Version 0.56.0

Upgrade Notes

Update your boxes. Run records, the run output folder and the nRF5340 erase fix run on the box. Run lager update --box <box-name> after you upgrade the CLI.
lager python --download no longer takes a path. Before, --download BOX_PATH copied one named file from the box. Now --download is a flag. It copies every file that the script wrote to lager.output_dir(). Change each script to write its files to lager.output_dir(), and remove the path after --download. A command line that still gives a path stops with --download no longer takes a path.
Downloads go into a new folder for each run. The CLI makes a folder in the current directory, named after the run. It no longer writes files directly into the current directory. --allow-overwrite is no longer necessary, because the CLI never overwrites a file.

Every lager python run has a run record. The box writes one JSON record for each run. The record tells what code ran, on which box and instruments, and how the run ended. It also holds the hash of the output and of each file that the run wrote. The box keeps the records of its most recent 500 runs. See the Run Record section of the lager python reference.
Each run has its own output folder. The box makes a folder for each run and gives the script its path with lager.output_dir(). The run record lists every file in that folder, with its hash. lager python --download copies all of the files and the run record to your computer, and the CLI checks each file against the record.
A script can put facts into its run record. Call lager.record_value(key, value), for example with the firmware version of the device under test. Tag a run with --label KEY=VALUE to find it later.

lager python exited 0 when the output stream ended without an exit code. A dropped connection or a box restart during a run looked like a success. The CLI now exits 255 and prints Failed to retrieve script exit code.
lager python --passenv NAME printed a traceback when NAME was not set. It is now a usage error.
lager debug <net> erase on an nRF5340 application core did not erase the flash. With J-Link V9.50, a full chip erase printed Erasing done. and erased nothing. The erase before lager debug <net> flash had the same problem. J-Link now erases the 1 MiB of internal flash from 0x0 as a range. The box then checks that the flash reads back as 0xFF, and the erase fails if it does not. The UICR is not erased.
