Simplifier.
Bug fixes
Fix "Add" extension element toolbar button for complex extensions
In the previous release, Forge would generate a runtime exception when trying
to add a new element to a complex extension using the "Add" toolbar button.
The Add command has now been fixed.
Fix incomplete element expansion
In some circumstances, Forge would not fully expand all the child elements of a profile.
Specifically, Forge would not further expand any child elements of a nested BackBoneElement
(e.g. Careplan.activity.detail). This has now been fixed.
Improvements:
Implement support for Google Analytics
Hyperlinks to external websites (such as Simplifier, Profiling Academy and Firely website)
now provide custom query string parameters that specify the application name (Forge) and
version number to Google Analytics. These metrics allow us to improve our products and service.
We collect and aggregate only application-specific metrics.
The collected metrics do not identify you personally.
Firely Terminal `4.0.0` validates and runs Quality Control the way Simplifier does, and gives your pipelines better control over when a build fails. It is a major release: it runs on .NET 10 and the Firely .NET SDK 6, and a few things you may script against have changed.
The Forge 2026.3.0 release brings the two package changes Simplifier introduced this year to Forge: canonical pinning, and more than one version of a package in your project.
Simplifier now keeps every version of a package that your dependencies bring in and resolves your references predictably across them. This release also redesigns the guides overview and starts retiring DSTU2.
Earlier this year, we asked the Simplifier community how they use Simplifier, Forge, and Firely Terminal in their day-to-day FHIR work. First of all, thank you to everyone who took the time to participate.
Simplifier now runs entirely on Firely .NET SDK 6. This release brings a list of rendering improvements for your conformance resources, and consolidates our documentation in one place.
Forge 2026.2.0 upgrades the profiling engine to .NET 10 and Firely .NET SDK 6.2.1, adds support for the suppression extension, and speeds up loading of complex profiles. Quality Control now runs solely on the current Firely validator, and the Project view's Structure Type filter has been streamlined. Note that .NET 10 may need to be installed by your IT department on managed machines.
Simplifier.net now hosts country-specific results from the 2026 State of FHIR Survey, letting you explore how HL7 FHIR is being adopted in each participating jurisdiction.
This release lets you pin canonical references when creating a package, locking each one to the exact version it resolved to so your packages stay reproducible. Simplifier honours the version in a reference when resolving, with two new quality-control rules to help you pin safely. On top of that, the platform has moved to .NET 10, alongside a set of UI improvements and bug fixes.
The 2026 Simplifier User Survey is now open, and we need your input. Tell us which tools and features drive real value in your FHIR workflow, and where the platform can do better. It only takes a few minutes, and your response shapes what we build next.
