Hi all,

I'm very happy to announce the release of the Spread 3.13. This release
has seen substantial internal testing and should be both more stable and
faster then Spread 3.12. However, our testing environment is quite limited
compared to what is out there in the wild Internet, so please email me if
you have any problems or comments.

You can download the new release from the usual place:



The official announcement follows
Spread 3.13 released.

A major new version of the Spread Wide-Area Group Communication toolkit was 
released today. The major new featurs of this release are:

* Major scalability improvements. Should now support upto 990 connections
  to each daemon, thousands of groups, upto 128 daemons per configuration,
  and double the throughput for small messages.

* A new, more flexible and readable configuration file format. The 
  configuration file is now called 'spread.conf' and has a simplified
  format that also allows runtime configuration of the log format, which 
  messages to log, and a flag to disable certain dangerous monitor commands.

All known bugs are also fixed with this version. This includes a bug with 
the new NO_DROP semantics in version 3.12 and some membership crashes that 
occur under high load. Behind the scenes, this version consolidates some 
of the research done in the Center for Networking and Distributed Systems 
lab (http://www.cnds.jhu.edu) at Johns Hopkins University over the 
last few years into the public distribution.

The Non-commercial license for Spread has been updated to version 1.2. The 
changes include a clarification about Spread versions, a small addition to 
the attribution requirement and a capitalization of the word SPREAD.

Currently two freely-available commercial use licenses are available for 
Spread. One allows the use of Spread for distributed logging of Apache web 
server logs, and the other allows the use of Spread for distributed SSL 
session caching with Apache-SSL. For more details please see 

Other commercial licenses or other licensing arrangements are available. 
Please contact yairamir at spreadconcepts.com. We are looking for partners 
interested in using group communications and/or replication to solve 
demanding, real-world problems.
