Spread 3.16.1 released

It can be downloaded here.

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. This release should be significantly more stable and has fixed memory leaks, crash bugs, connection problems, and the authentication framework.

With the Spread Open Source License, the toolkit may be freely used under some conditions. For example, the license includes the requirement that all advertising materials (including web pages) mentioning software that uses Spread display a specific acknowledgement. Please review the license agreement for more details. http://www.spread.org/license/

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

For more information look at the Spread website or the changelog.

Spread 3.16.0 released -- New Open Source License

It can be downloaded here.

This is a major release of the Spread toolkit. It is now licensed under an open-source license similar to the BSD license.

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.

With the new open source license, the Apache Spread logging license and the Apache-SSL license do not seem necessary, as commercial use under the main open source license is now allowed. If you have any questions, or for more details please see http://www.spread.org/license/

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

The other major new features include support for configuring multiple interfaces on machines, a new authentication and access control framework, support for the Flush and Secure Spread projects, performance improvements to joins and leaves, the ability to have Spread generate a user name for you, and several bugfixes.

Spread 3.15.2 released

It can be downloaded here.

The new version of the Spread system released today is a minor release to fix two important, but small bugs in the java and perl libraries and to add a #define constant to the sp.h header so C programs can be conditionally compiled against multiple versions of the API.

Spread 3.15.1 released

It can be downloaded here.

A new version of the Spread Wide-Area Group Communication toolkit was released today.

Two major changes are involved in this release. First we have moved to a three numeral version number system with Major, Minor, and Patch.

The second major change is that the copyright of the Spread code developed by the original developers has officially been changed from the individual authors to Spread Concepts LLC. Spread Concepts is a company formed by the principle authors of Spread to promote the development and use of technologies for reliabile distributed systems. The company provides commercial licensing and support for Spread as well as working with other organizations to help them solve problems by using distributed systems.

The change in copyright ownership does not change any of the licenses available for Spread which are still the same. This change mainly provides increased legal protection to the developers and gives us more tools with which to promote Spread and related systems to a wider audience.

Also, a number of bugs and issues were resolved. A full list can be found in the changelog.

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.
