The SNAPSHOT for the 5.3.0.x branch uses the 5.3.0-fuse-SNAPSHOT tag. At the moment, 5.3.0-SNAPSHOT corresponds to the unreleased 22.214.171.124-fuse version.
The next major release is tracking the Apache ActiveMQ 5.3.1 branch and the corresponding SNAPSHOT tag (which has had some name changes) is 5.3.0-fuse-01-SNAPSHOT
FUSE Message Broker v5.3.0-fuse-01-00 has just been released, so it would be your best option if you are considering an upgrade. It contains all the fixes that have been incorporated into the 5.3.0.x fuse releases and the latest fixes from the Apache 5.3.1 branch.
Both the 5.3.0-psc-01-SNAPSHOT and 5.3.1-fuse-SNAPSHOT tags have been retired.
The 5.4.0-fuse-SNAPSHOT tag represents builds using the FUSE mirror of Apache trunk that are used in integration tests. These do not represent a precursor to a future release version.
