h1. Version 5.6 beta 1 (build 7368)

Ontotext redesigned its cluster architecture to support the case of two or more separate data centres (each with its own Master and Worker nodes), and to provide asynchronous transactions and Master fail-over. OWLIM Enterprise already supported Master-Worker clusters with Automatic Replication, Load Balancing Load-balancing and Transaction Logs, but in this release these components are improved. OWLIM 5.6 is based on 5.5 and inherits its write performance improvements.
* [OWLIM56:Client Fail-over Utility], which can be configured to fallback to the next master, if the first master becomes unavailable;
* Better TransactionLog support (see: [OWLIM56:Transaction Log Improvements]) - the updates are synchronised between all masters in all data centers;
* All Masters are now Read/Write;
