Introducing PsychoPy Studio

PsychoPy Studio is a full rebuild of the PsychoPy desktop app using web-based libraries (Svelte and Electron). The underlying experiment engine (the PsychoPy library) is still Python, but Studio provides a smoother, more user-friendly interface (think drag and drop routines…) and better version independence with useVersion.

As always, the code is fully open source, you can view and contribute here. Eventually, PsychoPy Studio will replace the standalone PsychoPy app, but we plan to maintain both for a few major releases while the dust settles.

GitLab compatibility

Pavlovia will soon be upgrading to a newer version of GitLab in which authentication tokens have a maximum shelf life of 2 hours. This release of PsychoPy is the first to include automatic token renewal, allowing you to be seamlessly re-authenticated without having to manually log back in. In prior versions, once Pavlovia has updated, you will have to manually log back in every 2 hours. We apologise for the inconvenience, unfortunately this is essential for your data security.
