Game isn't updating beyond 1.8.1

[FilmForce]

I just installed KSP again after a long break, but Steam is just downloading the 1.8.1 version. Steam is set to always keep it up to date, and for some reason (I don't know why) the game is listed as "Kerbal Space Program [ 1.8.1]" in my Steam library. Is there any way to force Steam to download the most recent version, or to force an update?

The [1.8.1] looks like you previously pinned your version to 1.8.1 via Steam's beta version option.

Right-click on KSP, go to Properties -> Betas and select "NONE" from the list.

If KSP is listed with [1.8.1] after it in your Steam library then you've set it to download 1.8.1 specifically and not update beyond it. It's probably because you have/had mods installed that wouldn't work with 1.9, but there's a way around the problem entirely:

• Copy the entire KSP directory out of Steam and put it somewhere else. Install mods on that one and Steam will never update it. You can even download multiple different versions of KSP and put different mods in each; CKAN is particularly good for doing this but you can do it by hand if you want.
• Leave the version inside the Steam folders free to update when new game versions are released. It won't affect your modded games, break saves or anything else because it's a separate copy of KSP.
