CogStat 2.4 preview release

[Krajcsi Attila]

Dear All,

The preview version of our latest 2.4 release is available! Note that this is a preview release, and it is mainly for testing purposes.

We have a tremendous amount of new features - see the release notes below.

You can download the installer from the bottom of this page: https://github.com/cogstat/cogstat/releases/tag/2.4beta . Currently, only the Windows installer and the source distribution are available. Let us know if you miss the Mac version a lot so that we'll build it faster. :) Find help on installation here: https://github.com/cogstat/cogstat/wiki/Installation .

Feel free to download and test it. Give us any feedback about the new features, and let us know if you find any bugs.

Best,

Attila Krajcsi
