Fixes

• Serious snippet-related bug that appeared in the Feb 2021 update. The bug caused “Cannot use …, because it is not a variable” errors on snippet compilation. In some cases, the bug could lead to skipping of the first line of the snippet code in execution.
• Occasional blocking on ribbon buttons after losing focus in the main window.
• Bug that prevents exporting data files from Runs history, if none of the rows in the Runs panel is selected.
• Various fixes in GUI.

---

Changes

• Added ability to use external debugger (e.g. Visual Studio) for runtime snippet debugging, when an experiment is run in the Debug mode. This enables all advanced debugging features (such as breakpoints, variables watches) for the code snippets.
• New signal acquisition element, Nonin Signal, is added to the Signal processing AddIn. The new element allows online reading the pulse and oximeters XPod sensors by Nonin.
• New video recording engine replaces the old one on the elements from Usability Research AddIn. The new engine does not require installing additional video encoders allows adding sycn markers into recorded video files.
• LSL Signal element now recognize the original channels names and has a command property that allows re-request the source channel configuration, if it’s changed.

Fixes

• Incidental hangs when an experiment is run in the debug mode.
• Various fixes in GUI.
