# Version 0.27.0
> June 12, 2026
## Features
* **Custom LabJack pin selection for i2c/spi nets.** `lager nets add` now accepts `--sda`/`--scl` (i2c) and `--cs`/`--sck`/`--mosi`/`--miso` (spi). Any DIO pin (FIO0-FIO7, EIO0-EIO7, CIO0-CIO3, MIO0-MIO2) or raw DIO number can be assigned per signal; omit `--cs` for 3-pin SPI with manual chip select. Defaults are unchanged, and pins already used by another saved LabJack net warn without blocking.
* **Net TUI pin-picker dialog.** Adding a LabJack i2c/spi net in the TUI opens a pin dialog with the historical defaults preselected (I2C: SDA=FIO4/SCL=FIO5; SPI: CS=FIO0/SCK=FIO1/MOSI=FIO2/MISO=FIO3). Duplicate pins block the save; pins claimed by saved nets warn live.
## Bug Fixes
* **Net TUI buttons no longer need multiple clicks** (a 0.25.0 regression): box round-trips ran on the UI thread and froze the interface for seconds per call, worst right after launch and on Assign Device. All box calls — assign flows, add/save, delete, rename, delete-all, edit details — now run in the background with busy indicators and disabled controls while in flight.
* **Fixed a `signal only works in main thread` crash** when TUI actions ran Lager Box scripts from worker threads; the Ctrl+C handler is now only installed for interactive command-line runs.
## Improvements
* `lager i2c` and `lager spi` display custom LabJack pin assignments with canonical pin names (for example `EIO0` instead of a raw DIO number).
* Net TUI startup is faster: the saved-nets list is no longer fetched a second time while the first screen paints.
