<minor version number>-<build number> like 2.1-4398, with
the change to

<mayor version number>.<minor version number>.<revision

The MIB file is now added to the firmware and can be downloaded via the Management>Access
services>SNMP page of the unit's web interface.
After loading new firmware, it may be neccesary to reload the page

the html content that is stored in the web browser's
cache. If the unit's web interface remains in the web
browser's cache then new
menu items may not be displayed.
