FME 2026.2: The Three Updates That Matter Most, Including One You Need to Fix Before Upgrading

 FME 2026.2 launched this week and, while there are tonnes of enhancements, these are the three most important with one being CRITICAL to address before you update.

A new security update affects authenticated workspaces, so if you use OAuth in systems like Azure, Dropbox, or ESRI, you need to act BEFORE you upgrade. We’ve put together comprehensive training to help you through the process – check out our online training modules at misoportal.com/online-training-modules/auth/.

1. Security Updates – ACTION REQUIRED

FME 2026.2 removes embedded browser authentication. If you created OAuth connections using the embedded browser before 2025.2, they’ll break when access tokens refresh. This impacts any authenticated workspaces connecting to Azure, Dropbox, ESRI, and similar systems, so update all affected connections before upgrading. Head to misoportal.com/fix-auth/ for detailed steps on how to fix your authentication.

Administrators also get powerful new security controls. You can select a security tier from FME Options (in FME Form) or System Configuration (in FME Flow). The selected configuration automatically distributes across all your engines while maintaining backward compatibility.

2. FME Flow as an MCP Server

FME Flow is now a Model Context Protocol (MCP) Server. This means FME workspaces become discoverable tools that any system can find and use. While AI agents like Claude, Copilot, and ChatGPT are a common use case, MCP is actually a general-purpose protocol.

So FME now connects with far more applications and tools that are in the MCP ecosystem.

3. Native Looping in Workspaces

Native looping transforms how you build iterative workflows. If you wanted to repeat a section of a workspace, you would either need to build a custom transformer or put those loops in manually creating a massive workspace. 

Now you can draw a loop box on your workspace, put your instructions inside, and FME repeats the steps automatically until the identified criteria is met. This especially good to automatically iterate through API pagination.  

Of course, there are lots of other updates. Check out the full list at community.safe.com/product-updates/fme-2026-2-feature-highlights-40528 and, once you’ve sorted your authentications, you can download FME 2026.2 at fme.safe.com/downloads/.
