Which version of Unofficial Patch Plus?

[Martin9107A]

So i've been following the guide to the letter, and i'm at the "Unofficial Patch Plus"

 

" Unofficial Patch Plus

• Author: PushTheWinButton and others
• Version: v1.38
• Installation: Install both the main file and the optional file. When installing the optional file, select [Merge], not [Replace]. "

What is the "Optional" file mentioned? i don't get an option to to [Merge] or [Replace]

 

I noticed the version numbers don't match up. 1.38 is not available on the nexus.

Current version is 1.50 with 3 additional compability patches marked 1.46

 

So should i go ahead with the Unofficial Patch Plus 1.50, and perhaps Unofficial Patch Plus - Project Nevada Patch?

 

Thanks

Just use the current version on Nexus.

 

Sadly the F&L guide is not up-to-date at this state.
