Azureus is a powerful, full-featured, cross-platform java BitTorrent client.
This release is primarily bugfixes and performance improvements, including:
Encryption bug fix
Faster crash recovery hashing
Fixed startup when config files corrupted
Data transfer from slow peers improved
how abt it still being a memory hog.. 
i think…gradually azureus fan followers r turning their faces away from azureus due to other non-java torrent dloader…like utorrent and bit comet…mainly due to max. cpu utilisation.overall speed is same in all these s/w.
Azureus 2.4.0.2 is instable in my system when using “–closedown” switch,
so degraded back…2.4.0.0
