New functionalities
- ANR-056: Redesign of the openSF editors UI
- ANR-408-A: Build Mac/ARM64-native version of the openSF/PE packages and installer
- ANR-410: Combo boxes’ lists are refreshed when they are opened
- ANR-412: Notarize macOS installers
- ANR-420: Allow dialogs with tables/trees to be resized below their initial size
Corrections
- ANR-409: Paths formats are not coherent throughout openSF
- ANR-414: openSF and PE cleanup of static analysis issues and coverage improvement
- DMS-753 (no ANR): Simulation cannot be saved after switching module versions
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”.
