MGS v1.1.1

Improvements to the Policy API surface: cleaner self-documentation, support for nested URL paths in policy aliases, and a fix to a DMRV GET route.

New Features & Enhancements

Nested URL Paths in Policy Aliases

Policy authors can now use nested, slash-separated paths when defining policy aliases (for example, dmrv/farm/measurements). Previously, aliases were restricted to a single flat segment, which made it harder to organize multiple DMRV endpoints under a clean, hierarchical URL structure.

• The alias validator and Swagger documentation now accept nested paths.

• Existing single-segment aliases continue to work exactly as before.

• The change is reflected in both the policy configuration UI and the generated API documentation.

A Cleaner Policy API Self-Documentation Response

The policy /about endpoint, which describes the public API surface of a published policy, has been tidied up so its output is easier to consume by downstream tools and integrations.

• Schema identifiers are now returned without the leading # character, matching how they are referenced everywhere else in the platform.

• Block documentation URLs are now consistently constructed with a /blocks segment, so callers no longer need to special-case different URL shapes.

Quick Feedback When Copying from the API Documentation Dialog

The API Documentation dialog, which policy authors use to inspect and share the public surface of a policy, now shows a brief confirmation toast whenever a URL or identifier is copied to the clipboard. This removes the small uncertainty about whether the copy action took effect.

Platform Stability

DMRV GET Endpoint Routing Fix

A GET request to a DMRV endpoint without query parameters now correctly matches the /tag/:tag/blocks URL advertised in the policy's own API documentation. Previously, the request would fall through to a different handler in certain cases, returning an unexpected response shape. Integrations that rely on the published DMRV URLs will now behave consistently with what the documentation describes.
