Dear Alberto,

the old releases are still available on GitHub. This includes v2.20.1, which I would recommend over 2.20.0, as it contains a fix for #1394, which could lead to wrong simulation results under certain circumstances.

Cheers,
Jochen!

Dear experts,

I'd like to install the Nest version 2.20.0 instead of the last 3.1.

Is it still available for download?

Thanks
