MGS v1.6.0 is our largest release since general availability. It brings your environment onto open-source Guardian 3.7, with a completely rebuilt interface including a full dark mode, a redesigned policy configurator, and a new schema editor. Schema authoring gains several capabilities that were not previously possible to express, including conditions that span schemas, geographic fields, and repeatable field groups. Dry Run is faster and easier to follow, and the API gains a general-purpose endpoint for reading policy data. Everything below is available now, with no action required on your side. One helpful thing to know before you sign in: the items previously grouped under **Hedera** now live under **Manage**. ### Built on Open-Source Guardian 3.7 This release brings in the full open-source Guardian 3.7 line, covering 295 changes merged upstream between June and August 2026, together with a substantial body of Climission work to bring those capabilities into a multi-tenant environment. The interface has been rebuilt on the current generation of its component framework, and the API reference at `/api-docs` is now a faster, Climission-branded reference. ### New Features & Enhancements #### A Rebuilt Interface The entire component layer of the application has been rebuilt. Several changes are immediately visible. * **Dark mode.** A full dark theme is now available, built on shared theme variables so every page, dialog and form follows it consistently. * **Redesigned navigation.** The menu and page layouts have been reworked, with grouped sections, tooltips when the menu is collapsed, and profile and sign-out controls in the sidebar. Items previously under Hedera are now grouped under Manage. * **A modernized login page** and a refreshed Profile General tab. * **Rebuilt notifications**, drawn from the same component library as the rest of the interface for a consistent appearance throughout. * **New Contracts and Comparison pages**, both rebuilt rather than restyled. #### Policy Configurator Redesign The policy configurator has been substantially reworked. The block tree, the properties panel and the event editor stay in step with each other, validation reports on demand so problems surface while you work rather than at publish time, and errors clear as you fix them. Save, Dry Run and publish are all reachable directly from the configurator. #### A New Schema Editor Schema authoring has been rebuilt around a new editor. Fields of every type can be added, reordered and previewed as the form your users will actually see. Sub-schemas can be nested and previewed in place, and a saved schema produces a draft version that becomes read-only once published. #### Richer Schema Authoring Three capabilities that previously required workarounds can now be expressed directly. * **Conditions across schemas.** A field's visibility or requirement can depend on a value held in a different schema, not only on a field in the same one. * **Geographic fields.** Schemas can define geographic data with cascading dependencies, so selecting a region narrows the options at the next level. * **Repeatable field links.** Groups of fields can be defined once and repeated dynamically, so a structure that appears several times only needs to be built once. #### Schema Templates Schemas can now be created from reusable templates, so a common structure can be defined once and applied across policies rather than rebuilt each time. Templates carry their own lifecycle, including apply, update and clone. #### Validating Documents Against Existing Records The document validator block can now validate an incoming document against records already held in the system, rather than only against its own contents. A validation can target a collection of verifiable credentials or presentations, narrow it by schema, ownership or assignment, filter it by comparing against fields on the incoming document, and evaluate conditions using a full set of comparison operators. This makes it possible to enforce rules such as requiring that a submission matches a previously approved record. #### A Faster, Clearer Dry Run * **Progress is visible** as a policy enters Dry Run. * **Mock data is opt-in**, so a dry run reflects exactly what you submitted. * **A simpler layout**, with the tab set collapsed into a single dropdown. * **Noticeably faster.** Mock file uploads and mock messages are handled in-process with schema records written in batches, which removes the round trips a real publish would need. Large methodologies enter Dry Run in seconds. #### API Additions * **A general read API for policy data.** A new endpoint at `GET /policy-data/query` allows policy data to be read directly, with pagination, rather than through block-specific calls. This is aimed at customers building their own front ends and integrations. * **Filtering on the policy list.** The v2 policy endpoint supports name, version and status filters. * **A policy filter for external integrations**, so connected systems can scope what they retrieve. * **Organization-level permissions**, expressed at the organization level rather than only per user. * **BbsBlsSignature2020 credential signing** is available. * **Tenant-scoped logs.** Tenant Admins can now see logs for their own tenant. #### Excel Schema Import The Excel schema flow has been improved, and the generated workbook now includes a README tab documenting the validation rules that apply, so the expected format travels with the file. ### Performance Large methodologies are noticeably more responsive in this release. * **Policy schemas load on demand**, so a large policy opens as soon as the schemas the current step needs are ready. * **Lighter block responses**, which reference schemas rather than embedding them in full. * **Faster credential processing** for documents containing geographic data. * **Faster policy loading** after a deployment, with policies loaded in parallel across available capacity. * **Reliable delivery of new versions.** Your browser picks up a newly deployed version immediately. ### Contributed Back to Open-Source Guardian Twenty-six of the improvements in this release were written by Climission and contributed upstream to the open-source Guardian project rather than kept in MGS. Every Guardian deployment benefits from them, not only ours. They include resilience improvements for Hedera mirror node traffic, more efficient handling of large task payloads, stronger file storage guarantees, safer database upgrades, clearer reporting from custom logic blocks, and more efficient document sourcing. Climission is a co-maintainer of open-source Guardian, and this is the practical form that takes. ### Documentation Documentation has been updated for the new and changed capabilities in this release, covering the new Schema Editor, geographic fields, conditions across schemas, repeatable field links, Schema Templates, and document validator source validations. Pages are written against MGS, so the labels and steps match what you see.
