Where can I download the older versions of the COM library?

Hi,

I was able to find the older versions of setups here https://sourceforge.net/projects/winscp/files/WinSCP/, but I need the older version of WinSCPnet.dll (specifically looking for v3.6.8). Where can I download this from?

Thanks

1. Do not use old versions of WinSCP!
2. .NET assembly was introduced in WinSCP 5.0.6
