This is just to announce on the news page of this mod that the new version has been released, uploaded to the site!
Most of the relevant information is in the file's description, but I might as well share a few thoughts here too.
I promised SteamPipe support, but it seems Valve didn't want to co-operate here. Even with the GNU/Linux beta of Portal 2, the VPK format remains incompatible with that used in Orange Box games. Therefore, my dream of simply mounting assets from HL2 and Portal 1 into this game has been crushed - to mitigate this, I have packed necessary assets in with the mod, which is something I never wanted to have to do. Anyway, this means that the mod, like any good mod, is now just "drop in and go" on any OS that supports Portal 2!
There are two outstanding issues, which in my opinion are quite minor. I will no longer be searching for solutions, or actively developing this mod. If solutions come my way, I will implement them and release version 2.1, otherwise, this is the final version of the mod!
