What Is Eclipse 4diac™?

We are preparing an update to the IEC 61499 type hash algorithm for Eclipse 4diac 3.5. This may affect even unchanged types and will require re-exporting FB types.

Update on what development happened across the Eclipse 4diac project in the week from October 30 to November 6, 2026.

This week improves library validation, Structured Text comment preservation, and the Bulk Query Editor. 4diac FORTE introduces generic multi-channel data latches, improves runtime robustness, and removes obsolete I/O modules.

We have big news: the Sovereign Tech Fund is investing in Eclipse 4diac! From October 2026 through November 2027, we will tackle a coordinated development effort across the runtime, engineering tools, libraries, and documentation.
