v1.484: fixes: ALE_2G extension, forced software build
v1.484 January 7, 2022
display:N URL parameter works again.
Admin page, extensions tab: added example of how to set USB mode.
Fixed bug where starting a forced software build ("build now" button on update tab) would
hang all connections, including admin connections, if user connections were present.
User connections are now correctly kicked prior to the build (original behavior).
