Git Question

Hello,

I am currently running git version 2.10.1 (Apple Git-78).  When I run git config —list:   it returns
credential.helper-osxkeychain
filter.lfs.clean=git=lfs clean — %f
filter.lfs.smudge=git-lfs smudge — %f
filter.lfs.process=git-lfs filter-process
filter.lfs.required=true
user.name=markwartman1
user.email=markwartman@d2l.lonestar.edu

I am following this tutorial and I expected to only see user.name & user.email, so what are the filters.lfs’s and the credential.helper?  Should I ignore them, or try to get rid of them?  Please advise.  

What is the best way to upgrade to a newer stable version of git?

Thanks,

Mark
