New in InterSystems IRIS 2026.2

Using the Architect user interface, Business Intelligence users can define an analytical model that includes measures and dimensions directly based on the operational data structures. Previously, the interface leveraged relationship properties as captured in the class definition (an object-oriented development paradigm). Starting with the 2026.2 release, the interface now also allows you to leverage foreign keys, which are the recommended way to express such relationships when working in a relational paradigm, such as SQL. Since foreign key relationships may be based on more than one property, they are represented as a separate entry in the source data model tree with an “(FK)” suffix.

The integration between InterSystems IRIS and the Apache UIMA framework was deprecated in 2023.1 because the open source project has been largely dormant, with no planned maintenance to address bugs or security vulnerabilities. For these reasons, InterSystems stopped including open source libraries that had been used as part of the integration in kits. After consultation with known users, the remaining entry points to use this integration in InterSystems IRIS have now been removed from the platform entirely.

Table partitioning was introduced as an experimental feature in the 2026.1 release. The 2026.2 release improves some of its capabilities. The command for moving a partition to a target database, ALTER TABLE ... MOVE PARTITION, now supports non-default collation; it also correctly prevents the use of literals for the target database, supporting only identifiers. Additionally, an issue that caused conversions to fail if the partition key was on a field that had uppercase letters has been resolved.

InterSystems SQL supports both stored procedures and Common Table Expressions (CTEs). In the 2026.2 release, you may now use them together, creating a stored procedure that contains a CTE.

The cvendian utility, used to migrate databases between big-endian and little-endian platforms, now achieves much faster conversion times (up to twice as fast) through appropriate use of large buffers to read and write database blocks. In addition, there is now enhanced error reporting when trying to mount a partially converted database (for example, if the cvendian process was interrupted and left the database in an inconsistent state).

• Improved visibility of the toggle options to switch between the Production Toolbar view and the Host Toolbar view.

• Added ability to enter multiple values in the Categories field with a comma-delimited list.

• Added ability to rename an existing category.

• When creating a new Process class, you can now configure a new Rule to automatically invoke source control actions, streamlining class export and source control integration workflows.

• The Session Start message is now highlighted in green, reflecting the old behavior.

• Added ability to copy raw message contents from the inspector panel.

• Added an autocomplete feature on Source and Target fields of Message Search.

• Visual Trace references to a rule in an activity now link to the link and open it in a new tab.

• Added a column that indicates whether a message was resent in the messages table and in the message inspector to the Message Viewer.

• Added ability to expand the message body, header, and contents sections at the same time.

• Added a configurable notification feature that provides information when a search is started, in progress, and complete.

• Added ability to edit a saved search and to save any edits as a new search.

• Executing a saved search highlights the Saved Search icon, indicating an active saved search filter is in use.

• Find your previously searched Message Search criteria SQL query in the Search History alongside the historical search’s run time and duration.

• Message searching that use an active saved search now show the name of the saved search above the messages table.

• Disabled extended search criteria during an active search to prevent adjustments.

• Clicking the Extended Criteria icon in the toolbar now hides the dropdown; the Hide button is still available to hide the dropdown as well.

• Added an indication (an asterisk) that you have changed the criteria of a previously executed saved search before executing the new, edited search.

• Added ability to filter a trace by showing corresponding messages when right-clicking a message event.

• Added ability to load new Visual Traces in a new tab without the message viewer, enabling sharing of session links.

• Selecting two message activities now shows the time delta between the selected events.

• Added boundaries for independent scrolling in the top panel of the graphical editor.

• Added ability to alphabetically sort segment field path expressions.

• Read-only and internal properties now appear greyed out in the DTL Editor to prevent invalid mappings.

• Made the right-side inspector panel icon consistent with the show icon.

• Added more padding on text within an activity shape and truncated characters for readability.

• Enhanced multi-selected activity shapes and components when selected and focused. See an overview in the picture below.

  

• Improved automatic rearrangement of activities by reducing the number of overlapping lines on lower level activity shapes.

• Styled the Schema Viewer consistently across data standards.

• Made HL7 schema segments expandable and collapsable.

• Enhanced the HL7 Schema Segment Structure page to show the segment path of the selected segment.

• Added type, search, and filter DocType and Source constraints in text fields.

• Enhanced general usability be improving formatting and visuals, while also implementing and addressing various user-specific requests.
