Kodi "Nexus" Alpha 1

So, here we go, with no further ado, we’d like to present the first Alpha releases of Kodi 20.x “Nexus”.

This is a major release, so, as you’d expect, it comes with many new features. However, it will inevitably cause problems for some people, which is why we’ll go through a more traditional Alpha/Beta/Release Candidate model. As such, then, please be aware that installing this will inevitably break things, and we’d really like your help at that point to identify the problems and get them fixed.

If you want to take the plunge, you can get Alpha 1 from here. Select your platform of choice, and look in the “Prerelease” section. Again, though, please: expect some breakage, don’t use this as your daily installation unless you know how to get things working again, and please share your experiences back with us so we can really get going on those bugs.

As usual – well, it is open source – you can see what’s changed between v20 and v19 here. It’s a long list…
