For the average person needing some quick answers, hopefully this thread can provide a few.
[h2]The Game you’re trying to play is using a newer / older version of the game you’re running[/h2]
If it says the server is older, it needs updating. If it says newer, you need to update.
**What is Steampipe?
Steampipe is a system that allows developers (or publishers) to push an update through Steam without having to push it through Valve first, who would then (eventually) push it out globally. This means that should any game-breaking bugs suddenly arise in the game, Garry now has the power to roll back or push out a fix near-instantly. Another upside is the way the game mounts content, it actually makes launching of the game and other things slightly faster.
**Okay, so how do I get this “Steampipe” version?
**Launch the game and it’ll ask to convert the content. Please make sure you back up any critical content as the transition may not be smooth.
Should you not be getting this question, then validate your game content instead. It should start downloading all the files.
**From a dedicated server standpoint, what does this mean?
You no longer use hldsupdatertool to grab your files, instead you use SteamCMD. Make sure you run SteamCMD at least once normally before you use it.
hldsupdater tool is now defunct and can be ignored.
What is the ID for the Garrysmod Dedicated Server files?
**I have a server and content like CSS is no longer being mounted!
Due to the way the Steampipe works, mounting now has to be explicitly stated in a file. For GSP’s this is great because you can have a basic install in one location instead of having to ship the cstrike / tf / ep2 content with every server.

I’ve updated my server, yet it still says out of date?
The base file path to the dedicated server has now changed. Previously it would be something like X:/MyServer/Path/Orangebox/Garrysmod. Instead it’s now just X:/MyServer/Path/Garrysmod. Effectively it’s climbed up a tree directory-wise.
What happens to .GCF Files?
Totally unusable. There has been mention of Garrysmod getting its own version of Hammer and so on, but whether or not these will appear, no one knows.
**Mounting content like EP1 / EP2 on dedicated servers
**My dedicated server didn’t move my files for me?
The dedicated server won’t perform any moving or transitioning of files. You must manually move them.
**How can I tell if my version is Steampipe in game?
**Look in the top right corner, if it says 165 (or above), that’s Steampipe.
X (usually CSS) content isn’t working in the game!
**Launch the game, make sure it’s running on Steampipe and also ensure it’s mounted in your Garrysmod by pressing the
button in the main menu.
