The update of a bqn package (e.g.,bqn-R4.0.24.bpkg) consists of two steps: first it is installed and then it is activated. The activation involves a traffic interruption of some seconds, so it is advisable to carry it out at times of low throughput.
The installation is performed in Administration->Software, clicking on the [.icon][.icon] menu icon and selecting Install… A file selector pops up to choose the package, that it is transferred to the BQN server and installed.
The activation is done in Administration->Software clicking on the [.icon][.icon] arrow icon of the package to activate (highlighted in red in the picture below).
This operation forces you to log back into the BQN after a few seconds, during which time, the traffic flow is interrupted.
