Appia v4.1.0 released [18 Jan, 2009]

Appia v4.1.0 has been released. Sources and binaries can be found in the SourceForge.Net. In this release we refactored all the code to separate the Appia core and the group communication protocols.

Finaly, we added a new failure detector protocol (PhiSuspect) based on the work of Naohiro Hayashibara. This protocol was implemented by Dan Mihai Dumitriu. Thanks for the contribution!
