# Version 0.50.1

> September 23, 2026

## <u>Upgrade Notes</u>

* **An `i2c` or `spi` net saved with the instrument `LabJack` now fails instead of using the
  T7.** Before this release, the Lager Box sent such a net to the LabJack T7 driver. Now
  `lager i2c`, `lager spi` and `Net.get()` stop with an error that the instrument names no
  LabJack model. No `lager nets` command changes the instrument of a saved net. Delete the net
  and add it again with the instrument `LabJack_T7` or `LabJack_U3`. A net that already names
  `LabJack_T7` or `LabJack_U3` needs no change.

## <u>Bug Fixes</u>

* **An `i2c` or `spi` net for a LabJack U3 drove the T7 instead.** This happened when the
  saved instrument was `LabJack` and the Lager Box also had a T7. The net then sent its traffic
  to the T7 and reported success, and the U3 bus stayed idle. The `i2c` and `spi` nets now
  refuse the name `LabJack`, as `gpio`, `adc` and `dac` nets already do. The error lists
  `LabJack_T7` and `LabJack_U3`. The fix is in the Lager Box code, so each box must run
  `lager update`.
