Marc Zyngier for reporting the problem)
15) Updated man pages and Users Guide
16) Added makefile for OpenBSD contributed by Brandon Palmer.
17) Added makefile for Solaris 8 with Solaris cc compiler 6.1 contributed
by Luc I. Suryo.
