Forge is the official HL7 FHIR Profile & Conformance editor.
Forge 23.0 for STU3 is a major update with new features and improvements and important bug fixes.
We recommend all users to update to this release.
This Forge release supports FHIR STU3.
We publish separate Forge releases for FHIR DSTU2, STU3 and R4. Subsequent FHIR releases introduce breaking changes and are not backwards compatible. Each Forge release only supports a single FHIR version and is updated separately. Different Forge releases can be installed side-by-side on the same machine.

IMPORTANT! Update to Forge End User License Agreement
Visit our company blog to read about our new licensing terms.
Forge requires the .NET Framework 4.7.2.
The .NET Framework 4.7.2 is fully .NET Standard 2.0 compliant, without any additional dependencies.
Relevant bug fixes:
Update Simplifier integration
The Import from / Publish to Simplifier commands have been updated to support the latest Simplifier API.
Serialize Logical Model to differential component
After some discussion within the community, we have changed the serialization of logical models in Forge, in order to harmonize the behavior of different kinds of
StructureDefinitions. Previous Forge releases would serialize logical model constraints to the
StructureDefinition.snapshotcomponent. As of this release, Forge will now serialize logical models to the
StructureDefinition.differentialcomponent, similar to regular resource profiles. This allows a FHIR API to generate (calculate) the snapshot component of the logical model, based on the author-specified constraints included in the differential component and by resolving any referenced external structures, again similar to regular resource profiles.
Copy global mappings
The configuration option "Copy global mappings" is now enabled by default. This option affects newly created profiles.
Enabled: initialize new profiles by copying global mappings over from selected base profile
Disabled: new profiles are initialized with empty global mappings
Improved rendering of named slices
The rendering of named slices has been updated, similar to the official FHIR website & build tool. The element tree now displays named slices as "elementName:sliceName", to clearly indicate slice groups. This also affects extension elements, which are now displayed as "extension:sliceName".
Save dialog: select output serialization format (XML or JSON)
The Save dialogs now provide distinct file type selection options (XML or JSON). Saving an existing profile to a different serialization format will automatically create a separate copy; the active document will still refer to the original file with the original format.
Note: when opening a Folder, the user can select a preferred serialization format (XML or JSON). In case a project folder contains duplicates of the same profile in different serialization formats, then Forge will only resolve and display the version with the preferred format and ignore/exclude all other versions. Generally, it is recommended to use a single serialization format per project.
Show package versions in descending order
The Package Manager shows a drop-down combobox with the available versions for each package. The package versions are now sorted in descending order, with the highest (latest) version on top.
Fix application freezes/hangs after Save
In some circumstances, the application could freeze/hang after saving a profile. This was caused by infinite recursion in broken cache invalidation logic. The relevant cache invalidation logic has been completely rewritten and optimized. Save operations more efficient, faster and no longer cause deadlocks.
Fix copy to clipboard crash
In some circumstances, when copying the message of a popup (error) dialog to the clipboard (using
Ctrl+C), the application could crash with an unhandled runtime exception. This has been fixed.
Ctrl+Con validation warning may cause freeze
Some users reported that copying a validation message to the clipboard would freeze the application, possibly because the Clipboard was unavailable. Forge now catches unexpected exceptions while copying.
FOR-316 Expand elements with complex types
In some circumstances, the previous release would not always expand children of elements with a complex type. For example, Forge would not expand children of
Extension.extension.value[x]when constrained to
CodeableConcept. This was caused by (overly) aggressive cycle detection, which is required to prevent infinite recursion. The cycle detection logic has been improved to allow child element expansion whenever applicable. Also, Forge now dynamically expands the child elements of a type choice element (
value[x]) when constrained to a single complex type - unless the type choice element is (type) sliced.
FOR-332 Show all element properties for closed slice
Forge no longer hides some element properties for a sliced element with
Slicing.Rules = closed
FOR-333 Validate slicing components during load
Forge would not validate the
ElementDefinition.slicingcomponent nor report violations during load, e.g. when the mandatory
slicing.rulesproperty is empty. This has been fixed. Forge now explicitly validates slicing components and reports validation errors during load.
FOR-335 Forge sometimes does not rename choice type elements when constrained?
This issue has been solved by #1123 (
FOR-344 sliced element can't be unsliced when cardinality is set to
Forge would prevent you from unslicing a sliced element if maximum cardinality is constrained to
0. This has been fixed.
