# Release Notes
> Latest updates to the Dcycle Developer Platform — API, CLI, and MCP Server
## July 2026
### July 6, 2026
**API** · **MCP**
* Added **land use change** (`land_use_change`) as a new GHG emission category across API, MCP, and [historical emissions](/api-reference/historical-emissions/overview) (Scope 1 — LULUCF). The MCP `get_greenhouse_gas_emissions` tool now accepts `category='land_use_change'`.
### July 5, 2026
**CLI**
* CLI: Added **SIGTERM handling** for clean shutdown in containers — the CLI now exits gracefully with code 143 when stopped by Docker, Kubernetes, or systemd.
* Documentation: Expanded [CLI docs](/cli/overview) with exit codes reference, structured JSON error output format, `auth status --check` for credential validation, automatic retry behavior, `--json` shorthand, `dcy doctor` exit codes, and `config unset`/`set` validation.
### July 4, 2026
**MCP** · **Documentation**
* MCP: Added **client-side enum validation** to [14 tools](/mcp/overview) — catches invalid `status`, `ownership`, `situation`, `transport_type`, `category`, `framework`, `impact_category`, and other enum parameters before API calls with clear error messages instead of silent empty results.
* MCP: Enriched docstrings for 9 tools with GHG scope context and usage hints, improving LLM tool discovery for `list_vehicles`, `list_employees`, `list_transports`, `list_files`, `get_recent_activities`, `list_logistics_hubs`, `get_logistics_report`, `get_custom_kpi`, and `get_kpi_campaign_values`.
* MCP: Fixed incorrect enum values in [vehicles](/mcp/vehicles), [hotel stays](/mcp/hotel-stays), [transports](/mcp/transports), and [business travels](/mcp/business-travels) tool documentation.
* MCP: Added [Gemini CLI configuration](/mcp/quickstart) to the MCP quickstart guide.
* Documentation: API response field accuracy sweep — fixed types, nullability, and missing fields across 20+ endpoint pages. Added cross-links between API, CLI, and MCP documentation.
### July 3, 2026
**API** · **MCP** · **Documentation**
* API: Added **async logistics report export** endpoint [`GET /v1/logistics/report/export`](/api-reference/logistics/get-report-export) — queues a background job to generate a detailed row-per-leg export (CSV, Excel, or JSON with optional per-client ZIP) and emails a download link when ready.
* MCP: Added initial **client-side enum validation** and enriched tool docstrings for better LLM self-correction and tool selection.
* MCP: Expanded `_INSTRUCTIONS` with workflow guidance and best practices for multi-step analysis.
* Documentation: Removed 56 internal/UI-only endpoint pages from public API docs — the developer center now shows only endpoints useful for external API consumers.
* Documentation: Fixed API base URLs from `/api/v1/` to `/v1/` and improved the [API introduction](/api-reference/introduction) with versioning and rate limit information.
* Documentation: Enriched [CLI documentation](/cli/overview) across all command pages with output examples, flag tables, JSON examples, and missing subcommands.
* Documentation: Elevated 8+ [MCP tool pages](/mcp/overview) with response examples, parameter fixes, and scope guidance.
### July 2, 2026
**Documentation**
* Documentation: Added **Common Errors** sections to all API endpoint pages with error codes, descriptions, and resolution guidance.
* Documentation: Added [LCA endpoint pages](/api-reference/lca/overview) — `create-from-json`, `create-from-excel`, `validate`, `impacts`, `export-xlsx`, and `dashboard`.
* Documentation: Added imports endpoint pages for `column-values` and `error-groups`.
### July 1, 2026
**Documentation**
* Documentation: Added endpoint pages for [imports module](/api-reference/imports/overview) (lifecycle, mapping, validation, rows), [custom KPI](/api-reference/custom-kpi/overview) (datasets, definitions, assignments), [dashboards](/api-reference/dashboards/overview), [sold products](/api-reference/sold-products/overview), [historical emissions](/api-reference/historical-emissions/overview), and logistics navigation pages.
