Previous release: v3.4.0

Summary

Adds a new export report command for exporting comprehensive device reports
in CSV format, including inventory attributes, group membership, and deployment
history.

Highlights

Device Report Export

• mender-cli export report: Export all devices with their complete
  inventory, group assignment, and latest deployment status to CSV.
• Dynamic column discovery: Automatically includes all inventory attributes
  found across the fleet as columns. Devices missing an attribute have an empty
  cell — no schema definition required.
• Pipe-delimited CSV: Uses | as the field delimiter to avoid conflicts
  with comma-containing inventory values (e.g. update_modules).
• Fixed columns: ID, LastSeen, Group, LatestDeploymentName,
  LatestDeploymentArtifact, LatestDeploymentStatus,
  LatestDeploymentCreated, LatestDeploymentFinished.
• Inventory columns: All attributes are included, sorted alphabetically and
  prefixed with their scope (e.g. [inventory]artifact_name, [identity]mac,
  [tags]environment).
• Filtering: Supports --group to export only devices in a specific group.
• Output: Writes to stdout by default; use -o/--output to write to a file.

Example Usage

# Export all devices to stdout
mender-cli export report

# Export to a file
mender-cli export report -o devices.csv

# Export only production devices
mender-cli export report --group production -o prod-devices.csv

Notes

• Large fleets: The export fetches inventory, groups, and deployment history
  for every device. For fleets with thousands of devices, this may take several
  minutes.
• Deployment history: Only the most recent deployment per device is
  included. Devices without any deployment history have empty deployment
  columns.

Upgrading

• No breaking changes. The new export command tree is purely additive.
