API · MCP
  • API: Added nights parameter to hotel stay create and update endpoints as an alternative to check_out_date — when nights is provided with check_in_date, the checkout date is derived automatically. Either check_out_date or nights must be supplied on creation.
  • API: Added custom_values response field to purchase list, detail, create, and update endpoints — returns elastic-data custom column values as a key-value dictionary. Purchase list sorting now also supports custom column keys.

API · CLI · Documentation
  • API: Added consolidated reporting endpoints — POST /v1/total-impacts/purchases/report returns product-level purchase emissions ranked by CO2e, and POST /v1/total-impacts/hotel-stays returns hotel-stay emissions (Scope 3 Category 6) with monthly buckets and weighted totals.
  • API: Added header row auto-detection for tabular imports — the header_row parameter and header_row_candidates response field let API consumers handle files with title rows above the actual column headers.
  • ⚠️ CLI: Resolved flag shorthand collisions — removed -y from --year/--registration-year (now means --yes) and -v from --verbose on vehicle diagnose/upload (now means HTTP debug). Use the long forms --year and --verbose instead.
  • CLI: Extended shell tab-completion to purchase, shipment, widget, import, and file-reading commands — widget supports two-level completion (project ID → widget ID). Also auto-registered --project-id and --file-id flag completions across all commands that accept them.
  • CLI: Routed all human-facing messages (cancellation notices, empty-result warnings, validation errors, verbose output) to stderr — --json output on stdout is now reliably parseable via pipes.
  • Documentation: Restructured CLI docs — split large pages into standalone command pages for facilities, vehicles, employees, invoices, purchases, transport, and 10+ more commands.
