Most significant change in this release is the anonymization of probes on the client-side. Previously "private data" (like IPs, MACs, serials, hostname, username, etc.) was removed on the server-side. But now you do not have to worry how server will handle your "private data", since it's not uploaded at all. You can now upload probes from any computers and servers w/o the risk of security leak.
Summary: improved privacy, faster probing, probe USB drives, probe MegaRAID, probe via sudo, improved detection of hardware, Deb package.
