🛠️ New Forge Release – Platform Upgrades and Modeling Refinements
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. -
🌍 Explore the State of FHIR 2026 Results by Country on Simplifier.net
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. -
📌 New Simplifier.net Release 2026.3: Canonical Pinning
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.
