OpenSF v4.7.0 has been released and can be downloaded here.
User registration is required. Please find detailed instructions here.
Notice: upgrading from version 4.6 is recommended due to a serious bug that invalidates the DB connection when a simulation is aborted, requiring a restart of openSF. The bug is fixed in this release (ANR-463).
Deprecation notice: MacOS 26 is the last version of MacOS to support Intel Macs. OpenSF will be built for Intel Macs as long as reasonably possible, but users are advised that version 4.9 (expected December 2026) is likely the last version with official support for Intel Macs.

Known bugs and issues
In macOS, table columns stop auto-resizing when their size is manually changed. This is due to a bug in the underlying Eclipse RCP, with an open report.

New functionalities
ANR-418: Redesign of the openSF executions UI with a new side table
ANR-424: Post-processing tools can now run at the end of a full multi-execution
ANR-425: Switching a module in a simulation for a different version will now prompt if the files do not match exactly
ANR-427: Improvements in performance and find functionality for the openSF filesystem view
Corrections
ANR-419: Results could not be opened in a full tab until closed in the Executions view
ANR-428: ParameterEditor documentation menu was empty under macOS
ANR-440: Aborting a simulation left the “Executions” UI in an inconsistent state
ANR-444A: Modified settings from “File→Switch workspace” were ignored if the WS did not actually change
ANR-444B: When deleting a simulation, associated results folder were not always being deleted
ANR-444C: Resuming a simulation with breakpoints was broken
ANR-444D: When creating a database with a custom XML import file, if the file was invalid, the DB was created empty anyway
ANR-444E: Creating a new file in PE with certain characters in the name made the file impossible to save
Known bugs and issues
In macOS, table columns stop auto-resizing when their size is manually changed. This is due to a bug in the underlying Eclipse RCP, with Eclipse bug id #564840.
ANR-339: in Linux, the simulation editor GUI can be unstable, especially while using Wayland-based graphics. A workaround is to launch openSF with the environment variable “GDK_BACKEND” set to the value “x11”.
