Which version ?

Hello.  I am very sorry I am having a problem with which version to use.  Going through the Open Source Beehives site directly I ended up with the "AKER - Colorado Top Bar Beehive - v2.0 - Prototype - 12mm 10mm.DXF" version. However, I see here on GitHub we have the 1.0 version.  Any advice as to which version to use. 

2.0 ?

Thanks
