S7 Alpha pack has been updated today with many fixes, also removing a few more mods too buggy or not PvP enough, adding new transport options... We've yet to find a decent mobs mod for our Steampunk/Medieval setup, I guess we'll go without.
You may check the change logs on the Technic page if you want to know more.
Beta server is missing a mod (SC2) due to a server side bug, we'll see when the author can fix it. It's still accessible in SSP, so go test it!
We could use a couple potatoe owners to ensure it's stable enough for them, contact staff on TS to get the link.
