Version 0.31.2

Bug Fixes

USB-hub nets work from lager python scripts instead of raising OSError: open failed. libusb access to a Yepkit YKUSH or Acroname hub is exclusive, and the drivers cached the open handle indefinitely — so after the first lager usb command the Lager Box server pinned the hub, every separate process (each lager python script runs in its own subprocess) failed to open it, and only a container restart recovered. Each operation is now a fresh open, operate, release cycle, serialized within and across processes by a per-hub lock; different hubs never block each other. Note: the per-operation reconnect adds roughly 2 seconds to each Acroname operation (YKUSH is unaffected at ~0.1 s).
Keithley 2281S measurement parsing. Current/voltage reads that come back as multi-field or unit-suffixed responses are now parsed robustly instead of raising or returning an incorrect value.
VISA-resource net mapping. Nets backed by a VISA resource now resolve to the correct instrument backend, fixing misrouted access to VISA-connected supplies and meters.
Windows-safe lager update. SSH-key setup and the update flow no longer crash on Windows hosts (broadened error handling around ssh-copy-id and the container update steps).
