What's new in FME 2026.1

The First Drop of FME 2026.1 is Live!

Organisations are under pressure to modernise their data infrastructure while controlling costs, and FME 2026.1 directly supports this. Safe Software’s “Any Data, Any AI, Anywhere” vision is clear throughout this release. Deeper native support for existing platforms and emerging new formats means less infrastructure to manage. The sections below break down the key technical changes and the business value they give. 

Formats and Connectivity

Support for emerging new data formats and platforms continues to be an area of strong focus, with FME Form 2026.1 now supporting more than 450 formats. New and updated formats supported in this release include:

• Protomap PMTiles, a cloud optimised vector and raster format designed for scalable hosting on platforms such as Amazon S3. 
• HDF5 is an open source standard widely used for structuring large scientific and sensor datasets. 
• Microsoft Fabric Warehouse integrates directly with OneLake and leverages Microsoft Entra ID for enhanced enterprise-level governance and security. 
• Databricks Reader, native spatial types (joins, indexing, aggregations) directly in‑platform 
• Improved JSON Writer, broader support for complex JSON structures which is particularly useful for complex API payloads.

Transformers 

Transformer capabilities have also been further enhanced in this release and focus on supporting three key areas.

• The new MCPCaller transformer builds on Safe’s continuing efforts to Position FME as a no-code bridge between your enterprise and AI system. This new transformer enables users to connect to an MCP server, list and execute hosted tools, and return structured JSON results directly into FME workflows.
• Multi geometry support strengthens FME’s spatial processing capabilities, with the new GeometryCopier and updated versions of the GeometryNameSetter, GeometryRemover and GeometryExtractor providing greater flexibility when managing features containing multiple geometry fields The FeatureMerger and FeatureJoiner have seen upgrades to allow you to preserve multiple geometry columns when joining features from different streams.
• ISO-8601 DateTime fields are now easier to process, with native support being built into all workflow components with updates to the DateTime transformers, including the DateTimeCalculator and DateTimeStamper allowing you to preserve the format automatically.

Platform Enhancements 

A number of platform level new features round out the release, addressing key feedback from the FME Community. These changes have touched both Form and Flow, building upon existing functionality used every day by our clients, whilst improving on fresh features which have only recently been released. 

• FME Form Live Feature Caching: Users can now view real-time feature caches while a workspace is still executing, a substantial advantage for diagnosing issues in long running or streaming workflows.
• FME Form AI Assist: Improvements have been made to the interface to clearly highlight contextual sections of a workspace when generating or refining queries. We expect the functionality of AI assist to be expanded further in future releases, so watch this space.
• FME Flow Web Apps: Security for Flow- hosted Web Apps has been strengthened through a tokenless execution model, reducing unnecessary exposure of sensitive credentials
• FME Flow Data Virtualisation: has benefited from Callback Target support, enabling endpoints to be automatically notified when asynchronous API requests are completed without manually added polling processes.
