OpenSesame 2.9.7 "Hesitant Heisenberg" released!

edited August 2015 in OpenSesame

I'm happy to announce the release of OpenSesame 2.9.7 Hesitant Heisenberg, the 7th maintenance release in the 2.9 series. This release contains bugfixes and minor usability improvements, and should be a safe and pleasant upgrade for everyone.

As always, you can download the latest version of OpenSesame from here:

Unless we encounter significant bugs that warrant another maintenance release, 2.9.7 also marks the end of the 2.9 series. OpenSesame 3.0 has been in the works for some time now, and contains lots of major improvements that I'm very excited about. If you're interested, you can already get a prerelease build, or see a(n) (evolving) list of important changes. But be warned: 3.0 is not ready for production!

2.9.7 release notes

OpenSesame 2.9.7 is the seventh maintenance release in the 2.9 series. If you are upgrading from 2.8.3 or earlier, please also read the 2.9.0 release notes.

    Thank you so much for the excellent work!

    I am a new user of open sesame. I just wonder whether the winpython based package is also available. The link on the download page seems not working.
