Snowray 2.1.0 adds the initial version of the new quick access component where resources can be looked up with a few keystrokes. Use the provided keyboard shortcut (ctrl/cmd + k) to access the search bar and then start filtering the available set of resources. Features like performing lexical or semantic searches in the contents of a resource, accessing issues, profiles and more will come in later releases.
Starting from Snowray 2.1.0, issues use sequential identifiers which allow users to reference them in other issues, commits, replies, and external documentation.
Snowray 2.1.0 adds new national flags for the currently supported set of SNOMED CT extensions.

Snowray 2.0.0 release brings a redesigned terminology resource maintenance and editing experience by introducing an easy-to-use Resource Management interface with the new Resource page, generic issue management for all resource types not just Value Sets, and many more features and quality of life improvements.
Snowray 2.0.0 changes the application's overall look and feel by introducing rounded corners, a new coloring scheme, and a new manta ray logo.
The new terminology resource management interface allows users to manage their resources in a list view instead of a tree view. Quick details of a resource can be opened on the right side and navigation of bundles is easier than ever. The interface allows switching between earlier versions of any resource, not just Code Systems.

📚ResourcesThe new generic issue management interface allows users to specify issues for both resources and their content. Issues can have a longer description and a list of comments that represent the conversation between the interested parties.

🗒️Issue managementValue Set Authoring has been greatly improved with the new Content tab, which allows both browsing and editing of value set clauses/members. The new page display members in tree form and updates itself semi-automatically while authoring the clause list of a Value Set. Different coloring of tree nodes helps users pick the right concepts for inclusion/exclusion and even automated suggestions and optimizations will appear in the tree with colored nodes to aid in the authoring of the given Value Set.
See more at:
AuthoringThis release now supports the latest ECL 1.6 features from the official specification and also advanced search features from the Query Language draft (semanticTag, etc.) and many others.

Snowray Value Set definition editor now accepts simple and query type reference set files as source and constructs a set of clauses from the definition described in that file. In case of a simple type reference set file, each referencedComponentId will be converted to a single equal to clause, where when importing a query type reference with a single row, the query column will be converted to a proper set of inclusion and exclusion list in the current Value Set.
Snowray now supports exporting Value Sets into a delimiter (tab character) separated format where only the list of member codes and their terms are being exported.
Snowray introduces the ability to paste large ECL expressions into the Value Set definition editor. The pasted expression will be broken up to a set of inclusions and exclusions instead of generating a single clause from it.
Snowray now displays terminology resource metadata in a more readable table format, where property keys, icons and their values are displayed.
Additional metadata information (eg. AREA and META) will be rendered on Value Set and Concept Map resources when available.

The Snowray release v1.0.0 comes with features to help with the maintenance and release of Value Set and Concept Map resources. It also improves the general performance and user experience across all features.
The new release is accompanied by this very site, which serves the purpose of documenting all functions Snowray features. With time, the content will be further extended to cover all areas in as much detail as possible.
See the official documentation page about the new Dashboard page and all its features:
🏠DashboardThis release brings a major feature that allows users to create their own SNOMED CT reference sets (as Value Sets or Concept Maps), maintain their query definitions (or mappings), release them and download them as RF2 Snapshot releases.
See the official documentation page about the new Resources page and all its features:
📚ResourcesAdministrators (aka project managers, coordinators) from now one are able to control the access for each individual resource (Bundles, Value Sets, Concept Maps). Admin, write and read-only permissions can be configured for a single user or for an entire team of users.
See the official documentation page about the new Manage Access page and all its features:
🔑Access managementThis release now supports the latest ECL 1.5 features from the official specification and also advanced search features from the Query Language draft (module, namespace, effectiveTime, etc.) and many others.
This release brings a new SNOMED CT advanced search feature to support filtering SNOMED CT content by filters like status, module, namespace, effectiveTime and advanced ECL queries.
It is now possible to import SNOMED CT RF2 Delta releases into Snowray by using the dedicated RF2 import wizard.
This release features a new copy from clipboard (browse file) feature on the Concept Map page, where users can import their own list of codes/terms (id, term columns required in this order) to support mapping them to SNOMED CT. The page also comes with a new automapping functionality to automatically map the loaded terms to the current SNOMED CT substrate and generate mappings in the current Concept Map.
It is now possible to create a Value Set based on another's definition or merge a Value Set's definition into another Value Set's current set of clauses.
See documentation for more details:
Improved format of change notification messages and commits, highlighting important information
Grouped change notifications together to reduce the amount of displayed notification popups

Snowray now comes with an improved resource selector to support searching and selection of resources and their versions in a more accessible way. The previous Dropdown widget is now gone. The widget displays all available resources (as of alpha.10 all Code Systems) and their versions in reverse chronological order. Lexical filtering and matching text highlighting is available. Up to three most recently picked resources will be remembered for quicker access.
The previous release of Snowray has come with drag and drop support on both the Value Set and Concept Map pages. Users were able to drag and drop concepts from the Code System trees as a clause during Value Set editing and as mapping source/targets during Concept Map editing. This release brings significant visual improvements to indicate the possible drop targets when starting to drag a concept from the tree.
Visualize the different drop areas when dragging concepts on the Value Set editing page:
Visualize the different drop areas when dragging concepts on the Concept Map mapping page:
Reorganizing Value Sets and Concept Maps have got a visual improvement as well. Horizontal blue lines indicate the possible drop areas when dragging Value Set or Concept Map resources in their respective tree navigators.
To support writing more complex ECL queries, Snowray now comes with server assisted completion suggestions (keyboard shortcut: Ctrl + Space), syntax validation and highlighting.
Tracking what's changed, when and who made the change is a must when it comes to content authoring environments and user interfaces. This release brings a new notification bell widget to the top right corner of the app to access the most recent 20 commits and the most recent 20 comments since the last visit. Opening the widget display a tab structure where the first tab displays the changes, while the second displays the comments. Clicking comments navigate to the Value Set clause in question. (Navigation of commits is coming in the next 1.0.0 release)
To further improve the content publishing and export experience we have made small but noticeable improvements to the file download user flow. Clicking on an Export button will now render a loading indicator until the file you have requested is not ready and allows you to download it once it's ready.
Revert and compare action icons on the history page have been replaced with better, colorful variants to match the design of the application.
SNOMED CT hierarchies now display the number of descendants available under the currently displayed concepts.
To simplify access and copy of SNOMED CT Concept IDs, Snowray now comes with a very simple copy button to copy the ID to the clipboard with a single click.
Support Enter/Esc keyboard shortcuts during Value Set clause and Concept Map mapping editing
Optimistically update Value Set/Concept Map resources to ignore rendering of a loading indicator
Optimistically update/delete Value Set clauses to avoid resurrecting clauses after deletion
