FME 2025.2 continues our momentum of innovation with a release focused on performance, compatibility, and developer experience. With new Delta Lake and Microsoft Fabric readers, system browser-based authentication, an IFC writer, official OS support for macOS 26 (Tahoe), and more, FME 2025.2 brings new power and reliability to every part of the platform, enabling teams to automate, integrate, and innovate with their data with greater confidence.
Feature Highlights
Delta Lake & Microsoft Fabric (Onelake / Lakehouse) Reader: The new Delta Lake Reader connects directly to Delta Lake tables and reads and processes data from Delta Lake environments. With SQL-like querying capabilities, users can easily integrate Delta Lake data into their workflows for analysis or transformation. The reader supports Amazon S3 and Azure Data Lake, with additional platforms planned for future releases.
Using the new Delta Lake Reader, FME can now connect to Microsoft Fabric’s OneLake as well, allowing direct reading from SQL Databases and Lakehouse data, including data stored on Amazon S3 and connected to OneLake via a shortcut. With Microsoft Entra ID authentication and ADLS Gen2 DFS API compatibility, data teams can automate and integrate Fabric OneLake data within FME—no manual exports or custom code needed.
Use Your System Browsers for OAuth 2.0 and Flow SAML Connections: FME Form now uses your system’s default browser (Chrome, Edge, Safari, etc.) for authenticating and authorizing FME OAuth 2.0 Web Services, and FME Flow SAML connections. This update delivers a smoother, more secure sign-in experience that aligns with enterprise IT standards.
New IFC Writer: Now out of beta, the IFC Writer aligns FME with the latest IFC 4.3 standards and BIMFitCheck certification. The upgraded IFC Writer simplifies BIM data export and improves interoperability with ArcGIS and other GIS/CAD tools, streamlining how AEC professionals move from design to operational workflows and digital twins.
Expanded Support For macOS 26 (Tahoe): FME Form now runs seamlessly on Apple’s latest operating system with full compatibility and performance. With proactive testing ahead of macOS 26’s release, customers can confidently upgrade and stay current with Apple’s evolving platform.
Additional Enhancements
FME Platform
Expanded User Parameter Support Across Platform: User parameters are more powerful and flexible across FME Form and Flow, making it easier to customize workspaces, build dynamic transformers, and create adaptable Flow Apps. New parameter types like Attributes to Expose and Encoding, along with expanded options such as Choice summaries and an improved interface for controlling visibility and baseline configuration, lets users design cleaner, more interactive user experiences without complex workarounds.
FME Form
Better Python User Experience — External Editor User Flow: The Python scripting experience is now smoother and more modern with direct VS Code and PyCharm integration. Users can write scripts using IDE tools like auto-completion, syntax checking, and debugging while retaining access to FME Objects. This makes scripting faster, more powerful, and more intuitive.
Updated Coordinate System Parameter: The Coordinate System parameter for datasets now only appears for spatial integrations and has been moved to the Parameters dialog, reducing clutter and improving consistency across workflows.
Optional Input Ports: Transformers can now run without a connected input feature, eliminating the need for adding placeholder features from a Creator. This reduces workspace and transformer parameter clutter. Existing workspaces remain unchanged, and transformers will still process the features you connect as before.
Required and Invalid Parameter Indication: The FME Form UI now follows industry best practices by marking required parameters with a red asterisk and showing invalid fields with a red outline only after edits have been made. The former red-filled fields did not always meet accessibility standards; the new approach provides clearer, calmer guidance instead.
FME Flow
Improved Developer Experience for Data Virtualization APIs: The Data Virtualization APIs now offer a better developer experience with optional long polling for reduced request overhead, flexible content-type handling for broader compatibility, and added support for JSON array schemas and modular schema referencing to simplify complex data modeling.
Parameter Pre-Loading for Flow Apps: Flow Apps now support parameter pre-loading, allowing values to be loaded dynamically before a form is displayed. Authors can pull parameters from external URLs, FME workspaces, or JSON configurations, enabling smarter, data-aware app experiences that reduce manual input and simplify multi-step workflows. An in-product guide helps users implement this feature easily.
Refreshed Navigation in the Flow UI: The Flow UI has been refreshed with a new sidebar that delivers cleaner, more consistent navigation. Collapsible sections have been replaced with a simple, always-visible layout that aligns with FME’s updated design and improves usability.
FME Realize
Straight Line Calibration: A new compass calibration method improves directional accuracy in augmented reality experiences. Simply walk in a straight line to help the app precisely align compass and orientation data. Users can either follow the prompt to calibrate, decide to skip it, or redo calibration at any time to ensure reliable AR model placement, even in challenging environments.
Transformers
StringReplacer Now Supports Multiple Replacements: The StringReplacer transformer now allows multiple replacement types in a single transformer using a new table-based interface. This update simplifies workflows and replaces the need for StringPairReplacer, which is now deprecated.
Snapper and AnchoredSnapper — Add 3D Support: Snapper and AnchoredSnapper transformers now support 3D snapping for End Point and Vertex snapping types. A new Snapping Dimension parameter lets users include Z values in snapping calculations, improving precision in 3D workflows.
Note: Support for Segment Snapping 3D is coming soon.
New and Updated Integrations
Microsoft Fabric (MS SQL and Warehouse on Fabric) Reading / Writing: FME now connects directly to Microsoft Fabric’s SQL Databases using the Azure SQL Database (JDBC MSSQL) reader/writer with Entra ID, MFA, and Service Principal support. It also supports reading data from Warehouse on Fabric, helping IT teams integrate Fabric data securely and efficiently.
Snowflake Native OAuth Support: FME 2025.2 adds support for Snowflake’s native OAuth authentication, giving users a secure and simplified way to connect without relying on external identity providers. This update aligns with Snowflake’s shift away from single-factor password logins and ensures continued compatibility with their latest security requirements.
PostgreSQL Vector Support: Initial support for pgvector enables FME to read and write native PostgreSQL vectors, enabling similarity searches and AI-driven data processing directly within FME workflows.
DropboxConnector Now Using New SDK: The DropboxConnector has been upgraded to the latest SDK to maintain secure, reliable connectivity ahead of Dropbox’s API and certificate updates in 2026.
Excel Reader and Writer Enhancements: FME now supports true Excel tables that automatically expand to include new data, plus improved handling for hidden sheets, built-in number formats, empty cells, and merged features, ensuring smoother, more accurate Excel integration.
Native Geo Parquet Support: Native support for geometry and geography types under the Parquet Geo specification allows direct storage of CRS and geospatial metadata, improving performance and compatibility for geospatial datasets.
Database Performance Improvements with "Max Features to Read Per Feature Type" Option: Database reading is faster and more efficient with optimized handling of the “Max Features to Read per Feature Type” setting, which stops reading once limits are reached. This applies across major databases, improving performance for large datasets.
