[DOC] Migration document is bit confusing regarding LevelDB support offered in 6.1

The JBoss A-MQ 6.1 migration guide Technical Preview section still lists the LevelDB persistence store. Feature is documented as follows:

Feature Previews
Technical previews of features in development
The following features are included in the JBoss Fuse 6.1 release in order to let you preview technology that is currently under development. These features are not yet supported and are not suitable for deployment in a production environment.

LevelDB store (on selected platforms)
Red Hat JBoss Fuse includes a technical preview of the new LevelDB store, which uses Google's LevelDB library to maintain the indexes in the log files. The LevelDB store supports XA transactions in ActiveMQ 5.9. The LevelDB store is available only on Windows, Linux, and Mac OS platforms.

Note
The LevelDB store is provided with native libraries on Linux only. On all of the other supported operating systems, LevelDB is provided as a Java implementation.
Important
This is a technical preview only. The LevelDB store is currently not supported and is not suitable for deployment in a production environment.

This is a bit confusing as the JBoss A-MQ 6.1 Configuring Broker Persistence Guide states the LevelDB Store is supported on Linux platforms [1].
